CO2 sensor can't send data to Home Assistant. #3464

Closed kevinblo closed 1 year ago

kevinblo commented 1 year ago

The problem

Every few days, the HA stops receiving data from the sensor. Prior to this, the sensor worked for more than a year without failures. At the same time, these data are visible in the asphome logs. It helps to disconnect the sensor from the power supply and connect it back. Or delete and add this sensor to HA again.

Check the HA logs for why it's not able to connect to the device.
