So my Monoprice / Zooz 4 in 1 sensor was stuck reading the same temperature. I tried rebooting, complete shutdowns etc with no change. I had the idea to try and remove the node, but could not successfully remove the node by using the tools in the Z-Wave manager in Hassio.
I decided to do a new install on a separate SD card to see if the device was faulty or if it was a config issue. After playing around with a new install of Hassio, I could not communicate with the sensor as I was getting invalid certificate warnings etc. so I decided to copy over certificates, restore setting from my previous install, nothing worked.
In the end I could still not communicate with the sensor so I decided to reboot into my old install. Hmm, locked out and could not get back in. Well it is a good opportunity to do a fresh install and see what new things I can learn from the process.
So after the new install and getting things running again, still no luck with the sensor, but I did not have a Failed node along with the new node I setup. I did finally find a nugget of information that finally helped me. Removed my failed node, and I was back to using my sensor for controlling the fans in my house, yeah!
You might have to update state manual as described in the last section here: https://www.home-assistant.io/docs/z-wave/adding/ 34
- Go to the States menu under Developer tools in the Home Assistant frontend
- Click on the name of the zwave. entity you want to remove
- At the top, edit the JSON attributes to replace false with true for “is_failed”: false, so that it reads “is_failed”: true,
- Click Set State
- Go to the Z-Wave control panel in the Home Assistant frontend
- Click the Remove Failed Node button in the Z-Wave Network Management card
- The device will now be removed, but that won’t show until you restart Home Assistant
I did learn a lot more about Home Assistant / Hassio during this process. Always good to have situations where things don’t work. Yes it can be frustrating, but generally a good learning opportunity 🙂
Here is a copy of the Zooz ZSE40 VER. 2.0 Manual. The Monoprice manual did not have the proper reset instructions.
