Hi everyone!
I have created a new Homey Pro app for Grohe Sense and Grohe Sense Guard, and a test version is now available for public testing.
Overview:
- Control the Water Valve: Open, close, and toggle the main water supply (Sense Guard).
- Monitor Telemetry: Read water pressure, flow rate, consumption, temperature, and humidity.
- Alarms & Security: Receive instant notifications and trigger flows for water leaks, micro-leakages, and frost warnings.
- Easy Setup: Log in directly with your Grohe account credentials during pairing.
Install test version: Grohe Sense - test
I would love to get your feedback before submitting the app for official certification by Athom. Please share your thoughts, test results, or bug reports here in this thread.
I litterally just prompted Claude to write an app for Grohe Sense Guard, when I searched the forum and found your app.
So far your app works and looks great. All sensors/data and the on/off button works.
A few suggestions:
In the next version perhaps you can add a setting or button to clear alarms? (i get an alarm every few days due to a leaky toilet, and it would be nice to be able to clear the alarm in the homey app as well).
Also your links to sourcefiles and issues/support on the test download page are not working. You might want to update before you submit to publish with Athom.
Anyways, you just “ruined” my evening with Claude
I will look for a different project.
Good work.
Thanks for the feedback @Morten_Bech! Sorry if I robbed you of the joy of vibe-coding it yourself 
I’ll look into how to make it possible to clear an alarm. It will likely need to be a selectable status setting you can set. I’ll also make sure to publish the code on GitHub and update the information.
I will post here as soon as I have something ready for testing.
New test version (v1.1.1) of the Grohe Sense app is now uploaded and available for testing!
What’s New in v1.1.1:
-
Silence Alarms Button: Added a dedicated “Silence Alarms” button directly on the device control page.
-
Unified Alarm Control: Instead of cluttering the UI with individual buttons for every alarm type (water leak, micro leak, frost), I opted for a clean, unified button that mutes and resets all active alarms at once while keeping all three alarm statuses neatly visible on the sensor overview.
Flow Action Card: You can also silence alarms automatically via Flows using the new action card “Silence / Reset alarms”.
It’s tricky to simulate alarms at home so I haven’t had the opportunity to physically test every alarm trigger. Feedback and test reports from anyone experiencing or testing alarms are very much appreciated!
You can try out the test version here: https://homey.app/a/net.lindbom.grohe/test/
Had a micro leak alert this morning. It could be silenced by pushing the new silence button. So seams to work as it should.
Good to hear! Not about the leak itself, of course, but that the alarm silence button did its job.
I have just submitted version 1.1.2 for review by Athom so it will soon be live in the App Store.
In this update, I also decided to remove the Total Consumption meter, as the GROHE API doesn’t provide a reliable lifetime odometer and it wasn’t possible to calculate it accurately. The Daily Water Consumption is preserved and works reliably as intended.
The app is now published in Homey App store!
