EN: MaxxFan controlled by Victron Cerbo GX - How it works (english)

[@Faustinojosem]

Thanks Marcus for sharing your knowledge with rest of people that are trying to setup nice integrations!!!

[@jeroenduppen]

Modules ordered 😉

[@roadbuck]

perfect!

me too 😀 arrived just now

Hallo. I have watched everyone of your videos and can't wait for more. keep up the good work,

[@roadbuck]

Thank you. The production of the tutorials is running at full speed ;-)

Hi Marcus, Really nice video you've done with both the Maxxair and Truma heater. I am curios to know how you are making the UI for this on the Cerbo? I know from your videoes you are using Node red for the integration, but are you using that for the UI as well or how are you doing that? I have a Nest thermostat in my van controlling the Eberspacher heater I have, and would like for it to be integrated into the Cerbo display as well

[@roadbuck]

Hi Andreas, the changes for the UI are coded. NodeRed is for the logic behind and the dataflow in the background. I'll explain that in one of the next videos. To integrate the Eberspächer could be a nice project for me as well. How or where can I find documentation about the Nest thermostat and the Eberspächer (which model)?

[@AndreasDybdahlOfficial]

@@roadbuck thanks for the info, I'm a software developer myself so that'll be no problem, but how and where do you code for the cerbo screen then? The eberspacher has a yellow wire for on control (12v) and that's it, so you would use a nest thermostat to control when to turn on based on ambient temp, and then connect a wire to the heating relay on the nest that'll connect 12V to the eberspacher when the relay is on. A video explaining that is here kzbin.info/www/bejne/lXbdo6Smm52Kna8si=Zoh0aXGW3dhrOiCf Basically all models of Webasto or Eberspacher to this day still use an on signal, they just turn on an off and needs a thermostat to control that logic

[@roadbuck]

Thank you for the details. I'll take a look at it!

[@matteburk]

@@roadbuck I m also interested in integrating a Webasto Airtop. As Andreas mention that the ebespräscher has one cable the Webasto works the same. I now use it with as shelly one for on and off and then a have a virtual thermostat in the shelly app and a tempsensor connected to shelly. Would be nice to have it on the Truma screen

[@roadbuck]

Well, then this should work in the same way. I have already thought about this and I think that it will not be very difficult to integrate this in conjunction with NodeRed, a temperature sensor (e.g. Ruuvi) and a relay.

Hello Marcus, very well explained and useful videos for those of us who want to unify everything with the Cerbo, but are you planning to make a video of the connection or do you have a website where I explain it, it is not very clear to me where to insert the raspberry pi and connect with Cerbo GX, thank you very much. I hope you understand what I'm asking. I used a translator.😉

[@roadbuck]

Hi, there will be a lot of videos soon. Actually I'm rewriting the complete code to offer a "Community Edition" for the MaxxFan and the Truma as well with an easy installer, and some minor changes to do by the user. You don't need both (Cerbo and Raspberry). Either Raspberry OR Cerbo GX... Website (roadbuck.de) and Instagram (roadbuck_de) is in progress
