Meross presence automations stopped working

[DaveClee]

I’ve had a Meross presence sensor set up for a little while, running an automation for a strip light, which lights up the reveal around the skylight when the room is occupied. It’s been faultless. 
it’s now completely stopped working - the sensor is brand new and working as expected - in the native app I can see the presence detection. The light also works fine, voice command or from the home app. The automation has just stopped automatically triggering - if I press play on the automation in the home App it works fine. 

Any ideas? It’s as frustrating as anything when it was fine last week and nothing has changed!

Hi @DaveClee,

Thank you for posting in the community! I understand the issue you're facing with your Meross Presence Sensor. It’s frustrating that it was working perfectly and suddenly stopped activating automatically, especially since the sensor is new. To help narrow this down, I appreciate you verifying that the automation still works in the native app, via voice commands, and manually within the Google Home app. I’m glad to help you get this back to working automatically. 

To help me identify the root cause of the issue, I have a few questions for you: 

• Is the Google Home app up to date?
• What is the Google Home app version? 
• Are you using an Android or iOS device to control the Google Home app? 
• Are you using the latest version of the Meross app? 
• Could you confirm if your mobile device is updated to the latest operating system version?
• Is the “Activate Routine” toggle enabled in the Google Home app? You can check this by going to the Routine editor and verifying that the toggle is switched on.
• Have you tried any troubleshooting steps previously? If so, can you list them? 

I look forward to your reply so I can assist you further.

Best regards,

Stephanie

Hi @StephanieQ,

Thank you, so, yes, everything is up to date. I am using iOS 26.2.1 on iPhone. 
my Google home version is 4.8.50, the Meross app is up to date too (3.39.0). 
The routines are also set to active. 

So far, I have reset the sensor, unlinked and relinked Meross to Google home. I deleted and recreated the automations too. Originally they were set with time parameters (only to activate when the sun had set), however I removed the times as I had read there had been some issues with automations that included time triggers. 
I also used Gemini to script them for me, however none on this has made any difference. 

appreciate your support with this,

many thanks

Hi @DaveClee, 

Thank you for the update and for sharing those details. I appreciate the effort you’ve put into troubleshooting this on your own, and I’m sorry to hear the issue is still persisting. 

To properly isolate the issue, I’d like to revisit a few of your previous troubleshooting steps with a slight modification:

• Create a new home: Create a new home structure to help clear app glitches. For detailed steps, please check out the article Organize your homes and devices in the Google Home app.
• Unlink Meross: Open the Google Home app, navigate to Works with Google, locate Meross, and select Unlink account.
• Re-link and test: Link Meross to the new home, recreate your automation, and test. 

Keep me posted on how it goes. 

Regards, 

Stephanie

Hi, I have spent a whole day deleting and resetting everything and it is finally working. It's just crazy that everything should have to be hard reset, when they're all matter devices!

[StephanieQ]

Hi @DaveClee, 

Thanks for following up on the case and sharing those details! I’m glad to hear that resetting your devices resolved the issue. I appreciate your cooperation and patience throughout this process. I understand your concern about resetting everything; however, devices sometimes need a refresh to ensure they work properly.
Please don't hesitate to keep me posted if you have any further questions.

Regards,
Stephanie

It is in fact now un-fixed, I've gone home and it's offline and not working again. 
how is it so hard to keep anything going on Google home right now?

Hi. 
I did create the automation In the app as standard, but no joy. 
in fact, the sensor is pretty much just always offline in the home app now, despite functioning as it should when viewed from its native app. 
If I wasn't so invested up until now, I'd be looking to jack it all in, it's infuriating!

same here. 

tried really everything(!) - days of efforts and my lifetime - I hate being an employee of all those greedy tech companies without getting paid for their lousy products. meross presence sensors stopped working in Google home and with homeassistant automation. both sensors, I have, did well for 2 weeks until about 2 weeks ago. 

HA logs are stating  triggers are sent correctly, yet no device receives them ...

Hi @hpichl, 

Thanks for posting in the community! I understand that you’re experiencing issues with your Meross Presence Sensors, which have stopped working in the Google Home app and with your automation. I appreciate the time and effort you’ve invested in troubleshooting.

Besides the steps you've already tried, if you haven’t yet, I suggest removing and recreating the automation using a different name. If the issue remains, I recommend contacting Meross directly, as the manufacturer, they have the necessary expertise to resolve concerns specific to their products. Here’s the Meross Contact Support page. 

Please feel free to keep me updated, and let me know if you have any further questions.

Best regards, 

Stephanie
