Hallo.
Thank you for the app.
I’m a proud owner if the NRG CVE module since the day before yesterday (=friday) and are testing it together with your app. (Sometimes nothing happens at all when I issue an order through the app 
).
But my biggest (feature) requests are to add just a When .. “Ventilatiemodus verandert” (without to have to specify to which mode.
Hi,
The state of my slider and the presets are not changing when I change the state on the nrg web app or home assistant. If I change the state on the Homey app the fan reacts as expected. I do see the fan speed change in the overview page.
There is some delay between Homey and NRG, after 1 a 5 sec still not updated? Send me a DM
Maybe this is a feature request, but do you think you can include energy measuring? Based on fan speed make a guesstimate?
This morning I created a new test version 1.1.0 with better support for WTW units. Can somebody with a WTW Unit test this version?
Have the same “problem” , slider / state does not update and changes back to the previous setting. The fan speed does change.
I’m running into the following issue:
Through the app, I have added NRG CVE module. Via the Matter Bridge, they become available in Apple HomeKit.
In Apple HomeKit they are displayed, but with the message “Not Supported”. I understand this may be caused by the app using custom capabilities instead of the standard Matter/HomeKit capabilities.
Could this be adjusted?
Is this something that could be resolved in a future update?
What Integration are you using? HomeKitty ?
I have the Matter Bridge integration
Thanks for the information. I’m not really familiar with Matter myself either.
In addition to the Matter app, I also installed the NRG.Watch app (NRG.Watch | Homey). Through this app, it does show up as a sort of switch. The ventilation does turn on and off.
Additionally, I also installed the HomeKit Device Bridge app
(HomeKit Device Bridge | Homey). In my opinion, this one is displayed correctly.
I don’t know if this info is of any use to you?
After updating the Itho module to version 3.2.0-beta1, the switches/sliders do not stay in a stable position. They move continuously up and down. What can I do about this?
Can you test Version 1.1.2 — Add beter support for WTW units ?
The test version
I I have tested with the new version. The problem is not yet solved.
Test version 1.2.0 is released see Itho Daalderop | Homey
Please update first to 3.2.0 firmware
I have tested with the new version. The problem is not yet solved.
Can you send me a DM?
Matter App does not support fan devices yet, you can ask Homey to create support for fans and other devices. I have created a fork and add support for it:
Only you must install it in dev mode.
This problem is fixed in the latest test version, thanks for your help.
Hi Stèphan, thanks for the app!
Quick question about the WTW driver. On my HRU ECO 350 (add-on firmware 3.2.0, app 1.2.3, Homey Pro 2023) every command returns:
API failure: remote index number higher than configured number of remotes
The WTW device settings only show “RF Apparaat Type” and “RF Apparaat Index” — no virtual remote setting like the CVE driver has. My RF devices list has an empty slot at index 0, which would explain the error if WTW sends via RF only.
Meanwhile a virtual remote on index 0 (RFT CVE) is joined and works perfectly from the add-on web interface: High sets Actual mode to 3 and the fan responds. The CVE driver in Homey also sends commands fine on this HRU, but shows almost no sensor data.
Would it be possible to add virtual remote support (type + index) to the WTW driver? The HRU 350 has a working I2C connection, so virtual remotes are supported on it — only the 250/300/400 are RF-only.
Happy to test a beta if useful.
