Something I observed, maybe it’s helpful:
I had in my automation a reference to device_id to notify me about which device (see my previous posts) was the triggering one. After I introduced this update, when I was trying to ask chatGPT something from the browser (so not thhrough an assist device) I was getting as answers only:
“done”
(from the assist device it was still working fine, only from the computer was “failing”)
As a result I just put a condition to check: if device_id is valid, then the question comes from the browser and I should not make the automation have errors by trying to use device_id. If device_id is valid, then I can request the device name and area .
So … conclusion: it looks like if this autiomation is failing, then … Assist will just answer: “done” to whatever you ask … Avoid having errors in the automation
