Recently added the Monoprice Dual Relay and it works very well. The only issue is that it shows up in the list of devices as one item and there is no way label each individual action inside that item, just switch 1 and switch 2. Have not tested with scenes, rules etc.
Installed Aeon Labs RGB LED bulb as well. Was tricky to pair but it works. But it works only as a dimmer bulb no RGB at this point. I tried selecting other which makes it a multi level switch. There was no option for the RGB bulb. That said it works just fine as a normal dimmable bulb. A note, it is massive, much larger than standard LEDs and the GE Link LEDs. It may not fit in your fixture, there is even a warning on the package. It has not been tested with rules, scenes etc.
I installed the Aeon Labs Doorbell. It connected as a siren. I can activate it from the LCD and it rings twice. I can see it active at that time. However, when pressing the doorbell itself, I do not receive the activation on the LCD or my phone. It does not show up as active. The range is terrible, like 10 feet was difficult through my exterior door and I had to move it several times. I selected a standard siren noise but there are several choices and you can upload your own. It constantly shows as ringing on my app. As of now out of a very expensive, mediocre wireless doorbell. Have not tested with rules and scenes etc.
I will update to newest firmware this evening but don't expect those issues to change. I'm not terribly upset since these are new items and I got them both used through Amazon at decent discounts. Will keep them for now.
