Have read through a few threads that seem to have the same issue from a while ago, but nothing recent and they all mention an older version of HA.
I have the Xiaomi BLE temperature sensor and have configured as per the instructions Mitemp_bt integration
After a couple of hours maximum the sensors do not update, and only begin working again after a restart of HA.
I have moved the sensor right next to the raspberry pi and still the same issue.
Anyone have any avenues to go down to fix?
