@fluid324 @jreed509 @kelchm Sorry for the mass tagging but I have spent an absurd amount of time problem solving this in the past week. Long story short I am not seeing the extra logging and flood of the zwave network at all with the Nortek HUSBZB usb stick.
The Zooz 700 usb stick was giving me massive problems. I tried the first firmware release for the dimmer switch and the most recent one, different settings on the switch, different number of switches connected, Home Assistant and PC controller software, even multiple Zooz 700 sticks, the ONLY thing that made it work, EVERY time, no retries or timeouts, was the Nortek stick.
LONG STORY VERSION: After a couple years of being on Hubitat I decided it was time to switch to HA. I found Hubitat to be slow when issuing lots of zwave commands to my network so I decided for a unique setup. 3 raspberry pi 3b+, running barebones HA each on it’s own floor of the house with it’s own Zooz 700 stick. A single raspberry pi 4 running my main HA instance, connecting to the Zwave sticks via zwaveJSmqtt websocket. The idea was to prevent multiple “hops” on my network for switches that were far away and hopefully speed up the network as a whole using ethernet as the main backbone with no more than a couple dozen items connected to each stick.
I flashed all 27 switches to the latest beta firmware, 6 inovelli bulbs, and 6 inovelli light strips, paired and got them all setup. I found out quickly that turning on/off all lights at once was PAINFULLY slow, and often times several zwave devices remained in the previous state. This was occuring when only controlling 3 or 4 devices at once also. I discovered this post and others from Kelchm on other forums. All 3 Zooz usb sticks were showing a flood of traffic and timeouts. The same device never had issues and sometimes my network would hang for minutes at a time on occasion and be unusable. Obviously this wasn’t going to work. I should also mention, the bulbs and light strips from Inovelli showed no problems. I could turn all 12 of JUST those on and off simultaneously without issues.
After a week of research and too many switch resets and firmware flashes I’m at least relieved that I have a “solution”. I would definitely prefer to be on a 700 series usb stick but at least the nortek is proving to be very fast (and costly solution since I need to 2 more of those now… ) I don’t know if the issue lies with Inovelli firmware or Zwave 700 having capability issues with older chips. I haven’t done a ton of research but I’ve seen posts that I thought mentioned the new Hubitat C7 was having many issues… but could be wrong. Either way I hope this helps you guys to at least get your network working reliably, happy to answer any questions if you have any.
