I’m excited to share a project I’ve been working on: a Homey app designed to integrate Itho Daalderop ventilation systems with the NRG.Watch Wi-Fi module. I originally built this app for my own setup, but I’ve decided to share it with the community in case it helps others too. Why did I build this…

Cool! What is different from the nrg app?

Nice! Installing as we speak. It shows temp & humid correctly, but the commands from the Homey device aren’t received yet by the nrg unit. Pro 2019. Just let me know what I can do to help. Note: I have a virtual MQTT device running for nrg as well.

The other app has fewer sensors and does not support devices with a CO₂ sensor. It also doesn’t work on 2019 models. Initially, I tried fixing the current app, but it turned out to be much more work than rebuilding it from scratch in plain JavaScript.

Thank you for your help. The issue was caused by the ‘Normalize keys’ option being enabled. In version 1.0.4, I’ve implemented a fallback mechanism that automatically normalizes keys when the non-normalized ones are not found.

No problem, Stèphan. And thank you! Some possible improvement ideas: 1..When adding the device, login fields are presented. But they’re not mandatory as I discovered by leaving them empty. But it got me confused a bit. Maybe it’s more clear when you add “Only if API needs authentication” or a t…

Version 1.0.5 has descriptions and tooltips in pairing mode and settings mode.

How can I add the vorituel remote on on my itho ?

You must order first a NRG.Watch module ( https://www.nrgwatch.nl/shop/ ) and install this module in your ventilation.

Hi, Thanks for the app, I was using a VD in combination with HTTP request but this is much more nice. I’m having the built-in CO2 sensor so I have to use the virtual remote. If I select the Automatic mode the unit is not picking it up and continues in the previous mode (the mode selector is also j…

The nrg.watch app is not able to add the nrg add-on to Homey for some users, me included.
The support request to (hopefully) solve it is now 11 months old.
