In our house, blinds are directly plugged in a Controllino. It means that physical buttons are inputs of the Controllino.
Hence, blinds are fully controlled by the blinds.ino Arduino
program, that lands in the Controllino. It sets a simple automata to
control the motor of the blinds. The code is largely documented, so
enjoy!
It also supports a remote control over TCP. It sets up a TCP server and a
specific but very basic binary protocol to control the blinds. It assumes the
Controllino is wired by RJ45 to a router with a DHCP server. Thus, the
Controllino IP is assigned dynamically by DHCP. The blinds.ino program uses
the by DHCP. The blinds.ino program uses the
Telnet port (23) to receive
data (because why not 🤷♂️).
Example of raw usage with netcat:
$ printf '%b\t%b' '\x02' '\x04' | nc 192.168.1.42 23 -v
# ^~~~ ^~~~ ^~~~~~~~~~~~ ^~
# | | | |
# | | | the port
# | | the IP
# | the action
# the subjectHopefully, there is a Rust program to
control the blinds! Please, welcome blinds. Here is a basic usage, but check
its documentation to learn more.
