Wired install

All install options. No adapter? Try the no-wire install.

This backs up your chamber, checks that the chip is safe to write, and then installs AutoMyco. Everything happens in this browser, and your backup never leaves your computer.

Before you connect

Unplug the UV-C lamp (UVC1) from the board before anything else. UV-C light damages eyes.

The UV-C lamp (UVC1) is unplugged. My adapter is set to 3.3 V, and its VCC pin is not connected. The chamber is powered from its own supply. Wires go to the 7-pin header: adapter GND to pin 6, adapter RX to pin 5 (TX0), adapter TX to pin 4 (RX0), and adapter RTS to pin 3 (EN). I understand the flasher will back up my chamber first and won't write anything until that backup is saved. I accept the terms of use and install at my own risk.

Pin 1 is the end nearest the HDC1080 and ring-light connectors, and it carries 5 V. Don't connect it. Pin 7 is the end nearest the FAN1 connector and the mounting screw.

Wiring diagram. Chamber header pin 3 (EN) to adapter RTS, pin 4 (RX0) to adapter TX, pin 5 (TX0) to adapter RX, pin 6 to adapter GND. Pin 1 is 5 volts and must not be connected; pins 2 and 7 are not used. Adapter at 3.3 volts with VCC not connected.

Connect

Hold the button on the back of the chamber, click Connect, choose your adapter, and keep holding until the status says Connected. Holding the button puts the chip into download mode.

Don't hold the button for long while the chamber is running normally. A long press on the stock firmware wipes its settings.

Stuck? See Help for wiring and download-mode tips.

Back up your chamber

Reads all 4 MB of flash twice and checks that both reads match, then saves the file. Allow about 6 minutes.

Install AutoMyco

Erases the chip, writes the firmware, then reads it back to check. This also wipes the stock settings, including your saved Wi-Fi password.

Replace the stock firmware on this chamber.

Put the chamber on your Wi-Fi

Leave the adapter connected. The flasher sends your Wi-Fi details to the chamber over the same cable. They go straight to the chamber and are never sent anywhere else. AutoMyco has no setup hotspot.

Network name Wi-Fi password

2.4 GHz networks only. Click the name box to pick from the networks the chamber can see.

Later, without a computer: the chamber also accepts Wi-Fi over Bluetooth from the Home Assistant app or improv-wifi.com (Chrome). When it asks you to authorize, press the button on the back of the chamber once, briefly (a 5-second hold starts the self-test instead). It works within 30 minutes of the chamber starting up; after that, unplug it for 10 seconds first.
