I have a RPi 2B+ running OH 2.4.X After many attempts, I finally got OH up and running. After a lot of searching, I got MQTT working and have added a relay to control a light. A major accomplishment for me. The next project I’m working on is adding the BMP280 temp, humidity & pressure sensor to OH…

Create a Number channel in your MQTT thing The state topic should be: tele/BME280-1/SENSOR Then click SHOW MORE and put this in the incoming value transformation: JSONPATH:$.BME280.Temperature You should also ensure that the JSONPATH transformation service is installed in the paperUI

Anytime I swap firmware I use esptool to do a complete erase of the chip. The command is easy > esptool.py erase_flash

Something that might help with the new mqtt binding.
