Why cant I connect to the alarm using 5GHz but use 2.4GHz?
Tuya Smart related products only support 2.4GHz WiFi now, so please dont use 5GHz to connect it. If you encounter difficulties during the connection process, you can consult the 24-hour after-sales customer-service at any time.
Can the detector be mounted using a magnet sheet?
This detector is heavy, please do not use the magnet piece to install.
Can I hook up more then one on phone?
Sure.
Is this hard wired?
No, its battery-powered.
I have any questions about the TUYA APP that I cant solve, what should I do?
