I got everything working properly on the 0.9beta, on a nodemcu with bme280,bh1750, and srx882/stx.
The problem is that although the “debouncing” works sometimes (i.e. the OMG will only publish an RF code once and then ignore it for a few seconds), other times it sends the same code rapidly 2-4 times in less than a second. The result is my HASS turning the light rapidly on and off since the mqtt switch toggles my light.
In this mqtt gateway client screenshot you can see the code being sent once and then the HASS sending the light ON command, and then on the next time i press the RF button, the code is sent 4 times rapidly and then the HASS sends light ON/OFF commands rapidly 4 times (the last one is another time where the receiver picked it up wrongly)
Also, i see it was mentioned here a few months back, but didnt want to bump old threads:
