Hi @Wayne-TP, thanks for the reply.

So besides the hub's sub-devices going offline, the hub itself also goes offline. When this happens, the hub has a red solid light, which, from some reading online, seems to indicate an issue with Startup or Connection Problems. The only way to fix it is by turning the power off and on again. When it is in this state, I can't make it ring, view the doorbell camera or use any of my smart switches.

Thanks

 Hi  @Wayne-TP, it has been connected via wireless. I have only just gotten around to getting it wired (took some time). I'm monitoring it now and will update again when i have something. Thanks

 Just on this, I spent enough time with support to figure out a solution where hub connected devices just stop working until a hard reset of the hub. Then it'll work again for a day or so and require a reboot again. 

I've got two h200s and tried to split the load between to the two of them. Only have two sensors and three s200 switches. 

It worked fine for the past 5-6 months and the problem has come back again. 

I've had enough with this and moving to ZigBee compatible sensors and switches. 

  @SaleemK Dammm, that's a real shame, because the issue you are having sounds like mine too. Hard wiring it has helped, but has just made the issue happen less; it still happens though. It is a real shame. I wonder if the H500 suffers from the same issue? But it is a lot of money to spend just to see it happen again if it does.
