Multiple Languages and Voice Match Possibly Interfering with Automations

[Francispepdel]

My native language is French so I talk to my Google nest in French. My google assistant's language is set to French and I have 2 automations for different lightings in my living room (change colors and intensity of both lights at once). The starter phrase is also in French but for some reason, every time I say the phrase the automation works, changing all the lights like I want but after that, my google nest says - in French - "actually [living room light 1] isn't compatible with this functionality" although it JUST did what it was supposed to. So clearly it is compatible with this functionality. And it repeats this sentence once for every action in the automation for this single lightbulb, so 3 times total (turn on, dim, change color). I actually removed "turn on" as I realized it's not needed when setting intensity is included. So it repeats it only twice.

While trying to fix it, I added an English sentence for each automation and added English to my assistants languages. And it fixed the problem, as long I only ask in English. But it created a new problem: when both languages are set, the assistant doesn't understand when I tell it to turn on or turn off the lights in French in ANY room, including the living room. It only works in English but the automations and everything else work perfectly in both languages without the random sentence telling me it's not compatible. But as soon as I remove English from the languages, the sentence comes back.

Anybody had this problem and found a way to fix it? It used to work without any issue not long ago.

It recognizes and responds appropriately when someone else than me speaks to it in French. My girlfriend will say "Hey Google, éteins les lumières" and the lights will turn off. I have voice match activated for both of us. There's clearly something there as it responds well to her but not me 

I have 3 WiZ light bulbs and one Yeelight.

Hi Francispepdel,

Thanks for reaching out. I apologize for the inconvenience you're experiencing. We'll work together to identify the cause of the problem and find a solution. A few questions: what Nest speaker or display are we working with? When did it begin? Were there any recent changes made? Are you getting the same message using your phone’s Google Assistant? Also, what steps have you taken so far?

Since it's working when other users are doing it, try to retrain your voice and observe if it makes a difference. See the steps and the helpful article below:

1. Open the Google Home app .
2. Tap Settings Google Assistant Voice Match.
3. The app will show you all devices that support Voice Match. Tap a device to enable or disable Voice Match.
   1. If you don’t have any devices with Voice Match enabled, tap Get started and follow the in-app steps.
   2. To turn on Voice Match automatically for new devices in the same home, turn on Devices you add later.
