Hello all
I am about to install a charger for my EV and want to have it switchable by OH (disconnect power, when I am not at home).
Since my Fibaro Switches are limited to 8A, I need another switch, that supports 32A.
Can any of you recommend a CE certified device (zwave preferred) or a workaround for that?
Thanks.
I’m pretty sure you will not find a device which supports more than 16A directly, but of course you can use a high power contactor to switch 32A and switch the control voltage with whatever you want… 
Hi,
I think you should be careful!
Depending on your electrical consumers, the sustained contact current has to be calculated (if you have inductive loads, the starting current can sometimes be 3 times more than the nominal).
As @Udo_Hartmann said, I don’t think you will find smart relays over 16A rating. You can always use what you have (the 8A relay) as an intermediate relay for a bigger current rated relay (let’s call it dumb powerful relay), by energizing the coil of the big one through the switching of the small relay.

Lower current controls such as 30/40 amps are not hard to find and are not so expensive. The higher current contactors get to be a lot more expensive. I want to install a Tesla wall connector on a 90 amp circuit allowing up to 72 amps charging current. Relays at this current rating are rather expensive, the lowest price I’ve found is $145 with a 120VAC coil so it still requires another switch to control it if using something like a ESP8266 for control.
Just to throw my hat into the ring…
Surely there must be a control line or inhibit function on the charger?
Please don’t tell me that these cars hook up to a live connection?
I do know that the Nissan Leaf can be given a time to be fully charged by, or be aware of lower price charging times.
Have a search. I recently answered almost the exact same question…
Doesn’t openHAB provide a tesla binding?
Really? A Tesla binding??? That would be pretty awesome. I’ve seen a few apps that can do things with Tesla cars, but they require you to give log in information to third parties. I assume an OpenHAB binding would not work that way? You can maintain security without trusting third parties?
