I am palying with new Meross MS605 battery powered Presence/Lux sensor. This one is a Matter/Thread device. I configured Home Assistant as a TBR and added MS605 to the HA. My currebt setup is HA + C7 + C8Pro. C8Pro is running all Zigbee, Zwave, few LAN integrations and it is running all automations (rm rules). Matter is enabled on C7 but not on C8Pro. C7 and C8Pro are hub-meshed.
My question is - what will be the vest way to bring MS605 to the C8Pro?
The options are:
Use existing HADB Integration (running on C7) and add MS605 to the list of shared devices;
Share MS605 as a Matter Devices to C7 (nub mesh to C8Pro);
Enable Matter on C8Pro and share MS605 directly to C8Pro
Goal is to use most reliable integration of MS605 with C8Pro but not to overload C8Pro. Because C8Pro already is heavy loaded it may not be a good idea to enable Matter on C8Pro. That is why Matter is enabled on the C7 which is hub-mashed with C8Pro.
Any thoughts/ideas are very welcome.
You'd have to try really hard to overload the C-8 Pro, so enabling Matter on it is an option. However, since you are already running Matter on the C-7 connecting it there and using HubMesh to get it to the Pro is certainly a viable option and may be preferred from the organizational standpoint, i.e. bringing all Matter devices through the C-7 to isolate the traffic for debugging, etc.
I have my system split between two C8 Pros, one hosts the devices (including matter) and the other the processing. The devices are shared from the devices hub to the server hub with hub mesh and it has worked fine for years.
@thebearmay is correct, you likely do not need to split like this with the C8 Pro. My set up is like this because at one time I had a C4 that did get overloaded and split things to balance the load. I could probably put it all back together on one hub, but its more a matter of this is just what I have gotten used to and don't want to go through the motion to move everything to one hub. Overall it would probably be easier to consolidate, but I'm a creature of habit.
I am also running a C8 Pro and a C7. Just for organizational reasons I have all LAN, Internet, and Matter running on the C7 and all Z-Wave, Zigbee, and rules running on the C8 Pro. (To be precise, I have a rule or two on the C7 that only affect the C7, like one to re-initialized Chromecast devices connected via its Chromecast integration). I'm pretty sure the C8 Pro could handle all of it, and I briefly went to a single hub, but when I had some device/driver issues that spiked my C8 Pro's CPU, I decided to get move those devices over to the C7 just in case something like that crops up again.
I may have over-complicated things as I created Room Lighting apps on the C7 for the purpose of grouping WiZ bulbs together, but created the Room Lighting apps that control their behavior (activation settings per mode, on/off triggers, etc) on the C8 Pro. It results in a multi-layered setup where a RL app on the C8 Pro controls the hub mesh-linked RL activator from the C7. It could be simpler, but It makes sense to me and the hubs seem to handle it without any issues.
Having the bulbs grouped on the C7 and then controlled by the C8 also makes the RL apps on the C8 much cleaner. In my kitchen, Instead of having 9 different bulbs to set level and CT on for each hub mode in the "Activation Settings per Mode" tables, I have a single hub mesh device listed in each table, and the 9 devices are only listed on the C7. (The same thing could be achieved by using two RL apps on a single hub... one to group the devices and one to set up the actions/settings for the group). This way if I decide I want my daytime light level to be 60% instead of 50%, it is a single change, not 9 changes. I know I can set the bulbs how I want them and capture them rather than editing them one by one, but the settings table is so much easier to look at with a single entity per mode.
First off all - thank you everyone who provided a valuable feedback.
Thinking loudly about my setup, I guess the less traffic and C8Pro load will be to use already existing HADB running on C7. Now HA has a TBR capability. All Matter/Thread Devices will be added to the HA and than sheared with C8Pro via HADB + Hub Mesh. WiFi Matter Devices will be added to the C7 and shared with C8Pro via Hub Mesh. Except for the HA TBR (which I just installed) the rest is already existing setup which works just fine for over a year.
