I started here, but these instructions didn’t work out well at all.
Failed to save add-on configuration, does not match regular expression [1]$. Got {‘computers’: [{‘address’: ‘X.X.X.XX’, ‘alias’: ‘KID’S PC’, ‘credentials’: NONE’', ‘delay’: 0, ‘message’: ‘Home Assistant is shutting down this PC. This cannot be canceled. Please save your work!’}]}*
The target PC does NOT have a user password set (yet), so… how does this work? I can’t seem to get past this basic step.
I’m not 100% sure I have this right, but I got past the above issue.
You can add a button to the Home Assistant Lovelace UI by click on the three dot menu in the upper right corner > Edit Dashboard > Add Card > Button Card > as entity select your newly created switch (i.e. switch.a3_pc) > Save
I don’t see a “three dot menu” anywhere, nor anything to add a card.
Sometimes it saves without a password, sometimes it does.
I believe I’ve added the IP/MAC addresses of the two computers (trying this on my Win 11 computer first). Saved and restarted RPC Shutdown.
Now… I don’t see how to add a card to the UI. When I click on the edit tool in overview, I see the Edit Dashboard pop-up, but it only shows “raw configuration editor” and “take control” as options. Am I even in the right spot to add a card, per the instructions?
Is that going to screw anything up or make it harder to configure things? I don’t have a ton of things to add so far, just a bunch of Shelly relay/power devices and some Z-Wave smoke/CO detectors, plus TV/AVR devices. I’ve only had a HA Green for maybe a week now.
Giving that a shot. It sounds easy, but I ran into some problems with setting it up. Now I’m not sure how well taking control is working for me as n00b, trying to set up new devices that had been pretty easy to do before taking control.
