Hello Everyone and thanks in advance for answering my questions.
Quick overview:
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.
Questions:
Motorized Curtains:
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?
Scene controllers:
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?
HVAC Integration:
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.?
Light dimming:
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?
Sensors:
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?
TV integration:
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.
