Standard POW can only show energy used in kWh or it has option like R2 to set price per kWh and show total cost per day/month?
For my freezer I found a solution : I soldered a wire on the relay contact. So I have always power on.
To make the SonOff measuring it must be on. So I added 8 timers, the maximum, to switch it each three hours on.
As soon as the official modification arrives I'll take it out.
thanks wimb for u solution, but if you set the relay always close. The security options (over consumption, over voltage) and timers do not help us at all. since, they can not cut the output voltage at any time.
some time ago I opened a ticket for this topic,
This past week they replied saying: ".. We will launch a new firmware for POW R2 within this month with this option"
all this was just before the release of firmware version 2.7.0 and this version still does not bring any solution to our problem.
I'm waiting for the solution to come out at once.
Here you can see the version and the power on state
Sonoff POW R2 updated to 2.7.0. Still no such option.
you have had the same problem as me, even if you update the POW R.2, new options do not appear.
The solution is easy. You must also update the eWeLink app on your device.
problem solved with the 2.7.0 update.
Do not forget to also update the app so that the power state options appear and can be used.
I have newest ewelink 3.5.1 from play store:
That is great news, I am taking out the POW R2s I have out of their boxes and trying now. I hope I can see the update.
No option for me :(
My app in on version 3.5.1.
