Plugin to control Dooya DC tubular motors

Plugin for pimatic to support DC tubular motors used in motorized roller blinds made by Chinese company Dooya and other vendors (like AKKO) who use the same chipset. Requires 433,92 MHz transmitter connected to raspberry pi.

The plugin emulates 433 MHz remote control including "up", "down" and "stop" buttons, so you will need actual values from a remote to replicate. You can't teach a receiver an additional remote because it can only hold one at a time.

Installation

npm install pimatic-dooya

Important: if you do not run pimatic as root your user must be a member of the gpio group, and you may need to configure udev with the following rule (assuming Raspberry Pi 3):

$ cat >/etc/udev/rules.d/20-gpiomem.rules <<EOF
SUBSYSTEM=="bcm2835-gpiomem", KERNEL=="gpiomem", GROUP="gpio", MODE="0660"
EOF

This plugin uses physical pin numbering so by default pin 22 is used which is GPIO25 pin for raspberry pi 3.

Codes

Codes for commands are coded with four pulses which is different from most 433 MHz chipsets. Consider the following image as a reference.

pulse codes

First goes remote id 32bit sequence which is hardcoded within the chipset then the actual command. Also note that a rotary command (in either direction) takes two different sequential commands to execute.

Usage

Plugin does not provide any interface. Instead it supports default shutter actions move up, move down, stop as well as shortcuts raise and lower. Feel free to create rules with them to your heart's content.
