Thank you very much for the very good documentation and information about OpenHab2.
A lot of things were very helpful, even though there are still some questions unanswered. That’s why I hope to get some questions on it in this round.
A year ago I bought a house in which a building automation was already installed. I found the following hardware here.
PEHA PHC with the following hardware:
Control module 940 STM (Software v1.xxx)
3 x input module 940/24
3 x output module 940/10
1 x output module 4A 940/4
2 x Dimming module 943/2
Since PHC PEGA was discontinued by Honeywell, I now have to decide what to do. I would like to take over the installation of PHC PEGA because I have the high cost and effort to renew the wired installation all over the place and would rather only modernize parts instead.
I would like to automate the following in the coming year:
- Sockets (if possible take over already installed PEHA PHC)
- Lighting control (if possible take over already installed PEHA PHC)
- Garden lighting (no hardware available yet)
- Dimmer for LED lamps (no hardware available yet)
- Heating automation (ground floor servomotors on wall radiator / upper floor underfloor heating)
The heating is completely modernized during the year. Probably the decision will be made on a heat/air or heat/heat pump.
- Room climate monitoring (no hardware available yet)
- Change from Alexa to Snips.ai
- Integration of the Logitech Harmony
Now to my questions.
1 According to the OpenHab documentation, PHC modules can also be connected to OpenHab without the control unit (binding). Do I understand that correctly? So is no 940STM module ore needed in upgrade anymore? https://www.openhab.org/addons/bindings/phc/
2 Unfortunately PEHA does not offer modules for LED dimmers. Can I integrate other modules here via OpenHab, which then take over the dimming control?
3 I am already using a Synology NAS DS918+. When using OpenHAB and Snips.ai, would you integrate everything on Synology or would you rather use one or two separate Rasperry Pi? Probably using separate Rasperry Pi is easier in case of a problem.
4 I probably won’t be able to do the installation on my own. Although OpenHab is really clearly laid out, I’d also like to call in an expert. Our electrician refuses anything that is not KNX. Therefore the question if you know a forum where I can ask or if you know someone who can support you with the setup remotely or on site (NRW) against payment.
I am happy about any comment or info. If I forgot important points, please let me know. I’m in no hurry. I would like to tackle the project in the course of the coming year.
Many thanks in advance
