Finally a full control solution for the ITHO

NEW version 1-2021
I have installed this ITHO Add-on for my ITHO home ventilator. Now able to fully control the ITHO vent

This fits nicely in to you existing ITHO and you don't need to solder anything.
It has an extra 868mhz transmitter and existing ITHO remotes are learned in by this add-on
This way you are in full control and can even see (or get an MQTT message) when somebody pushes the remote.
So controlling it via your home system and the remotes is fully possible now, also always the exact status.
Check the website where you can order the PCB for more details.

Tested with Itho Daalderop CVEs from late 2013 and 2019 (PCB no. 545-5103, 545-5103, 545-5104, 05-00492, 210-0177, 05-00492, 210-0177), also confirmed working on other models. Most important, look for the 2x4 pin interface on your main itho PCB (encircled in red on the fifth image). If this interface is present it is likely the module will work.
