Compatibility

[jpuype]

I was wondering if the ebusd adapter is compatible with my existing Vaillant setup.
We have a 2008 ecoTec Boiler (with ebus), and a VR61 Mixer Module, a VRC430 Thermostat (controls the heaters) and a VR81 Remote (controls the underfloor heating).
I recently bought a Vaillant VR940F internet module, and while it is compatible with the Boiler it is not with the rest of the setup (I would need to replace the mixer module, Thermostat and its remote).

So I would like to double check before ordering ....

I own VRC470 and VR61 and it works without any issue. Also I add VRF470F into setup and it still works correctly.
Same like you I want to add VR9xx modul but investment was too high to change all modules to fit just internet connection, so my opinion was to use eBus and map it into HA. It was cheapest and works great for 3 years now.

@Koky05 how do you power the adapter? From the 24v in the EcoTec?
Also can one tap into the eBus anywhere (fi at the VR81 remote, which is in my office) or does one need to connect it on the Boiler itself?

@jpuype I use separate adapter for it, not directly from boiler.
