Via the HA Tuya integration, I can switch it on and off, but I cannot get any energy readings out of it, while the Smart-Life app can read Voltage, current, power, and also display hystoric power data, per day and per month.
Any ideas on how to pull this data in HA ?
Unfortunately not.
I am thinking of buying a Wifi kWh meter from Homewizard.
They recently add an api that can be read via HA, and on top of that, it is also mid certified, so you can also use it for accurate measurements, so you can even use it for official billing purposes.
