As detailed in this thread from last year, I've been running 2 hubs at my house since August last year. Newer C-7 hub is in the main house, connected to everything in the house, integrated with Lutron Caseta, and has all of the rules/logic.
My old C-4 hub has been in my detached shop. I have a couple of z-wave garage door openers, a thermostat, zigbee lock, a few motion sensors, and my pool equiment - which is two zigbee relay boards - paired and shared to Hub Mesh. I don't have any rules or anything running on the C-4...all of the "smarts" are on the C-7.
Both hubs are on a Orbi mesh network. The main C-7 hub is connected to the main Orbi router. The C-4 hub is connected to an Orbi satellite in the shop. I have good connection and speed status on the Orbi network, according to the Orbi app.
Occasionally, when I try to connect to the C-4 hub, I get timeout errors, and it will take 20-30 seconds to connect and successfully reload the UI page. The Hub Mesh also goes offline occasionally. Of the two zigbee relay boards I have paired to the C-4, one seems to work flawlessly, and one seems to miss commands maybe 10-20% of the time. There's also been once or twice where the hub has been completely unresponsive, to where I've had to unplug/plug it to reboot it.
So I guess to summarize...I'm trying to solve occasional slow or non-responsiveness (which I supposed could be due to the wireless mesh, but I have good signal...so....I dunno...), and occasional missed zigbee commands on one of two relay boards that sit within inches of each other.
First question - is there any difference in zigbee capability between C-4 and C-7 hubs?
Second - has anyone else seen slow or non-responsiveness out of the older C-4 hubs? I'm assuming whatever causes this is also what causes the Hub Mesh to go offline occasionally, but I don't have anything to back up a root cause or correlation between the two.
Anyway - just looking for opinions here...if I do pick up another C-7 I'd like to do it while it's on sale for Memorial Day right now. But also don't want to drop $100 to end up in the same position I'm in right now.
