HVAC being set to heat by Home Assistant Cloud

I’m not even sure where to start debugging this. Twice now, my new heat pump has been set to “Heat” mode by “Home Assistant Cloud” via action “Climate: turn on”.

I logged in to my cloud account at https://account.nabucasa.com/ and was unable to find anything that references my HVAC system. How do I figure out why this is getting called?

HA cloud doesn’t make action calls.

This came from someone logged into your HA remotely or maybe voice control?

It looks like there was an Alexa voice command (“Turn on normal mode”) used at the same time it switched to heat both times, but all that voice command does is activate a scene (YAML below) that controls some lights. No reference to any HVAC stuff in the scene.

I also can’t replicate it. I’ve flipped back and forth between the scene that would have been active at the time and “Normal mode” and the thermostat has been staying on “Cool”.

Any ideas?

look at “device info” page for the thermostat.
That page will shown any automation that uses this device

Look at the Amazon App for Alexa.
There is a page that show voice command history. you can check there to see if voice command caused change. maybe it in alexa>> 3lines at bottom >> routines >>activity

Using voice commands without precise intents and device list can also give unexpected results, like “turn on great room”, which will also make the HVAC turn on, if it has “great room” as area.
