I have an outdoor temperature sensor which, when looking at the ESPHome Logs seems to send its status to HA without any issue. I use the native API (not MQTT).
But HA reports the device as “Unavailable” and there are no duplicate devices I can find which have been recreated instead. Any idea what could be going on or how to debug it?
Can you please copy and paste these beginning from rebooting the device.
Thanks for the prompt reply

This is how the device now shows in HA. It used to work fine until I upgraded HA a few days ago, first to 1.5.x (Can’t remember which) and now 1.6.1.
Try removing the device from Home Assistant and re-adding it manually.
If that’s the logs from boot, HA doesn’t make a connection. Similar section from my logs:

Note the api.connection line. Try @tom_l’s suggestion (here’s how) first.
Thank you both - much appreciated and will revert when I have done so.
@tom_l - I’ve tried what you suggested. The new devices (different name) shows up in Home Assistant but the Sensor Entities are still listed as “Unavailable”
@Troon - the API Connection line does not seem to be there either on the new device.
Are there any errors in the log about it not having a unique id?
Apologies but I don’t think I ever had an error about not having a UniqueID? Is that in the device log or somewhere else?

There is no reference to that sensor in that log…
And you definitely have this in your ESP config:

typo ?

Yes obviously that’s a typo - otherwise I would not receive the logs 
Does anyone have any further thoughts on this? The sensor randomly seems to start working/stop working. I can always retrieve the logs and upload the firmware so the wifi communication seems to work fine.
But the HA-API comms seems to fail regularly and unpredictably and when that happens the sensor shows as “Unavailable” in-home assistant?
Happy to spend some time debugging further but don’t know where to start.
Hi, were you able to get your status working again?
I’ve got a new esp32 installed, while it does work, epshome is still giving me unknown status
I believe it was a hardware failure. I replaced the unit and it now worked for months.
