Suddenly device can't be controlled via HS3, but polls and reads fine

[neuro]

I've been trying to setup the Aeotec multisensor to turn on my GoControl / Nortek lights, and everything was working fine last night. I move, and the lights come on.

As of this morning, I can't control the lights anymore. I can poll it fine, the connectivity is fine, HS3 scans it and sees it, etc. I've removed the node and readded it without errors. Logs show everything is OK.

There doesn't seem to be a problem communicating with the switch, just that it won't respond to any commands via the web interface.

Can anyone suggest things I can investigate?

If anyone is wondering, I updated my HS install and rebooted.

It worked semi fine after that until I did a network scan and new nodes popped up.
