New Venta Original Connect / 500 series

[johan-de-jong]

Venta has new 'Connect' (Wi-Fi) models for their original series. E.g: https://www.venta-air.com/en_de/AH555-Original-Connect-Air-Humidifier/7055500

The 500 series does not have a configurable color LED. It has 3 fan speeds (+ off) instead of 4. The JSON API seems to be similar.

Would you be interested to update your plugin?

Apologies for the delayed response. I'm interested to update it, just not sure when I'll have the time. Soon, hopefully!

Thanks for providing the API responses, they will definitely be helpful.

That sounds great! I will gladly test the update when the time comes. If you like I can also post the API responses for the Venta AirSense Pro.

For now I have configured rest_command on/off and fanspeed entries, and some REST sensors. I converted the ServiceT to time remaining (Venta needs service) with:

value_template: "{{ ( (value_json.Info.ServiceMax - value_json.Info.ServiceT) * 10/60/24 ) | round(1) }}"

I found that the ServiceT is expressed in 10 minute blocks.

I also configured a 'Generic hygrostat' to turn on/off the Venta as needed to maintain the desired humidity.

I have yet to figure out a way for the hygrostat to automatically change the fan speed to a sensible setting.

The device always accepts: '"SleepMode": 1,' to dim the display. When using the app, sleepmode dims the display and sets the fan speed to '1'. With the API a dimmed display and fan speed '2' or '3' is also possible.
