Roller Shutter 433mhz - Status Reflection

[Norik_Krasniqi (knock)]

Hey Community,

I got a tubular motor and installed the hardware today to control my roller shutters (see pics below). The remote has three buttons (up, stop, down - see pic below) and all the RF codes can be learned through Broadlink RM Pro (which I have).

Is there a way to get the position status of my roller shutters?

I was thinking to get a RF receiver and connect to Raspberry Pi, where my HA is installed but I am not sure if I would be able to know the position of the roller shutters even then?

I would really appreciate your feedback.

If it’s RF you don’t get any feedback so it’s not possible to know what the position is except at either end. You could use time to semi-determine the position but it wouldn’t be very accurate. You could maybe fit a hall effect transistor and a magnet to get position data but it would probably be quite difficult. You really need a stepper motor to do precise positioning.

Hi , this is similar to your system but its for an older version of Home Assistant
https://rollertrol.com/raspberry-pi-smart-home-with-home-assistant-and-broadlink-part3
i have modified-t to pass config check but did not tested on actual rollers
it works as apackage
