My house was built in 2006.
All stuff regarding heating confort are controlled by a proprietary DDC that was supplied by a local Belgian company that supplied the solar boiler system. I integrate also wood boiler, multi zone underfloor heating and cooling, ventilation, blinds …
The system got a big update in 2010 and 2016 but fullfil my main needs.
One month, I begin to have problem with some pt1000 UI module and learn that the Belgian company stopped developing and supporting the product.
So I am searching for a new solution for my BMS.
After one month inverstigation, I came to the conclusion that OpenHab will be part of the solution for his ability to integrate also my other light control domotics.
But regarding heating control, I hesitate between T3000 and other Sedona based controller.
I also want to do the migration step by step when my existing system is still working.
The only “open” way to communicate with my existing system is RS232 with proprietary ascii protocol allowing me to read/write IO and VAR.
I plan to use my rapsberry pi 4 with node red to run a gateway between my proprietary system and new Pt1000 reading connected on a T3000 or expansion PT1000 card.
Do you think it is possible ?
When the new control program will be ready, I can migrate to T3000 function by function.
My existing platform was programmed using compute, logic, sequential and heating function blocks .
I have the source code of all function bloc and I want to reproduce,at the beginning the logic that was validated and tuned for the last 10 years in my house.
I saw that sub program can be defined to simplify programming but the T3000 software manual i found on Temcowebsite (2017 édition) show a table with maximum 16 programs.
Is this limit still active?
Are there an easy way to add user function bloc library ?
I did not find any reference to Temco on OpenHab Community forum but T3000 should be seen as bacnet controller, if somebody already experiment it I would be happy to discuss the possibilities .
Thanks for feedback
