I installed my esp32 with a bluetooth proxy, but previously, I had installed ESPrecense on this esp32 device. After installation, I added it (manually) on the integrations page in Home Assistant (Add integration, ESPHome, enter IP address).
Now, the “Device info” says it’s ‘bluetooth-proxy by esphome’, but when I click that device, I see ESPrecense sensors and entities. How is this possible, since this firmware should have been wiped?
To my surprise I now also have a “iBeacon tracker” on my integrations page.
I have no clue what’s going on here. I also used a wipe function to erase the firmware. I thought maybe Home Assistant uses information from a previous discovery, based on mac address and/or IP address?
You have to remove integration configuration for previous firmware. The best is remove both old and new and then add new. That should fix ghost entities.
In HA open Settings / Devices and Services / Integration.
Find ESPHome integration and there is a list of all ESPHome integration.
Open one that does not exist any more.
Click on three vertical dots menu.
Click Delete.
I did that several times, but then when I added the ESPHome integration again, the entities were all back again.
But, I also found a button “Delete from MQTT”. After I pressed that, all those ghost entities were gone. It seems to be OK now, and the bluetooth proxy seems to be working as well.
