I just ordered a second rf controller to build this. Just to be sure: you only use the power supply that is connected to the wemos? So the battery in the rf controller is not needed right?
I think I will use esphome to flash the wemos. No coding required at all 
Correct, I use a NodeMCU, basically the same setup. ESPHome would indeed simplify this method even more
I also have a Buva Qstream (hygro version) which has inputs but not the 0-10V connection. Does anyone have an idea how to connect this to HomeAssistant. https://www.buva.nl/uploads/knowledge/q-stream-installatiehandleiding-2017-06.pdf
Hi everyone!
This is a slightly older Thread, but still relevant.
I have a Vaillant Recovair system and can control it via the Quobino. The Hardware part works well and the slider in the app (HA) now controls the ventilation.
Now the tricky partā¦
I want to have this automated based on sensor readings. My first attempt is to read humidity in the bedroom and have the ventilation automatically adjust within a certain range if certain thresholds are reached. Sadly I have no clue how to do this.
I managed to set up an automation that should increase the ābrightnessā of the Dimmer when the humidity exceeds 50% but I have no control over how much it increases or anything like that.
Also, so far it seems like the automation doesnāt trigger even if the value is reachedā¦
Any pointers?
Thanks!
Hi I recently started with ha and I found this. Did you do jou have a working system. I ordered everything and made the connection to the remote. I programed the wemos with Arduino. But no succes. I can see the board in my wifi netwerk but if I type the IP adres the I get no response. You say in your reply that you Program the wemos thru esphome is there any documentation how to do that or can you help me?
Hey folks, i know this is an old thread, but if anyone succeed, Iād love to understand how, because i am slightly stuck. To demonstrate i did my home work 
:
i went for the ESP8266 (Wemos D1 mini) route with PWM, based on this thread:
Aansturing Mechanische ventiatie via KNX RF - Duurzame energie en installaties - GoT
However, in contrast to @Antoine_Evertze, I have an even older version of the BUVA Q Stream, which has the 0-10v control input and 12v out (0.3amp):
However, while my Wemos is working fine. Its powered via USB and i have this PWM DC converter between the BUVA 0-10v and PWM ping on Wemos: PWM naar spanningsomzettermodule 0%-100% tot 0-10V voor PLC MCU Digitaal naar analoog signaal PWM verstelbare converter voedingsmodule - AliExpress 502
The PWM Converter is active, but the Wemos is not registering any RPM:

My ESPHome yaml: [esphome/ventilation.yaml at main Ā· henkkie055/esphome]](esphome/ventilation.yaml at a9dd5d9efb91da9f0194710466c698888f6424ce Ā· l1vb2/esphome Ā· GitHub)
Any suggestions?
