Hi Community,
I’m about to move in a new house which I’d like to upgrade to be “Smart”. After doing a lot of research please allow me to share my thoughts with you to be proven for plausibility:
Change all heating thermostats to HomeMatic IP, including windows contacts
get a Raspi with Homematic module, install Raspberrymatic for using the Raspi as CCU
get 2nd Raspi (as obviously RPMatic doesn’t allow any further installation (own image)), plugin Conbee II USB for Zigbee
install Home Assistant and deCONZ on Raspi2
upgrade light switches with zigbee inline switch, to be able to control light via both switch and app
replace bulbs with zigbee bulbs, partly RGB, partly white
connect Home Assistant to IFTTT to trigger geofencing actions
use window contacts to both heating and alarm functions
install smoke alarm, use siren also for intrusion alarm
use aqara environmental sensors to detect temperatures and humidity to control heating accordingly
install IKEA Tradfri rollos to be controlled also via Home Assistant
Does it sound like a good plan or am I missing something here? As far as my research goes I shouldn’t need the original Homematic CCU or AP then and also no Hue Bridge, as Homematic will be controlled by the first Raspi and Hue by the second, right?
Hello curzon and welcome to the forum. That sounds good. With the Conbee Stick you can control the listed devices a HUE Hub and TRADFRI Hub is not necessary for the lamps. With the roller blind I’m not sure if you can control the synonymous with Conbee Stick (have no!) I would also like to buy the thermostats from Homematic IP and have read somewhere in another forum that the Raspberrymatic ist not so stable as the original Homematic IP Bridge !?!
Unfortunately, I can not say what the integration of Rasberrymatic in HA looks like.
I have the deConz module on the PI on the HA is also installed with a 2.5 A power supply and he runs without problems …
I have been using RaspberryMatic for over a year now, and I find it rock solid. I did have a CCU2 but it was very slow and you could not add any extra software such as NodeRed. The Homematic thermostats look a little cheap and the display is tiny, but they work fine. The TRVs are great.
Homematic integration with HA works well, but rebooting the CCU requires a HA reboot to reconnect. However, the CCU reliability means that this is rarely a problem.
I would advise you to use the wired version of Homematic as much as possible, if you have the opportunity to run cables during your house upgrade.
I have had less success with deCONZ as I fnd the range is very limited and devices disappear occasionally.
Personally, I avoid smart bulbs, I prefer to use smart switches & dimmers.
Have fun!
Thanks very much for that feedback. We should get the contract for the house this week - after that I’ll start to order the components and start to set up the system - to be able to install it quickly once we’re moving in.
Hey all,
just a short update: Decided against HomeMatic, because I got a great offer for Zigbee thermostats, which I can use without a separate gateway. So at the moment I already set up the Raspi, Hass, deConz with ConBee II and a Ledvance Smart Switch to test everything. In parallel I ordered Aqara window and temperature sensors, which will be used to control the thermostats. So far no big obstacles yet - I’ll keep you posted!
Hi thermostat,
actually I installed the system today and after some issues during device discovery it finally worked. The thermostats even showed up automatically in Alexa.
Controlling them works.
I also got not problem at all controlling the Eurotronic Zigbee thermostat.
What was really a pain was to control them with an external temperature sensor (the onboard temperature sensor was unuseable in my case, even if I configure an offset).
