Starting with HomeMatic

Beitrag von BeyondRico » 24.11.2020, 11:55

I want to get started with HomeMatic and want to integrate it into Homeassistant but still have some questions.
I ordered the following stuff from Homematic:

5x HMIP VD24N Actuators 24 V
1x HMIP FAL24-C6 HomeMatic IP 6-way underfloor heating actuator, 24 V
1x HMIP FAL24-TR HomeMatic IP transformer for underfloor heating actuators — 24 V
2x HMIP ETRV-B Radiator thermostat - basic
1x Homematic IP Access Point (basically got it for free)
1x Homematic CCU3
3x HMIP STHD Homematic IP Temperature-Humidity Sensor Disp.
There are 3 zones in the house that use floor heating, because of that I ordered 3 temperature sensors and 5 actuators (one zone has multiple heating groups). The radiator thermostats are for upstairs and will be controlled separately. However my first question here is am I missing something to make this work and is the Homematic IP access point unnecessary in this system (as mentioned basically got it for free). Second question is that on the floor heating unit there are 5 groups (where the actuators will be placed) but there is also an other valve to control the temperature, does this valve also need a smart radiator thermostat? See the picture for reference:

I see no picture

I would change the HMIP-STHD with HMIP-WTH-2 to control the room temperature

What will be your central gateway CCU3 or Access Point ?

If CCU3 is the main gateway than the Access Point can be used in the network as range extention (Advanced Routing)
If you choose that the Access Point as the main gateway - than you need no CCU3.

Something went wrong with the image, here it is : https://imgur.com/a/MkO3nFp
The central gateway will be CCU3 because I need it to connect to Home assistant. From there I will control the temperature, that's why I chose the HMIP-STHD and not the HMIP-WTH-2. I will use the access point as range extender then. I hope you can answer my question now that the picture is available.

Sorry I checked your picture but not sure what you mean/not clear to me - maybe you can explain it again?

Home Assistant has 2 solutions:
For CCU3 (no Cloud)
https://www.home-assistant.io/integrations/homematic/

For Access Point (Cloud Solution):
https://www.home-assistant.io/integrati ... cip_cloud/

Home Assistant is a good solution but also the Alternative e.g. iOBroker is good - check here:

Check also the links and Topics here:
viewtopic.php?f=49&t=45485

As a direct App to control the Homematic gateway I recommend to test the Smartha App

I will stick with Home Assistant because I am already using it for almost 3 years and like it very much. About the picture on the left side you see 5 valves that control each group(on the red hoses), on each one there will be placed an actuator. However on the pipe that goes directly into the floor heating unit on top there is an other valve that has the different temperatures marked on it ( 20, 30, 40 degrees etc.), does this valve also need some kind of smart thermostat or should i just leave it open at max because the system will control the temperature?

For that valve that you mention I would NOT make it smart. I also have something like it in my setup but that valve you want to keep it constant at a certain temperature ( you don't want to change it for years) and that controls how hot the water will go into the floor heating. Since the floor heating is quite sensitive on temperature ( as far as I know max should be 40 degrees ) cause high temperature can have negative impact on the floor, this is why I would keep that one as it is and that will also act as a fail safe. But this is just my thinking ;) of course you are free to do what you please ;)

That's what I thought, thank you for confirming this. But how it basically is working then (if i understand it correctly) the sensors sees the temperature in each zone. Depending on which room needs more heating the actuator of that zone opens, and sends a signal to the central heating system to heat the water(I also orderded the switch actuator)?

Well, basically it works like this. The WTH thermostat in the room sees that it needs heating, it sends command to FAL actor of that room and the valve opens for that room. I don't see a device that can control the boiler in your list. There is a device called MIOB box and another smaller version of it that can trigger the boiler and boiler pump. You can read about them and that device will connect to the FAL device and when there is a need for heat it will turn on a switch actor.

I am sorry I mean this device: https://www.homematic-ip.com/en/product ... nnels.html
this one controls the boiler am I right? I did not mention it in my list but I ordered it as well

Yes. This is the other device that I talk about. It's a smaller version of the MIOB box and it's doing the same thing. But you will have to make sure to configure it properly. It's not that straight forward. I also have this and if you pla to use CCU make sure not to use switch toggle but use switch ON for a certain time. Otherwise your boiler will turn ON and OFF all the time due to cycle in use by eq3. You will understand more when you will configure it.
