Sonoff POW R2 Energy monitor drops to 0 on new update 3.3

I bought 6 sonoff devices and I tried upgrading to 3.3.0 on one device. The energy monitor most of the time doesn't work. It's like stuck to 0 Watt or whatever the last number is there.  Sometimes it just drops to 0 Watt even when the AC is working. 


I'm not upgrading the other devices. How can I revert to previous firmware to fix this?

I didn't face any issue while streaming movies. If you are a movies love then Netflix app is the best way to watch it for free.

Thank you.

Even I has upgraded to the latest version but I don't face any issues during the Creditone

I wanna put a sonoff pow r2 on my air conditioner do measure the power consumed. But here in my house, 220v is provided by two-phase lines (2 hots). Do the SONOFF Pow r2 works that way. Netflix Mod Apk

Hey people download best android [url=https://get-9apps.com/index/]apps[/url] and games from [url=https://get-9apps.com/download/]9apps[/url], also watch [url=https://get-cartoonhd.com]movies[/url] for free

It was a really amazing experience on this site. I always download Mod apk from Apkmodpro

The values (W,A) show a maximum of 1 minute, then they freeze.

When the appliance is connected and switched on, first shows the values,

but when I turn it off and on again, the values are no longer updated.

Turning the device off and on works great.

Firmware 2.9.0 and higher very bad! 

Firmware 2.8.0 worked!!
