Very Good

Great product, modified with esphome works great.

It keeps track of all the consumption of the washing machine.

Great after the update

SONOFF POW R2 proves to be an excellent product, distinct contacts and accurate measurement of the electric current.
They crashed a few times on the first few uses and I was forced to update the firmware, but then I haven't encountered any more problems.
I think they should study to make it smaller without sacrificing quality.

Great product and build quality. Loved it.

Super produit, marche très bien

Très bon produit, je contrôle un chauffe eau avec. Je l'ai flashé avec esphome pour qu'il s'intègre bien dans mon installation home assistant.
Dommage que le cache bornier ne soit pas un peu plus englobant, et qu'il ne cache pas aussi les entrés de cables.
Mais pour le reste c'est parfait.

Very good. Only minor gripes

Just installed two of these. I have several of the R1 and R2 to compare this newer one to. The wire attachment is much improved. Previously it could be a PITA. Also the aerial seems improved. Previous versions would disconnect even though a phone worked. These seem fine so far. I think they’ve also added push notifications for when the usage goes above a certain amount (daily or monthly).
The two things which are negatives;
1) No earth anymore so you have to either leave the earth wire intact or use a connector.
2) No physical grab of the wire separate to the connection anymore.
Given that these are nice looking and you’re less likely to want to put them in a box having to use an outer box seems a mistake. I like the grab attachment though. It means you can stick the grabber into the box and then when wiring is complete click the device into the grabber.

Excellent device. Bought a couple. Have lots of the R1 Version. The R2 has better connectors for wiring up the device, looks a bit sleeker, and is easier to install on the wall with the snap in mounting. I use ewelink and Alexa to control these, and both work perfectly with the R1 & R2 devices. The power usage reporting for the R2 seems to be a step up on the R1 also, but I haven't spent much time playing with that yet.
