Issues with SensorPush temperature sensors (BLE)

Hardware
1

I have been running the SensorPush temp and humidity sensors for a while now. But sometimes (I haven’t been able to correlate why this is happening), I get erratic readings. Note that I have 3 bluetooth dongles spread around the house listening for BLE – not sure if that’s related.
Usually after some time, the glitches stop. But it’s really annoying since I drive a thermostat with these readings … This is what I see as an example.

Note that the SensorPush app has a clean temperature signal, so I doubt it’s the sensor. Other values from the sensor (humidity, pressure) all fluctuate / glitch similarly.

Replying to myself here, just in case anyone else runs into this. It appears that multiple USB or USB combined with internal bluetooth dongles cause these issues. I’ve observed it with the SensorPush devices, but also with Govee temp sensors. I disconnected/disabled 2 of my 3 Bluetooth dongles and the problem disappeared. I’m going to try to bring up a few ESP32 BLE proxies to see if that causes the same issue.
