I use a ESP8266 module for irrigation. I read humidity setpoint from nodered dashboard and some data in return back to nodered. Humidity, ip address, rssi and temp. It worked fine. I added a function for reading consumed water. Still working fine, but after a while the debug node only logged the hum…

[image] JohanR: Any idea why the mqtt in node is reading when using W4/bev/+ but not when using for example W4/bev/flow Do you have a space at the end of the topic name?
