Hi, does any one know how to control this RFZ device [https://www.zehnder.nl/producten-en-systemen/comfortabele-ventilatie/zehnder-rfz](https://www.zehnder.nl/producten-en-systemen/comfortabele-ventilatie/zehnder-rfz) ? I like to control my ventilation in the when CO2 is rising or when humidity is too high. ---

Since Homey has problems learning 433 Mhz signals, I would recommend you a Broadlink RF pro. He can read the signals and pass them on to Homey. > **[Broadlink RM Pro+ WLAN Smart Home Hub: Amazon.de: Elektronik](https://www.amazon.de/Broadlink-Automatisierung-Fernbedienung-Kompatibel-Smartphones/dp/B07CNP9MGS/ref=asc_df_B07CNP9MGS/?tag=googshopde-21&linkCode=df0&hvadid=380203681351&hvpos=1o1&hvnetw=g&hvrand=8053941934369600398&hvpone&hvptwo&hvqmt&hvdev=t&hvdvcmdl&hvlocint&hvlocphy=9041956&hvtargid=pla-567739115199&psc=1&th=1&psc=1&tag&ref&adgrpid=79218872564&hvpone&hvptwo&hvadid=380203681351&hvpos=1o1&hvnetw=g&hvrand=8053941934369600398&hvqmt&hvdev=t&hvdvcmdl&hvlocint&hvlocphy=9041956&hvtargid=pla-567739115199)** > > Broadlink RM Pro+ WLAN Smart Home Hub, Universal-Fernbedienung mit automatisiertem Lernen, IR und RF in einem Gerät - Schwarz bei Amazon.

Maybe just handy to settle down exactly which ventilation system you have. If you have a zenhder comfort system then you can do this with the 0-10 volt contact which is on the ventilation system. Then you could build in a qubinio 0-10v dimmer and operate the ventilation system with it ---

I have a inventum ecolotion 50 combi heat pump/ventilation. Do you think it is possible to control both rf (71) and 10V (66)? ![Schermafbeelding 2019-12-09 om 10.29.26](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/7/278ffa574008ffbc694cdc145558ac545b55345e.png) ---

you can connect a qubinio 0-10v module to the circled contacts. I do want to advise you to take the current RF modules / receivers out of it, because there is a chance that they will break if you leave it in place and connect an external 0-10V module, I know from my own experience. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/f/bff783bc26eb976de70d96177d31977411626f72.jpeg) ---

If you have any questions about connecting the ventilation system, you must let us know. Thank you and good to hear that you like my site. I try to make it a nice site. Did you already see the new flow page? There are some flows that you can use for the ventilation system. ---

hi guys. Any update on how it is working with inventum ecolotion (is it nearly equal to " de warmtewinner" from Eneco/ Inventum (spaarpomp) [https://www.inventum.com/producten/inventum-spaarpomp/](https://www.inventum.com/producten/inventum-spaarpomp/) ? ) in combi with the qubinio 0-10v dimmer? Or anyone used the idea from the undertaker (broadlink RM Pro+)? [https://www.inventum.com/wp-content/uploads/2020/01/Installatiehandleiding\_Spaarpomp.pdf](https://www.inventum.com/wp-content/uploads/2020/01/Installatiehandleiding_Spaarpomp.pdf) page 30 is the electrical scheme. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/d/dd5a4ee2773a781cb9dfd00ff93237d27c368399.png) ---

Would be also interested as I have the Spaarpomp ---

+1 here. I don’t want to intervent with the electric circuit (i’m renting the house, it’s not mine). The Zehnder does receive RF signals. If Homey can transmit them, i hope someone can write an app for it. My system: Zehnder Comfofan S with RFZ remote. Kind regards, Heronimus ---

I’m also curious if anyone has created an app or has another solution to handle the Zehnder ventilatiebox. My RFZ is out of order, so I like to send the signals with Homey instead of buying a new Zehnder RFZ. Anyone an idea? ---
