I have a MQTT sensor that gets data from a Watchman oil tank sender.
After a restart of HA, I always get errors on the dashboard ‘Entity is non-numeric: sensor_oil_tank_gauge_depth’.
Until a new reading is received via MQTT, this only happens a couple of times a day.
Its odd though, as on the settings page for the sensor, it simply says ‘Oil-Tank Gauge Depth: Unknown’. Yet on any dashboard it gives the error.
Is there anything I can do to work around this?
