a better choice might be Sylvania 73743a which is standard? device type “Zigbee Button” - I think you get battery monitoring and 2 buttons combination of press, hold etc.
Battery Operated 3 Toggle Switch for wallmount or table top use (SmartenIT ZBWS3B), Long Install FAQ
Agreed. It’s only two buttons instead of three, but it now has a stock DTH and would be a much easier install.
Will this work with the classic app, it seems like it should,
Sylvania Smart Home 74099 Sylvania LIGHTIFY Smart Switch 8 Functions/ 4 Buttons, White
Some people have been able to get the European version of that to work, but people with US version have only been able to get the two buttons on the left side to work. ( they are the same frequency, but the firmware is different.) Much discussion and lots of details in the following thread:
People have been working on this for over a year but the short answer is that the US version just doesn’t work with smartthings at the present time.
Please take any further discussion of this device to the thread I’ve just linked to, as it’s way off topic for the thread we are in now. Thanks.
