Inkbird IBT-26S 5G - any luck?

not really I think




I think the conclusion is that the most advanced inkbird sucks.

I don’t think this is actually the IBT-26S, but a Tuya device, which somehow does have the same BT MAC address as the IBT-26S WiFi MAC - strange indeed.

But the previous messages from "id": "F4:60:77:A5:F3:BB" were definitely from the IBT-26S, as it also had it’s advertising name in some of them

For easily being able to decode temperatures from its (non-existant) advertising data, I agree :frowning:

This one is really funny… I only registered to post this.

There seem to be two BLE chips on the device. I guess they just piggybacked the WIFI feature with a Tuya device? Anyone here wants to disassemble one?

Anyway, I used the following config to get a reading in HA based on an esphome esp32 gateway.
