A group of Hue lights started to turn on at random intervals

Yesterday morning, a group of 3 Hue lights have started to turn on, all at the same time, at random intervals.
I first thought this could be a bug in 2025.5, but after reverting to 2025.4.4 it is still happening (so I went up again to 2025.5.1).

It is always the same 3 lights, all in the same area. I have several other Hues but these are not affected. The 3 are grouped in a helper group, but that has worked for months without issue. I disabled the group but that did not change anything.

In the logbook, I get the following messages, not really helpful to me:

Lumière canapé  turned on triggered by state of Home Assistant  changed to 10 May 2025, 11:43
Lumière commode salon   turned on triggered by state of Home Assistant  changed to 10 May 2025, 11:43
Lumière fenêtres salon  turned on triggered by state of Home Assistant  changed to 10 May 2025, 11:43

At the same moment, the following line comes up in the logs:

2025-05-10 11:43:34.383 INFO (MainThread) [homeassistant.helpers.intent] Triggering intent handler <OnOffIntentHandler - HassTurnOn>

The only changes I did were to update couple of HACS add-ons to their latest version. I now have even deleted those addons by no difference.
Other that that, I did not change anything to the configuration since at least 2-3 weeks.
For info, I manage 95% of my automations outside HA in Node-RED. I checked and these actions were definitely not caused by a Node-RED flow.

I have no clue were to look at. Any idea where to start?

Are you using Amazon Alexa with Home Assistant? If yes, please disable Alexa’s Hunches feature. This is Amazon’s feature that tries to figure out your usage patterns and automatically create Alexa Routines that anticipate your needs. It has caused issues for numerous users in the past on multiple home automation platforms.

Hi,

Actually, I completely disabled Alexa to rule out issues there, but the problem persists…
That being said, what are those Alexa Hunches?

Pretty sure I already answered that question

Here is some more information on Hunches
