Is there any 3 phase wifi power meter for 3x 400V system supported by eWelink?
Thank you for advice

As far as I know, ewelink does not have such a model. I have seen with TUYA
It’s true, but want one application center, in my case is eWelink.
Maybe it is possible to connect tuya to sonoff iHost ?
ooo no no with iHost I don’t believe you connect TUYA. iHost has so many problems with ewelink that I can’t afford to pay attention to a third party connection.
Hello.
I’m looking for a device that I can connect to 3 phases ideally via coil and LAN.
Sonoff POWCT only supports one phase.
Are you considering a device that would meet this? The competition has had it for a long time.
I currently have 17 Sonoff devices and I also use iHost.
Thank you
Peter

You can install three single-phase meters, and then you’ll have to add up the readings of all three. This is easily done with HA, or you can do it from the eWeLink energy configuration menu by adding the readings of all three meters.
I think you might have to bodge it. I suspect the cost of a chip and the small market make a three phase power meters commercially unviable. I’d just look up a chip that does it and wire it to an ESP32C3 and send it over MQTT to an iHost or if you have Zigbee and no iHost I’d go for an ESP32C6 and check if there is a power meter profile in the espressif zigbee arduino github and eWelink support power meters over zigbee if they meet the standards.
