Somfy-RTS-RollerShutter-Control-via-ESPhome

This is mainly based on the articel but I had some issues and adopted on some points as well as documented it for my needs.

Roller Shutter sniffing

Hardware required:

• Ubuntu 20.04 Distribution or something similar
• RTL-SDR Sniffer e.g. Sniffer

Basic Software required (from blank ubuntu):

• net-tools for IP detection and ssh access
• git for git Data
• build-essential for make
• rtl-sdr to detect the HW

sudo apt install net-tools
sudo apt install ssh
sudo apt install git
sudo apt install build-essential
sudo apt install rtl-sdr

RTL-SDR Preparation:

• Clone Repository
• make C Files

git clone https://github.com/dimhoff/radio_stuff
cd radio_stuff/
make -C converters am_to_ook
make -C decoders decode_somfy

RTL-SDR Sniffing:

sudo  rtl_fm -M am -f 433.42M -s 270K | converters/am_to_ook -d 10 -t 2000 -  | decoders/decode_somfy

Hardware Preparation

• ESP8266 or derivate
• TI-CC1101

Wiring

I use the NodeMCU V3 which have the same config as the D1 mini. and the new TI-CC1101 design:

ESP32	TI CC1101
GPIO2	GD00 3
GPIO4	GD02 8
GPIO18	SCK 5
3V3	VCC 2
GPIO23	MOSI 6
GPIO19	MISO 7
GPIO5	CSN/CKN 4
GND	GND 1

ESPHome Software Config

• Install in HomeAssistant Settings->Addon -> ESPHome
• Connect ESP8266 to the PC for initial Flashing
  • I used https://web.esphome.io/ with initial Flashing to get the ESP8266 into HomeAssistant
