Hello, I observe quite strange behavior with MQTT Client. I have MQTT Hub, where all devices are published to topic homie/homey-5dd…1/# I also have other devices which publish messages like openHab/# and UPS/# I have two flows which subscribe to topic: UPS/status and openHab/Okno3/BlindsControl. …

I am seeing promising results too… will post if I find anything ‘strange’ (Ignoring some v6 beta issues)

Great work Harrie… So far so good. The disabling of flows error (flows which used MQTT client) doesn’t occur anymore. These flows use # wildcards to listen for certain text. For me the disabling flows error would previously occur when ever I tried scanning for new Tasmota devices in the Tasmota Ap…

One week past. I’m curious if anyone had any issues with the beta/test version of the MQTT Client app? @scanno did you get any reports? How many users installed the test version? And the connection dropouts between apps? Are regular app restarts still needed? And Homey responsiveness? Became wors…
