Hardwired Motorized Shades

Hardware
1

I’m looking into options for motorized shades in a house currently under construction. These shades need to be hardwired. No cords hanging out or running down and plugging into an outlet. I would also prefer something that is not cloud based. The house is also 10,000 Sq. Feet so Zigbee and Z-Wave aren’t really an option considering their range limitations.

If there was something that would work using POE, that would be optimal, but PowerShades is the only company I can find that offers something like this and I don’t think they integrate into HA. Is there any way to get shades to operate over a wired internet connection?

Another option that I was exploring is using the Shelly 2.5 relay. Does anybody have recommendations for shades that work well with that? It’s not a wired internet connection, but this seems to fulfill the rest of my requirements.

So I’ve read up a lot on Somfy, but it seems to me like their wired options are limited to SDN. They do have a product called the Universal Automation Interface Plus which converts everything to IP where you can plug into a switch and Windows Networks can discover it. But I just can’t figure out if this connects to the Somfy MyLink app somehow. Since this is new construction, I really don’t want to rely on RTS, Zigbee, or Z-Wave when pulling wire is so easy. Does anybody know if the UAI Plus has any remote functionality?

HI, I am in the same predicament! ever found a good solution?

Yes. I wrote a library that implements the SDN protocol (it’s RS-485 based): python-somfy · PyPI I highly recommend these shades if you can do a hard-wired installation. They are rock-solid.

I’m now working on adding integration into HA. I’d used my own Somfy-to-ZWave gateway before.

Hi,

I have been following your work and thank you for your efforts on this.

I am weeks away from having to decide between Somfy wired with UAI plus, or Somfy wireless (I presume RTS). I did not find SDN on the Integrations of HomeAssistant. Just curious if you are still working on that, and what would you recommend I choose for shades?

My concern would be I get the wired solution and that I wouldn’t be able to integrate into HA.

Thanks so much for your efforts on this!

I have completed the integration, and it works! I’ll submit a PR into HA soon.

Meanwhile, you can download this directory: somfy-sdn/homeassistant/components/somfy_sdn at adding-somfy-sdn · Cyberax/somfy-sdn · GitHub and place it into your ‘custom_components’.

Wow - incredible! Thanks so much for this! I’m sure many people will benefit from this integration.

Thanks Cyberax for your work on this. I’ve been looking for Somfy SDN for a while. Has anyone who added this into the custom_components folder successfully set it up? If so, how is it configured once it is added?
