Having updated the firmware to a latest release (yes I know it's not final yet) on my Enviro Urban board I found that it stopped sending to my MQTT broker.
After some digging I found in enviro/destinations/mqtt.py you have
mqtt_client.publish(f"enviro/{nickname}", reading, retain=True)
This fails as reading is not a json object.
reading
By changing it to the following
mqtt_client.publish(f"enviro/{nickname}", ujson.dumps(reading), retain=True)
and adding import ujson to the top of the script fixes it so that the reading is sent correctly to the broker.
import ujson
Side note for anyone else trying to debug MQTT: Because you have the try block written with:
except: pass
hid the error so the log just said it failed. Changing it to:
except Exception as e: print(e)
at least allowed the error to be visible and enabled me to find this.
Hey @peter-mount thanks for the pointer! Fixed in https://github.com/pimoroni/enviro/commit/871d94b0fb3174770adc2c1beea41396b3242f86
