This is my first foray into Z-Wave. I am running Home Assistant (2023.6.3) Supervised (2023.06.4) on Debian 11 and I have the 500 Series GoControl HUSBZB-1 and one Ecolink ZWAVE Plus Smart Switch, a battery powered switch faceplate that mounts on top of a dumb single rocker wall switch.

It seemed to work fine for the first few days and then it started getting reported as a dead node at random times after 10, 12, or 20, etc. hours. It will stay dead until I manually flip the switch, at which point it will instantly show up as live again in HA.

As if that wasn’t bad enough, it now almost instantly goes dead every time I turn it off and will only become live again if I manually flip the switch to on.

Turn off through HA
    22:58:21.344Z [Node 004] did not respond after 1/3 attempts. Scheduling next try in 500 ms.
    22:58:25.353Z [Node 004] did not respond after 2/3 attempts. Scheduling next try in 500 ms.
    22:58:29.332Z [Node 004] The node did not respond after 3 attempts, it is presumed dead
    22:58:29.332Z [Node 004] The node is now dead.
Turn on manually
    23:01:32.874Z [Node 004] The node is now alive.

I have used both HA Z-Wave JS and also Z-Wave JS UI. I have excluded the node and redone setup from scratch for both. The switch is about 10 feet away from the controller and the controller is connected to the computer using an extension cable (also tried without an extension cable)

It seems weird that it only goes dead when the switch is physically in the “off” position, as if it goes to sleep, which seems logical, but then HA cannot wake it up again. Ping does not fix it. Heal does not fix it.

I’m currently back using Z-Wave JS but when I was using Z-Wave JS UI, I looked at some of the debug info for the switch and it had a parameter (I forgot the name) saying that it periodically woke up every 1000ms to check for network activity. Maybe that isn’t working correctly or HA or my controller can’t figure out how to work with that.

Does anyone have any suggestions or experience with both of these devices used together? Do I need a better Z-Wave controller? Do I need a better switch (I’m very limited in my choices here since the wiring in my house is not very good and I do not have a neutral wire)?
