Is it possible to integrate this or does it already exists? My intention is to use mqtt to send json commands which controls a arduino connected to OMG, using it on espurna now but want to change to minimize the amounts of esp’s.
The arduino is controlling 3 pwm fans, so maybe I’m able to control them directly from the esp32
I was thinking a component named ZgatewaySerial using the RX and TX pin
and communication with something like commands/MQTTtoSerial (no json support from OMG only passing the message to connected device) commands/MQTTtoSerial/config (for buadrate, 8N1 and tx+rx or rx or tx) SerialtoMQTT (response from connected device)
This would could possible create some problems for the Serial print from the OMG itself, so it should probably get disabled.
