Zwave is some kind of open source. I’m not all that familiar, it competes with Zigbee. I need something that is powered by a battery pack that lasts a few months at least, and that is controlled by zwave controller and turns a led light switch on and off. The tea lights already have a battery pack, so I just need on off. I don’t know how to post images, but in the zwave me Arduino link there’s a pin out drawing. I can power that thing with a battery pack I think it said 3v. I’m guessing two of those other pins are what i need to connect to the light on off switch.
