Last month ago, I ordered some cheap BLE temperature/humidity sensors from eBay. They finally arrived last weekend, and I used an ESP32 with to get the sensor readings from them.

Initially I just wanted a sensor for the utility closet as that's where my lives, but the sensors were quite cheap so I bought a pack of 5 and put one in each room. The living room has not been comfortable this week. 😅

Hm odd, I wonder why the time axis is different between the two graphs.

@hyde well they use Bluetooth, so no cloud involved and thr BLE becon can be encrypted too with this custom firmware: (I think the stock firmware also encrypts, but I flashed the custom one so I can adjust the comfort levels and broadcast intervals).
