MQTT Publish working but subscribe hangs device

[tobievii]

Hi, I've been testing on 3 different MQTT instances, i can publish from the UI FLOW on my Fire Core unit. As soon as i add the subscribe to a topic the units freeze and nothing happens. Ive tried on 4 different Fire Cores i have with me and on 2 different stick C models, add do the same, as soon as you add subscribe the units boot and seem like it tries to connect to MQTT then freezes

Using firmware 1.4.2

Try removing the “Convert to str” block from label0 to see if that helps.

On second thought, after some testing I’m seeing the same thing. It doesn’t have to do with the Convert to str block in the subscribe block. It seems to hang for me in the loop when reading the temperature or humidity values from the env unit. If you put some dummy text values as strings into the map, it works fine. So I’ll continue testing to see if I can find another way to fix it. If I come up with something, I’ll post it here.
