I’m still cutting my teeth on HA and have some wifi devices connected and automated, now its time to integrate other protocols.
The thermostat I like talks ZWave, the deadbolts I like talk Thread over Matter, and I want to incorporate some Shelly relays and in bulk seems like the zigbee variant is most affordable. At some point I want to incorporate motion and presence sensors but haven’t decided on which ones yet.
My understanding is I can integrate ZWave with a ZWA-2 so i ordered that, and the new ZBT-2 can talk both Zigbee and Thread but only one protocol at a time. Can I run two of those and the zwa2 all off the same HA VM? I know ZWave is 800Mhz and Zigbee and Thread are up at 2.4 GHz, so what are the odds that running all that RF out of my utility room wont conflict and have issues?
Am I making this too complex? I don’t have another thread border router in my house, my alexa show is ~5years old and I don’t have any new assistant devices like that or an apple tv.
Will the matter and zb zbt-2 radios collide because they use the same spectrum slice? Do you have to adjust channels or something similar to de conflict wifi routers?
I’m not expert, but sure it is possible that there could be collision/interference with anything that uses a shared rf spectrum.
how bad that will affect things will be completely dependent on the local rf environment.
Personally I am running 2 bluetooth dongles, zigbee, thread, zwave, and a wifi AP in the same room and have not experienced any rf attributable issues.
They can and it is recommended to find different non-overlapping channels for the different radios.
Remember that multiPAN with Zigbee and Thread will always run the same frequency and therefore sort of interfere with each other.
Zigbee and Thread use same channel to frequency relation.
Also remember that these are mesh networks and mesh networks gets better, strong and more resilient with the number of devices.
Spreading your devices out over three different networks might be lowering the quality of all the networks, unless you go nuts and like 50 or more devices in to each network.
