Smart home is not about just turn on/off lights remotely. It's about do it automatically/reponding to other interactions.

i.e, when sunlight is out (in HA, you can get sunset triggers), and when there are people present in living room, turn on living room lights.

Or "when the only occupant opens the front door and drops off the network, turn off all lights, arm the alarm, turn off the stereo, and yell at me if the cooktop is drawing power".

> and yell at me if the cooktop is drawing power

For standard power outlets I have "smart plugs" that measure the power draw, are there ones that support 40A/240V appliances?

I'm a zigbee fan, mostly because there's such a wide variety of devices.

I almost exlusively use zigbee2mqtt [0] reference to find devices that suit me. Searching for `meter` gives a lot of options, you'd have to do more investigation to find something that supported 40A, but my guess would be that a clamp meter is likely your best option.

It's also possible that you could use one of the DIN rail options in your fusebox, but I haven't looked at the current ratings.

You're gonna need power meters for that. E.g. check out the Shelly *EM series.

I wrote a little script for my homebrew ESPHome-controlled CW/WW LED strip to automatically control color temperature based on if and where the sun is in the sky. Warm-only when the sun is down, mix of warm and cool when the sun is up with peak coolness at solar noon.
