ESPHome DS18B20 sensors not appearing as entities

ratsepa · May 19, 2022, 10:40am

I see my Dallas sensors in ESPHome logs sending values, but those sensors are not visible to HA as entities?
I have made every restart and reinstall, nothing helps.

Answering myself
Deleted this ESPHome device from HA,
restarted and after that discovered ESPHome device have also 4 entities

For anyone with the same issue above - I can confirm this solution worked for me as well.

I have a Wemos d1 mini, with a pressure sensore attached for a pool pump pressure monitor.

Flashed the D1 with ESPHome, created the device in ESPHome, and connecting to the device via ESPHome the logs showed connection and data from the sensor streaming.

Jump into the dashboard device to set up a card, select the entity, the entity appears but no data.

Followed the solution from ratsepa as above and bingo- its live.

Thansk for posting your solution ratsepa, It was doing my head in.

Jarrod.
