Hypha Aeris — Closed Beta Guide

    Everything you need to set up and run your closed-beta unit.

    Closed beta notice

    Aeris is pre-release hardware running pre-release firmware. Things will change, data may be reset, and some updates may require you to pair your device again.

    When the beta program ends, we will send you a return label for your unit. Nothing to arrange on your side.

    Do not rely on Aeris as your only environmental alarm. Keep whatever alarms and safeguards you use today. A missed alert costs a crop, and during beta we cannot promise Aeris will catch one.

    In the box

    • Your Aeris
    • Mounting hardware — a standoff, a plate with a hex nut embedded in it, and a bolt
    • A hex tool for the bolt
    • A 3 m USB-C cable

    You supply the USB-C power adapter. Any standard phone charger will do.

    1. Set up your Aeris

    Setup at a glance Five steps in order: plug Aeris in, wait for the light to blink blue, scan the QR code with your phone camera, follow the guided steps in the Hypha app, and wait for the success message. 1 Plug in 2 Blinks blue 10-min window 3 Scan the QR phone camera 4 Follow the app WiFi, elevation 5 Success light goes dark
    Setup, start to finish.

    Before you start

    • Install Hypha on your phone and sign in. Get it at demetermycolabs.com/download — it is on the App Store and Google Play. You need an account; setup will not run without one.
    • You need 2.4 GHz WiFi. Aeris does not join 5 GHz networks. If your router combines both under one name, setup usually still works — but if it fails, this is the first thing to check. Have your network name and password handy.
    • Turn on your phone's Bluetooth.

    Steps

    1. Plug it in. The light flashes white twice as it powers on.
    2. Wait for the light to blink blue. Blue means Aeris is ready to set up. You have 10 minutes from the moment it powers on. If the window closes, unplug it and plug it back in to start over.
    3. Scan the QR code on your device with your phone camera. Hypha opens Add Device. Tap Scan for devices — the list will show only your unit.

      No QR? Open Hypha → Add device → Scan for devices, and choose the unit whose code name matches the one printed on your device (for example, Cosmic-Enoki).

    4. Follow the steps on the Add device page. Hypha guides you from here. It asks for your WiFi network and password, then for your elevation — optional, but the CO₂ sensor reads low in thin air unless it knows how high you are.
    5. Wait for “Success! Go to device.” The light turns amber while Aeris joins your WiFi, then goes dark — blinking green for a moment every 10 seconds as it sends each reading. A dark light is what working looks like.

    2. What the light means

    Aeris has one status light, and it tells you what state the device is in.

    When Aeris is working normally, the light is off. It blinks green for a moment every 10 seconds as each reading is sent. A dark light is a healthy light — it does not mean the device is asleep or dead.

    Aeris status light patterns over four seconds Six timing strips showing how each light state blinks: white double flash on power-up, blue 400 milliseconds on and off when ready to set up, amber the same rhythm while joining WiFi, a brief green pulse every ten seconds when working, red one second on and one second off when the setup window closed, and three fast red flashes when WiFi settings are cleared. What the light is doing Each strip covers 4 seconds. Filled = lit, grey = dark. White · 2 quick flashes Powering on Blue · blinking Ready to set up Amber · blinking Joining your WiFi Off, brief green blink Working normally · every ~10 s Red · slow blink Setup window closed Red · 3 fast flashes WiFi settings cleared

    3. Where to put it

    Put Aeris in the same air as your mushrooms. A sensor sitting outside the tent, tucked into a far corner, or pressed against the ceiling is measuring a different environment than the one your blocks are fruiting in — and it will report those wrong numbers with total confidence.

    In a tent or monotub, mount it above the midpoint. High enough to stay clear of standing water, misting, and the soaked air right at the substrate surface, while still sitting in the fruiting space with your mushrooms. Concretely:

    • In a grow tent, fix it to the rack, just below the top row of blocks.
    • In a monotub, mount it on one of the air holes in the side of the tub — never resting on the substrate.
    Where to mount Aeris inside a grow tent Cross-section of a grow tent. Aeris is fixed to the rack just below the top row of blocks, above the dashed midpoint line. Three crossed-out positions are shown: outside the tent where it reads room air, directly in front of the fan, and down at floor level in the wet zone. Where to mount it — grow tent GROW TENT MOUNT HERE — on the rack, under the top row midpoint blocks NOT UP ĝ · n̂ ≥ 0 wet zone — misting, standing water fan outside the tent — reads room air not in the fan’s path not at floor level
    Fix it to the rack, just under the top row of blocks — not outside the tent, not in the fan’s path, not down in the wet zone.
    Where to mount Aeris on a monotub Cross-section of a monotub with a plain clear lid and air holes drilled through the side walls above the substrate. Aeris is mounted on one of those side holes, marked correct. A crossed-out position sits down at the substrate surface in the wet band, where mushrooms are fruiting. Where to mount it — monotub MOUNT HERE — on a side hole substrate NOT UP ĝ · n̂ ≥ 0 not on the substrate mounts on a side hole, plate on the outside air holes in the tub sides
    In a monotub, mount it on one of the air holes in the tub’s side wall. The band just above the substrate is the wettest air in the tub.

    Do

    • Mount it inside the fruiting space, close to the mushrooms.
    • Keep it above the midpoint — on the rack in a tent, on a side hole in a monotub.
    • Leave a few inches of clearance around the air intake so air can move freely across it.
    • Keep the intake unobstructed and clear of dust.

    Don’t

    • Don’t mount it outside the tent or tub, where it measures room air instead of the air your mushrooms are in.
    • Don’t put it directly in the output path of a mister, fogger, or humidifier.
    • Don’t put it directly in front of a fan. Moving air skews temperature and humidity, and biases the particulate readings.
    • Don’t put it anywhere it can be dripped on or sprayed directly.

    Never let it get wet

    Aeris is not sealed. The openings in the case are open — water that reaches them lands directly on the sensor and the electronics, and that damage is permanent.

    An Aeris sitting half-submerged in water, its vent openings at and below the waterline, marked as something never to do.
    Never — water will destroy it
    • Never submerge it, even for a second.
    • Never rinse it under a tap, and never wash it — including when you are clearing a blocked intake.
    • Keep it clear of direct mist and spray, and out from under anything that drips.

    4. Mounting it

    The mount kit is a bolt, a plate with a hex nut embedded in it, a standoff, and the hex tool that tightens the bolt. Which parts you use depends on where it is going.

    Which way to mount it

    Some faces of the case are stamped NOT UP. Those faces must never point toward the ceiling. Any orientation that keeps all three of them pointing sideways or downward is fine.

    Two things go wrong when one points up. The air sensor is compensated for a particular mounting orientation, and turned the wrong way it reads its own heat instead of your tent — temperature and humidity drift off. And the USB-C port ends up facing the sky, where condensation and stray drips run straight into it.

    The marking is on the case itself, so any mounting position can be checked without this page — find the three NOT UP stamps and confirm none of them face upward.

    These are fine

    Aeris mounted correctly — no NOT UP face is pointing upward.

    On a grow tent rack

    The simple case: you do not use the standoff. The bolt passes through the hole in the Aeris case, up between two wires of the shelf, and threads into the plate — clamping the wires between the case and the plate.

    How the rack mount goes together Exploded view down the bolt axis. Aeris hangs beneath the wire shelf. No standoff is used: the bolt passes up through the Aeris case, between two shelf wires, and threads into the nut embedded in the plate resting on top, clamping the wires between the case and the plate. Grow tent rack mount — order of parts No standoff on a rack. Aeris hangs underneath, and the shelf wires are clamped between the plate and the case. plate sits on top, nut embedded inside wire shelf wires seen end-on; the bolt passes between two of them Aeris hangs under the shelf bolt goes in from underneath bolt threads up into the plate
    On a rack it hangs: plate across the wires on top, Aeris underneath, bolt up between two wires.

    Give the cable a drip loop. Hanging under a shelf, the USB-C plug points out to the side, so water running along the cable would head straight for it. Let the cable hang below the plug before it goes anywhere else — the lowest point should be the loop, not the connector.

    How to give the USB-C cable a drip loop Two examples of an Aeris hanging under a shelf with the USB-C plug out to the side. On the left the cable dips below the plug before running on, so water travelling along it collects at the bottom of the loop and drips off. On the right the cable rises away from the plug, so water runs back down the cable and into the connector. Give the cable a drip loop DO NOT UP ĝ · n̂ ≥ 0 drips off here NOT THIS NOT UP ĝ · n̂ ≥ 0 runs into the plug Cable dips below the plug — water collects at the bottom of the loop and falls away. Cable rises away from the plug — water runs back down it and into the connector.
    The lowest point of the cable should be the loop, never the plug.

    In a monotub

    Here the mount passes through the wall of the tub, so Aeris sits inside breathing tub air while the plate holds it from the outside.

    1. Mount to an existing hole in the side of the tub, above the substrate line. The plate has to seat flat on the wall around the hole, so the hole must be smaller than the plate.
    2. Turn Aeris on its side — see Which way to mount it above and check no NOT UP face ends up pointing at the ceiling.
    3. Pass the bolt through the case and thread it into the plate held flat against the outside of the tub wall.
    4. Tighten with the hex tool until it sits firm.
    How the monotub mount goes together Exploded view along the bolt axis. From inside the tub outward: the bolt passes through the Aeris enclosure, then an existing hole in the monotub wall, and threads into the nut embedded in the plate on the outside. No standoff is used. Monotub mount — order of parts INSIDE THE TUB OUTSIDE bolt NOT UP ĝ · n̂ ≥ 0 Aeris bolt hole in the case monotub wall existing hole plate nut embedded inside bolt threads in from the inside
    The tub wall ends up sandwiched between the case inside and the plate outside.

    Known issue — do not use the standoff

    Your kit includes a standoff. Leave it out for now. We have found it does not fit most monotubs, and we are working on a fix. The steps above are the method to use in the meantime.

    Getting power in

    The USB-C cable needs its own way out of the tub. Run it out through a second hole, cover that hole with micropore tape, and cut a slit in the tape just big enough for the plug to pass through. The hole keeps breathing, and the cable runs out to power.

    In a tent, just use the cord port your tent already has.

    Running the USB-C cable out of a monotub Cross-section of a monotub with mushrooms fruiting from the substrate. Aeris is mounted on a side hole, and its USB-C cable runs down and out through a second, lower hole. That hole is covered with micropore tape with a small slit cut in it, so the hole stays filtered while the cable passes through to a power supply outside. Getting power in — run the cable out a second hole substrate NOT UP ĝ · n̂ ≥ 0 Aeris on the mount hole to power second hole, covered with micropore tape and a small slit
    One hole carries the mount, a second filtered one carries the cable.

    5. Your readings

    Aeris measures:

    ReadingWhat it is
    CO₂Carbon dioxide concentration, in ppm
    TemperatureAir temperature at the device
    HumidityRelative humidity at the device
    PM1.0 / PM2.5 / PM4 / PM10Airborne particulate at four sizes, including spores and dust

    Good numbers depend on what you are growing, so Aeris does not ship fixed thresholds. Set your own target ranges to suit the species in front of you. Recommended grow profiles are coming in a later release.

    Once a month, give it fresh air

    Aeris uses fresh air as its reference point for CO₂. Shut inside a tent it never sees that reference, and its CO₂ readings drift out of true — slowly and quietly, so nothing looks wrong.

    Once a month:

    1. Unplug Aeris and take it out of the tent.
    2. Somewhere with fresh outdoor air, plug it back in.
    3. Leave it running for 5–10 minutes.
    4. Put it back.

    6. Firmware updates

    Aeris installs firmware updates when it restarts, in the first 90 seconds after it powers on. There is no “check for updates” button and nothing to download.

    During beta we will send you a notice when an important update is ready. Unplug Aeris and plug it back in, and it will pick the update up as it boots.

    An update takes about 1–2 minutes. Hypha shows an Updating firmware indicator on the device page while it runs.

    Let the update finish. Wait for the Updating firmware indicator to clear — the device itself gives no sign that an update is running. If it does lose power partway, nothing is damaged: Aeris keeps the firmware it already had and picks the update up on the next restart.

    7. Change your WiFi, or start setup over

    Aeris has one button. Holding it clears the saved WiFi network and returns the device to setup mode.

    Your device stays on your account. This clears the WiFi settings only — it does not unregister the device or delete your readings.

    Timing for clearing WiFi with the button A timeline from zero to eighteen seconds. The window opens once the two white power-on flashes have finished. Start holding the button within the first ten seconds, hold for five seconds, then release. Both the press and the release must happen inside the eighteen second window. On release the light flashes red three times and Aeris restarts into setup mode. Clearing WiFi — the timing is the hard part 18-second window — opens after the two white flashes start your hold in here hold — count to 5 light stays off while you hold let go here 3 red flashes, then it restarts into setup plug inwhite ×25 s 10 s15 s18 s
    Start the hold early. Both the press and the release have to land inside the 18-second window.
    1. Unplug Aeris, then plug it back in without touching the button.
    2. Wait for the two white flashes. The button does nothing until they have finished.
    3. Press and hold the button for 5 seconds, then let go. Start within about 10 seconds of the flashes.
    4. The light stays off the whole time you are holding. That is normal. Don’t let go early because nothing seems to be happening.
    5. On release, the light flashes red three times and Aeris restarts into setup mode.
    6. In Hypha, open Add device → Scan for devices, and set it up again with your new network.

    If nothing happens, unplug it and try again. Both the press and the release have to land inside the window, which is why it pays to start as soon as the flashes finish.

    Use Add device, not the QR code. Aeris is still on your account, so scanning its QR opens the device page rather than setup. There is no need to unregister it first — pairing a device you already own is expected and works normally.

    8. Troubleshooting

    The app can’t find my device

    1. Check the light is blinking blue. If it isn’t, unplug Aeris and plug it back in, then try again within 10 minutes.
    2. Make sure Bluetooth is on.
    3. On Android, confirm you granted location permission when Hypha asked.
    4. Move your phone closer to the device.

    “Wrong password”

    Check your WiFi password and try again. Passwords are case-sensitive.

    “Network not found”

    Check the network name (SSID), or move Aeris closer to the router. Remember that Aeris only joins 2.4 GHz networks — if you only see 5 GHz networks listed, that’s the problem.

    “Connection timed out”

    Try again, or check your router. If it keeps happening, move Aeris closer to the router for setup — you can move it back afterwards.

    “Could not get an IP address”

    Your router didn’t assign Aeris an address. Try again, or restart your router.

    “Bluetooth connection to the device was lost”

    Stay near the device with the app open, and try again.

    “Your device joined WiFi but has not checked in yet”

    Aeris is on your network but hasn’t reached us. Stay nearby with the app open and try again. If it keeps happening, report it — this one is worth telling us about.

    My device stopped sending readings

    Start with the light:

    • Amber, blinking — Aeris lost your WiFi and is trying to rejoin. It keeps retrying on its own, so if your router was off or restarting, give it a minute once the network is back.
    • Off, with a green blink every 10 seconds — it is still sending. Check the device page in Hypha, and if the readings there are stale, tell us.
    • Nothing at all — check the cable, the adapter, and the socket.

    If it stays amber, unplug it and plug it back in. That clears most cases, and it picks up any pending firmware update at the same time.

    If it returns straight to amber and stays there, your WiFi has probably changed — a new router, a new password, or a renamed network. Clear the WiFi and set it up again, as in Change your WiFi, or start setup over.

    The light is off and I don’t know if it’s working

    That’s normal. Aeris keeps its light off while running, with a brief green blink every 10 seconds as it sends a reading. Check the device page in Hypha for a recent reading — that’s the reliable answer.

    Hypha says the fan is blocked

    Check the air intake for dust or obstruction and clear it. Keep it dry while you do — never rinse Aeris or hold it under a tap. See Never let it get wet.

    9. Safety and legal

    Aeris is not a safety device. It is not certified or intended as sole or primary control for life safety, fire suppression, emergency ventilation, CO₂ or oxygen hazard mitigation, or any system where failure could cause death, serious injury, or major property damage. Maintain independent alarms, ventilation, and safeguards as required by law.

    FCC

    This device has not been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased, until authorization is obtained.

    Warranty

    Beta units are provided for evaluation. They remain the property of Demeter Mycolabs and carry no warranty. We will send a return label when the program ends.

    Your data

    Aeris sends two things to your Hypha account:

    • Readings — CO₂, temperature, humidity and particulate, with timestamps.
    • Device diagnostics — firmware version, uptime, sensor health, and update status.

    Your WiFi name and password never leave the device. They are stored on Aeris itself and are never sent to us. We do not collect your network name, your password, or anything else about your network.

    In the app we hold your account email and whatever you create — notes, labels, strains, grow records, and photos you upload. Feedback you send includes the screen you were on, plus a screenshot only if you choose to attach one.

    You can delete your account and its data from Hypha’s settings. The privacy policy covers retention, sharing, and your rights in full.

    Telling us about problems

    Tap the message icon in the top-left corner of any screen in Hypha. It opens a short feedback form and lets you attach a screenshot. You can also email support@demetermycolabs.com.

    Either way, tell us:

    • What you expected, and what happened instead
    • Roughly when it happened
    • A screenshot, if there’s something to see
