I’m at the manufacturer right now talking about the universal compatibility and here’s the issue that we’re running into and may be a roadblock here, unfortunately.
The issue is that it appears that a lot of RF Modules (kits) use 915 MHz or 433 MHz (with the majority of them at 915 – I sent about 5 different name-brands and all ended up being 915 MHz). Since our switch will have Z-Wave inside as well as RF, there will be significant interference with 915 MHz since Z-Wave uses 908.42 MHz. The issue with 433 MHz is that the antenna is supposedly huge (so much so they were all laughing… idk lol).
They are recommending 2.4 GHz – I’m not sure how many modules out there run on 2.4 GHz.
They’re still looking into it for interference issues, but they are pretty confident if both frequencies are in the same switch, there will be interference. We asked them how it’s possible Z-Wave, ZigBee, BT and WiFi can be in the same HUB, and they said that the HUB’s are larger first of all, and second they antennas are facing different directions.
Anyway, thought I’d give an update here. I’m a little bummed as this means I have to climb up on the ladder to replace my RF modules, but I guess it is what it is.
Any thoughts or insights? I’ll admit this isn’t my forte so I’m learning too about this hardware stuff.
