I looked at this page at least a dozen times, and have overseen this information 
Thanks, this is enough to order this little bastard and get my somfy blinds into HA.
The last missing piece from a time I had no clue how locked in somfy is and how much I hate this mindset
Thanks, I will update the thread as soon as the box arrives 
I got my somfy connectivity kit today and it was successfully detected by the homekit and overkiz integration
Did not had much time for testing now, but the box gets reported as… using overkiz
Whereas homekit reports the following
So if you need someone for further information, to get the integration working “correctly” with the box - let me know
Thank you for this post. I’m following the topic with interest. I would like to control 8 Tahoma roller shutters, 3 Velux roller shutters and 3 Velux electric window openers with HA. So a total of 14 io-homecontrol devices. The Somfy Connectivity Kit for currently €69 seems to be the cheapest solution at the moment.
I am particularly interested in the following questions:
Can the Velux devices also be controlled?
Is the Velux rain sensor on the roof window even displayed?
Does it all work without an internet connection?
I do have 16 devices, some awnings, some blinds (shutters however they are called correctly in english) anyhow, they all work, I do not know which motors are used for the awnings and blinds on the balcony, but as long as they report via IO this should be fine.
I also used VELUX controlls with my somfy motors, all not an issue as long as they are IO-homecontrol compatible. I think this is the only good thing about IO-homecontrol, companies get forced by somfy to follow the standard 
instead of using the controll.About the Internet, you need at least a working WIFI and IP network otherwise it wont work. So if your router is the WIFI entry point and the Internet provider, if this goes down, you won’t be able to control anything because devices most properly cannot “switch” data or lose their IP addresses.
With a Tahoma Switch, you could at least use the physical buttons with the “scene” option, or just a spare remote in case of the connectivity kit
See Fiche comparative TAHOMA SWITCH vs KIT CONNECTIVITE_A4_1221.indd (somfy.com) for a comparision between the Somfy TaHoma switch and the Somfy Connectivity Kit.
And it mentions something every interesting next to the cloud access. By the way, I am not sure if sensors are supported, but my French isn’t the best. You should be able to read this table better.
Mine is non-existing 
But at least I understand that security, thermostats and others seem not to be supported
The part with local api and cloud - I do not understand 
Mine is cloud controlled, so I am not sure if I read this table right.
And placing homekit into the voice assistant section - hmm - very very strange comparison sheet.
If you connect HA via Homekit - YES.
You mean connect via HomeKit protocol or via some Apple service?
My goal is control my blinds without internet. I’m OK with limitations you mentioned in post. I’m also OK to buy Tahoma Switch and use it’s local API but need to know it really works otherwise it’s expensive “brick” for me.
Using the Homekit Integration of HA
I do not own any apple devices this all is done using HAs HomeKit Controller, which pops up automatically if HA and the device is in the same subnet.
Perfect. It looks really positive. Thanks. Going to order
As I said, works for me for 2 weeks now.
I even migrated from the Tahoma Switch to the Connectivity Kit without problems (except the standard somfy weirdness )
Good luck
Well, just ordered.
I’m using the HomeKit integration with Somfy for about 2 months now and I did not have a single outage. Be aware, there is no stop functionality for the covers. You can open and close them, but you can’t stop in between. Workaround is to use the cover.set_cover_position service.
Also, tilt functionality is currently not given.
So Connectivity kit just arrived,
initial setting via android application went fine, it discovered all my blinds, it has appeared into Home Assistant, but is impossible to add it into Home Assistant since failing when I’m trying to enter PIN from box (or from backside label). I’ve tried to enter in format as is on box 2xx1-3xx6-0xx5 as well as in 2xxxxxxxxx5 but Home Assistant still reports “Wrong HomeKit code”.
You could try to configure the Overkiz component from core, than look at your gateway and check if you see the same HomeKit code.
This is part of diagnostic data. There is code in format “SETUP-2xx1-3xx6-0xx5” but it wasn’t accepted as well.

I wasn’t referring to your diagnostic data. Did you check if you have the HomeKit sensor? Pick your gateway from the list and see if it shows a code. In my format it is xxx-xx-xxx.
No, I have overkiz integration and there is no sensor. There are just blinds and Connectivity kit. But even I choos Connectivity kit details there is nothing related HomeKit.
And I can’t use HomeKit due to unable to enter PIN.
Ok, so I have looked at my setup and I do not see a HomeKit PIN with the overkiz integration. So there is no entity available for me neither.
Anyhow, when I was adding the Tahoma Switch as well as the Connectivity Kit, I got an error message when entering the Setup Code too. Cannot recall what it was. I closed the window and the integration was setup correctly and working, so I did not bother much.
This happened on the Switch as well as on the Connectivity Kit.
I must also say, that I created a scene on the Switch before starting the process (was mentioned on github to do so) but not on the Connectivity Kit. Did not change anything.
Thanks Herbert,
I’ve awaited your response with high hope to getting solution of that but it’s not working in my case.
Currently have no idea what to check or try in next step. I really trust that IP printed on backside label or on paper box is really correct and problem is maybe in some incapability or exception between HomeAssistant HomeKit implementation and Connectivity kit.
Overkiz works fine at least and it’s fine work around for me.
perhaps @imick can fix the problem with the homekit sensor in an upcoming release. This would at least allow you to verify whats on the box and whats inside the connectivity kit and if both homekit setup codes are the same and which is correct.
