There is a thread here discussing the issues of the M1-C-bus interface and lack of response from Ness in regards to fixing it. The question was asked if there was an alternative panel that has C-Bus interaction that would be similar - no real answer was given. Coincidentally, an old thread popped up the that talked about a C-bus to KNX gateway for the Comfort by Cytech (not Schneider Citect) which reminded me of this product and sent me searching through their site again. This appears to be exactly what I am looking for in a replacement for the M1 but I would like to know if anyone here has any real experience with the system and can give some feedback. it appears to be going strong with lots of options available, whereas Elk who are not struggling don't seem to be developing anywhere near as much as Cytech are.
