Moved to new thread.
Long story short, we had to discontinue the LZW36 due to a dispute with our manufacturer as well as the ongoing disconnection issue that was never resolved.
We plan on recreating this switch this year with a target of starting it in Q2. It will start with Zigbee and then depending on its success, we will also do a Z-Wave version.
Instead of the RF communication, it will use either Zigbee Binding or Z-Wave Association to better improve the communication between the switch and canopy.
In addition, this switch will also be a dual switch in that it will be able to control two loads. So you should be able to use it for a bathroom fan and bathroom lights.
In other words, the base switch will be a dual switch and if you want the canopy module for a ceiling fan, you can buy that separately and Z-Wave Associate or Zigbee bind them together.
