I picked up one of these as there was a 20% off coupon on Reddit, and wanted to give my report now that I have had a chance to connect it to the hub.
When it initially paired it defaulted to the Nue Zigbee Switch driver. It did not function with that driver, so I switched to the generic Zigbee switch driver, and only one side worked.
I'm not sure what I would need to share in order for a driver to be created, or where I could go to create my own (I don't know groovy, but I do a lot of PowerShell, some .Net, and am staring to learn Python).
Can you please confirm, both the relays were working independently and you are able to control both
through physical switches. I have two wired on the network . Though both are working from HE rules, But only one endpoint is working via physical switch.
