Of course you could use rpi as gateway, but as personal advice I'd suggest to get some mini pro as sensor nodes and keep the Uno as the gateway or the prototype platform. The most flexible solution would be to make an mqtt ethernet gateway and use rpi as mqtt broker and controller with openhab or whatever else you like, since the mqtt in the middle allows also to have multiple controllers. I also wanted to try openhab and tried openhabian but it turned out to be too complicated, so I moved to domoticz and it was much easier to put things together.
@Pascal-JEANPIERRE It is awesome you are trying to teach your students about automation, but PLEASE if you are going to teach it using arduino etc and cant even change a #define statement(that is located at the top of a file written in plain english) take a simple arduino course of some sort or a C programming course.
this stuff is super simple to learn and a few evening of effort on your end will go very far to teach properly.
@timmy If you are referring to the Google assistant, you need to open the app, tap the compass icon in the Explore section, enter Settings, scroll to Services, tap Home Control, and scroll until you find the selection for your lights. But I'm not even sure what you are talking about, I might be giving you the wrong directions here.
@rmh said in EV Charger (type 2) with RESTful API and Wifi recommendations?:
@รอเร-อ btw Normal single phase type 2 charging on an EV is 32a = 7 Kw. If your ev can charge at 22Kw, then it will need a 3 phase supply. OpenEVSE can do this but you will need to put a 3 phase contactor in it.
Thanks a lot. That seems to be exactly what I'm looking for. I didn't order the kit though. I ordered the EmonEVSE WiFi Connected EV Charging Station IEC 60947-5 (Type-2)
I'm very excited to get started. Ohh... I'll need an EV too... ha ha
