Can the audible alarm be disabled?

It has high, medium and low volume settings but I do not think it can be completely silenced. You can adjust the duration down to only 10 seconds. This is a brand new product that will get some enhancements by way of firmware updates. That is a good idea to be able to completely disable it, so I will submit that idea to engineering.

Can we add more than one device to the hub ? I have to freezers in the same area

I don't know what the limit is, but I have two motion detectors and one power monitor on the same hub.

If wifi is alive and only power of hub is out, can trigger this alarm? If power of hub is on and only wifi is dead, can trigger this alarm?

The audible alarm will activate if power to it is interrupted. If the hub is out/offline, you'll receive an email or text notification (per your settings) in half an hour. If WiFi is down, you will not get an immediate notification on the app, since the app requires an internet connection to the device via the hub. But you will get an indication in the app that your device is offline. And if both WiFi and power is out, you'll get that notification in half an hour. It is worth pointing out the PFA can be paired to other alarms or relays, plugs, etcetera, to cause a remote alarm or device action, if you need that. Enjoy! Eric with YoSmart

What does it mean if the led to the left of "set" button is blinking green? yesterday it was solid. in the app it seems to be fine.

Solid green is what it’s supposed to be. I believe when it’s blinking it’s telling you it’s not connected. Mine has been solid green and has been working perfectly fine
