@zebmina did you attach an antenna to both the transmitter and the receiver? Also, your radios are very close together, so the receiver might saturate (but that would be the next hurdle, first you need to receive something)

I have two Dooya motors DT82TN with a DC2760 remote control, which is 433MHz. After a lot of investigations and experiments, I got them working with Domoticz (running on a Raspberry Pi), using the following: A Broadlink RM2 (RM Pro+) which supports 433MHz. The official Broadlink app is cloudbased and can "learn" the codes to operate the Dooya, but I abandoned this since I want integration with my domotica system, not just another app on my phone. The software at https://github.com/mjg59/python-broadlink works with Broadlink devices, but does not integrate well with the RM2. So, I only use this for my thermostat, not for the Dooya curtains. The "official" Domoticz plugin described at https://www.domoticz.com/wiki/Plugins/BroadlinkRM2.html is an old version, that is not supported any more - as stated at the top of the page. The "zak45" Domoticz plugin that works is described at https://www.domoticz.com/forum/viewtopic.php?f=65&t=33223#p251517 to be downloaded at zak45's Nextcloud drive: https://synnas.publicvm.com:4430/s/Czn9r8G8QwrZ7ji This latter plugin is not easy to use, and has special added webpages to Domoticz. It is however able to use the RM2 to "learn" IR and RF codes from the UI of Domoticz. However, there is a bug due to which the learning of RF codes does not work from the UI. I was able to use the command line on the RaspberryPi with the above given plugins to detect Broadlink devices. And this way, I could also learn the 4 RF codes I needed for my 2 curtains: open/close for each. This gave me the code as some numbers, which I stored in a text file. Since the IR learning works, I used this to learn 4 commands, and then looked where these codes were stored on the Raspberry, and replaced them with the RF codes. This was easy. Just a tip: I used Dolphin with fish://raspberrypi/ to browse and edit the files on the Raspberry from my desktop PC.

@hek : Many thanks! I can do the math to do a pulley system, but that is dependent on the size of the motor, yes? What would you think the minimum size of motor I should start with? Do I need to go to a 24VDC motor, or can I do something with 5VDC motor? Regards..
