ZWave Freak Out Overnight

Configuration Z-Wave
1

I have two binary sensors associated to the Gen 5 Z Wave stick. I used the AIO installer originally. Everything works perfectly during the day. I go to sleep and then nothing works. Here is the error message when I restart home assistant. I think it goes away once I reboot RPI. (To test in a second - just tested, hard reboot of RPI fixes it and sensors are recognized) The only thing I can think of is that the automation of soft reset and heal network overnight somehow breaks it. I’ll remove these automations and test it tonight.

This.

Firstly, the heal automation is no longer necessary as it happens automatically (0.20 I think). But for your (our) setup, the Soft Reset bricks the Z-Stuck until you restart. I had this exact same issue - everything was fine until I kicked of the reset in an automation then everything Z-Wave stopped.

Thanks @aimc. I deleted these from my configuration file. Surprised these are still on the wiki page.

How do you disable the soft reset? I was noticing that my zwave was dying in the middle of the night (approx 2;30 - 3:00), figured it was because of the automatic heal. Didn’t realize there was a soft reset in there as well

I actually added the automation myself. I deleted the lines from my automation yaml file. I’ll report back tonight on what happens!

I understand. Thought it was like the Autoheal that is included now
