I purchased 7 Zooz Zen26 to use with my new C7 as well. Pairing worked... after excluding and including a bunch of times, not the greatest experience. Anyway, I got them paired, the built in driver works for them, but if you want/need the additional options you need to download a custom advanced driver.
The custom advanced driver does not work with the Zen26. I'm not able to use any of the buttons in the web interface for the device to turn it off/on, etc... however it does report the state of on/off if I manually turn the switch on/off.
I'm beginning to think this is a C7 + custom driver issue vs. just the driver.
Anyone else having issues with Zen26 and the new C7?
