Hub recommendation for Velux io + somfy sunea io?

Hi,

I would like to hear your recommendations for my existing and growing setup.

Status Quo Overall
I am running openhab (currently 3.2.0 on ubuntu) for several years now, do integrate stuff on my own with ESP8266 + soldering, have a bunch of homematic sensors and actors, mqtt, http-binding for water softener by myself etc. One of my main priorities is: as few communication to and from outside of my home as possible. Thus I have a netatmo rain gauge, but it only provides data, no rules depend on them.

Status Quo Shutters
I have some shutters for my velux roof windows, e.g. GPU PK08, they are solar powered with Velux Integra KLI310 or the older KUX100 (both with this homecontrol io label). As velux’ connected solution were a bit expensive for this sole purpose, I opened the controller cases, soldered some wires to it and connected them to a Pi, quite similar to this blog post, but with mqtt and connection to openhab. Since the windows have sensors for closing position, it works but is not perfect.

What to achieve
Today I got an awning with an integrated somfy suneo motor and a linked eolis wirefree wind sensor. Now, as I understood, both the velux stuff I have and the new somfy components are “homecontrol io”-compatible and thus I can control them with one unit - and this unit can provide a reliable connection to openhab.

What I already know
There a several solution for my question, e.g. mentioned in this topic, but at least 6 years old. There might be another solution, but does it work for openhab 3.x?

What I still want to know
What are your recommendations and/or experience? Currently, Velux KLF200 seems to be the cheapest solution (below 150€), but does it really work well with somfy and is is capable of at least 5 actors (4x velux, 1x somfy) with a minimum of 2 somfy to come? How reliable is the connection to openhab? Should I remain with my soldering+pi-workaround for the velux stuff and find something for somfy only (but TaHoma seems to be expensive for just 1-3 motors and the wind sensor…)?

Thank you for your recommendations! If there are any questions about the setup, please ask.

I could have missed something in your post or in your prerequisites, but why didn’t you mention the Velux binding as a solution ?
It uses the KLF200 as a bridge, is stable, can communicate with some other IO Homecontrol non velux devices, and works quite well.

You can also find support in the forum discussion.

I did not mention it because my main question is about the hardware, binding is coming afterwards. I am aware of the Velux binding and also Somfy TaHoma, but I am not really sure if there are compatible hubs which use the binding and the best hardware for my needs.

I use the KLF200. The “5 actors” you are referencing is the ability to connect 5 hardwired switches, with which you can control actuators like windows, sunscreens, curtains, etc. However, using the API (or the OH binding), a lot more actuators can be controlled via the io protocol individually.

I have 6 Velux actuators: a skylight, a roof window, curtains for both windows and sunscreens for both.
I also have two Somfy acuators: A patio awning and a zipscreen.

All 8 actuators are functioning excellent via KLF200. Following the forum topic mentioned by Gwendal, the binding for openhab is well maintained and missing functionality (slat position of certain Somfy actuators) has recently been added and is under testing.

Adding to your comment

One of my main priorities is: as few communication to and from outside of my home as possible

The KLF200 is purely local, whereas the Somfy hardware is via the Somfy cloud, which creates its issues when Somfy servers are down or they change security causing authentication issues, etc.

Regarding your eolis wind sensor, I have been looking into that one a few years ago. From what I understand is that you pair the actuators to it and the wind sensor will steer the actuators up (or down) and block the actuators for a certain amount of time that you can set on the eolis itself via a potentiometer. So I don’t expect the eolis to communicate with the KLF200 or TaHoma.

Thanks for your input, I’ve ordered the KLF200 and will update about my experience when in use.

The KLF200 supports 200 actuators. Including Somfy devices. There is an upgrade in the pipeline to support vane/slats on venetian style shutters too.

Pretty good.
