I have OMG working on a WROOM ESP32 as a Bluetooth to MQTT Gateway. It works great! Thanks! I was wondering if I could directly add an RX480e or other cheap 433Mhz receiver to the ESP32’s IO pins and have OMG receive messages from 433Mhz devices. I am currently doing that with Tasmota on another board.
I don’t have tested it, if you haven’t purchased it I would suggest the ones that we propose in the docs.
RCSwitch should work with the BT gateway as it is not very resource demanding. It would give you undecoded data. Interesting for switches but not for sensors.
RTL_433 is more interesting for sensors but requires a LoRa SX126X module and is not yet compatible with the BT gateway.
