Flashing

These switches come preflashed with custom tasmota firmware, which leaves no space for an ESPHome binary OTA update.

If you would try to flash it with an ESPHome binary - update will fail.

This can be worked around by flashing the device with a Tasmota minimal binary first, then re-flashing with your ESPHome binary.
