Heavy duty z-wave powerplug

Hello all,
I had my tumbledryer connected with Domoticz through a greenwave powerplug to check if it is ready and to measure the energy amount. I bought myself a new tumbledryer and the greenwave powerplug is overloaded..

Has someone experience with a powerplug which can handle 16 amps. The neo coolcam powerplug can handle up to 13 Amp, which is not enough. I want it to be z-wave because of the energy measurements.

Anyone?

Regards, Hans

Check out:
https://aeotec.com/z-wave-outlet-socket for 15A
and
https://aeotec.com/outdoor-z-wave-switch for 40A

I do not have any experience with these, i need an 16A but i am going to try it with Sonoff POW 16 A (which is not ZWave but WiFi) because of the price and it also supports power consumption.

If you don't want to actually switch the dryer on/off and merely want to know the current consumption, you can use inductive current sensing with something like this which does not interrupt the circuit.

I have a 4-channel one in my fuseboard to measure the current going to the groups for washer, dryer, oven and dishwasher. Has an i2c interface that works directly with rpi. Manufacturer is ncd.io

Here's what the fuseboard module looks like with the 4 browns from the heavy groups looped through. At the bottom you see a pi-zero-w that runs a small python script and nothing else. It updates 4 x watt-meters in Domoticz and also 4x switches for on/off status indication. I use it with the Logitech Media Server alert perl script that I wrote about in the wiki to play audio messages when the washer or dryer finish. Really cool !
