Question about Somfy integration

[frail lava]

Hi, I have several blinds in my home that are controlled with Somfy remotes. However, I don't have a Somfy hub. Also these somfy hubs are pretty expensive and I've hear they are not that good. So I'm considering trying to automate them directly. I've seen some mentions of being able to make or buy devices to simulate the radio signals and control that using HA. Does anyone have more information on how to do that and where I can get the needed hardware to do this? Preferably a solution where I don't need to use a soldering iron.

Thanks!

Do you know what technology is used to control your Somfy blinds?

I use this, and it’s great. Cheap and easy to build: https://github.com/rstrouse/ESPSomfy-RTS-HA

If I try adding that it says I need the 'hacs' integration to do this? How do I do that?

When I try to use the 'add to HA' link in the page above I get this error:

This translates to:

This redirect is not supported by your Home Assistant instance. You need the hacs integration to use this redirect.

And if I then click on 'hacs' I get:
Oh no! This page does not exist 😞

You don’t necessarily need it. You build the physical device, flash the firmware, and then to integrate it you can install this as a custom component (many people use HACS, I do not), or you can integrate it using MQTT without a custom component.

Basically, start here: https://github.com/rstrouse/ESPSomfy-RTS

Get the device working, then connect it to HASS using the component or MQTT.

The firmware of what?

Not sure I understand what the 'physical device' is you are talking about here

[runic helm]

This is an ESP32 project you can build that will interface directly with Somfy shades using the radio, just like a remote will.

You were asking for information on how to make a device that will control the shades directly. This is it.

ah ok like that. Thanks. I'll check it out

So lets say I have this https://www.amazon.com.be/-/nl/AZDelivery-Dev-Kit-V4-compatibel/dp/B07Z83MF5W/ref=sr_1_8?crid=NVEQUZBMPAQG&dib=eyJ2IjoiMSJ9.94BJ8dYa4MAg13v6uuGjUjkz1yyCMKfZE99hxikHUTOWQr7bQfz4u1YCzqsbju7MGMCXnc3VpbVOW9qa4tLNXfNHfgVbUIlsBoSc6pbntXEjBbcoDX7HuN23oAr1jj5iWcQpO7h3nPcFeneM8MJZzJrUVhsyA8D-jxyZTFMmOAiIA9GKV7feRRtRXRB54k5jZBKJMNIUSz252baeKmM4lUmzFNMkRuv89DE3EarNmhQad_n1JWmENbFptFPoJkqX3Y14dH5SBGU_Oe1dIcFKIzJ0oi39kivpxTzjBIhQyleCRRgObleU9Xhx-g5mXEtceU6aXmyYQdHBlO-uNwjgJKezBaxjHcBLzFk0po8eTzhjn_s9qzX-kruyG-uFSLPNXfV-mMiBJi3CQiVOcMeM7BEoGiff1X-hhf5iUMDoFYYq_TrWo5iyDiildRTpjSqE.W1uScagcvnMgMkyi420gFOEoTsBilG9hyfblf5XfQI0&dib_tag=se&keywords=esp32&qid=1734322298&sprefix=esp32%2Caps%2C80&sr=8-8&th=1 for the ESP32 board, this https://www.amazon.com.be/-/nl/gp/product/B0D3T1Z55C/ref=ox_sc_act_title_2?smid=A1SUKMSS7M6D1M&psc=1 for the CC1101, would this be a good and usable combination for this?

Ugh, those links are ugly

[frail lava]

Or I think I can actually power that ESP32 through the USB-C connector

[runic helm]

Looks a lot like what I bought, yea. I had the feather ESP32 and this radio: https://a.co/d/hIyG4jU

And, yea. I power using a USB cable and a wall plug so I don’t need batteries.

Oh, and nice thing about those is you can use those wires that can just plug into their leads so you don’t need to solder.
