@rpimag I gave MicroPython a whirl (as CircuitPython doesn't support Bluetooth on the the Pico W) and wrote questionable code that scans BLE for Inkbird ITH-11-B Thermo-Hygrometers every few minutes and relays the data (humidity/temperature/battery level/rssi/MAC address) to my MQTT server over WiFi.
I then have another script which saves the data from MQTT and graphs using RRDtool.
