I also orderd smoke detector with wifi function. This detectors are using Tuya app. Internal wifi module is Tuya.
Test results:
1- After 2 days later, i checked my detectors with Tuya app they were "OFFLINE" !!! This is number one big faulty( or bug) but i checked batteries, both were full.
2- Using 2XAAA batteries but when batteries are low giving no low battery alarm.
3- There is no adapter input. Micro usb, mini dc jack plug input or so.
Untrustable smoke sensors that works only locally. Wifi function not working after 2 days later. Probably because of wifi communication protocols.
