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?

Especially that the firmware also works not like the last one.
I'm not sure if new firmware restore Pow R2 at functionality of 2.8.0 version, but support tell me "we will soon release a new firmware, please wait". Please open a support ticket from ewelink app...support reply shortly...

Support reply me strange request at last "when new firmware???"I don't know, for me developer team don't work at this trouble Or this trouble are wanted by Itead for reduce data transfer from server or database. I'm not happy!!!Community of open source project are more efficiently. @SeByDocKy sometimes help request by app request to resend many time but work ;-)))

Ok if if within 2 weeks, the problem is not solved, I will install ESPhome instead ...


Shame Itead ....For sure I will avoid their product in futur....

Other pruduct not have app+HD interface but you must install server like domotikz or similar...ewelink is a simply and cheap solution...I'm waiting for solution!!! Go Itead publish new firmware!!!

More than 2 month waiting a "little fix". This is not just a "waiting for solution", this is a torture and a huge lack of respect with sonoff users

New ewelink!!! New firmware???
I noticed that the problem is with the application when it comes to pow r2. You need to remove the applications from memory later start and everything works great but until about 40 seconds. no application refreshing. They fucked up with the lack of refreshing data from r2

Yes ... data are refreshed like crazy the first 40-1min then .... silence ....  Can be also a problem from their cloud server ....
