Notes

Using GPIO 1,3

If your device uses the GPIO pins 1 (serial0 TX) or 3 (serial0 RX)for channels, you need to disable logging via the serial port:

mos config-set debug.stderr_uart=-1 debug.stdout_uart=-1

Using ESP8285 or 1MB ESP8266

You need to flash with the following statement in mos.yml:

build_vars:
  FLASH_SIZE: 1048576

Note: OTA will not work on these devices, for lack of flash space for the alternate boot partition.

Using Sonoff-4CH

Sonoff 4CH uses a bunch of GPIO pins for the LEDs and pushbuttons, and as such has no space for sensors.

mos config-set app.config=sonoff-4ch.json sensors.dht_gpio=""
