Hello Everyone and thanks in advance for answering my questions.
I am building my home, and all the walls are currently open, and I have the chance to wire everything correctly and choose the correct devices.
After a visit from couple of smart-home companies and the high-cost quotations I received I decided - since I am already an electrical engineer, and a programmer to set on building the system myself.
I am Canadian, but the region I am building the home in works on European standards (240V).
For standard light / outlet control I built my own Arduino / Nodemcu circuit and integrated it with Openhab using MQTT, and even added a quick DHT11 temperature sensor, and created rules on Openhab to run on and off devices based on temp.
So far, every time I google, I end up with Somfy, and Openhab binding with Somfy. My biggest issue is that it looks like I need to buy their hub / bridge and the binding connect online to their services. I’d rather not have any control in my house depend on the internet as the connection here is unstable, and also I would like to have my equipment work directly with Openhab without middle hubs.
Q: Can the community help me locate a motorized curtain system that can work natively with Openhab?
For open spaces (living room, kitchen, reception, etc…) I am planning on using any cheap mounted android tablet and have HAB-PANEL running on it to control lights/ curtains/ scenes. For bedrooms, I would like a button-based solution to avoid the light from the tablet to bother whoever is sleeping scene controller solution with 6 to 8 buttons that works natively with Openhab. Without having to go through another hub like Insteon.
I found this: https://www.amazon.com/ZRC-90US-BW8510US-Remotec-Cert-ZC10-15100007/dp/B016YTTIVW/ but unfortunately it is US Z-wave standard not Europe. I am also hoping to find something that doesn’t require battery replacement.
I can also integrate the scene controller by merging it with the nodemcu system, but in this case I need the keypad with pushbuttons only, and I am not sure where I can find something like this.
Q: Can the community help me find a 6 to 8 buttons scene / curtain keypad controller that works natively with Openhab or a keypad only and I will build the circuit on top of it?
I have contracted HAVAC systems from Trane. For regular split AC systems that supports cooling/heating there is an interface board that connects to the AC that will allow any regular 24V thermostat to hook up into it.
Unfortunately, I also have another section in the house that has concealed AC system (Trane MCD) that works with high voltage (line voltage) thermostat. For that one specifically I am completely stuck.
Q: Can the community help me find an Openhab compatible thermostat, one for the regular AC system, and one for the high voltage one.?
There is an open area in the house that will consist of about 60 LED light, each 10 LED light will be turned on and off and dimmed together. So, 6 zones x 10 LED lights each.
Due to the sheer number of lights, solutions like Philips hue is out of the window as it will cost an arm and a leg, plus the fact that it uses even a third wireless technology (ZigBee) and requires another hub.
Other cheaper alternatives have their own app and I have no clue if they will integrate with Openhab they’re just listed as Alexa, Google assistant compatible.
Another way of doing this is installing a smart dimming switch. But that means I need 6 of them, and my plan was to use a tablet to make scenes and control the light.
Q: Is there an in-line smart LED dimmer compatible with Openhab natively, that optionally and hopefully can also provide RGB (color) control? and What lights can go with it?
I need 3 sets of sensors. Quad-sensor (Motion, light(lux), Temperature, Humidity) for all areas, a smoke, flame, co2 in the kitchen and in front of the fireplace, and window/ door contact sensors on all windows, and some doors.
I am going back and forth between getting sensor modules and hooking it up to the nodemcu myself, and between having a proven, nicely packaged ready sensors to install. And I seem to favor the last option.
Q: Do I have to go Z-wave route for sensors? What other options do I have? Which Z-wave sensors work with Openhab? Has anyone tried a manufacturer with nicely packaged sensors that can be hooked up to Arduino/Nodemcu?
Q: I see LG/Samsung bindings with Openhab, but they seem old to me, and have issues with latest TV sets. Am I wrong and they work fine? or should I prepare for IR sensors for TV control?
Sorry for the long post and looking forward to your assistance.
