Pod
The pod names itself from its MAC address at boot — it prints
device_id=… on the serial console. Give it a name you will recognise;
the ID is what the backend keys on.
Setup — which sensors and actuators are fitted
Tick what is physically wired. The dashboard then shows a fitted-but-silent channel as no signal instead of hiding it, so a failed sensor is visible rather than absent. Saved in this browser only.
One channel per probe.
Analog. Must be on GPIO 4–10 (ADC1); ADC2 pins do not read while WiFi is on.
Each sensor reports two channels, temperature and humidity.
Sensors
Nothing configured or reporting yet.
- Open Setup above and tick what you have wired.
- Check the Device ID matches what the pod prints at boot.
- A
devicesrow must exist for that ID or telemetry is dropped silently.
Channel 4 — irrigation output
The pod switches the load off by itself when the timer expires, even if it loses connectivity. It never waits for an off command.
