I’m using the “RM Bridge” app with the site at http://rm-bridge.fun2code.de/rm_manage/code_learning.html - it’s the method as described by Cato early on in this thread, but I’ll summarise it here, for example turning on my air conditioner:
- Power on my RM3 Mini
- Turn on the RM Bridge app on my phone (running on the same Wifi network)
- Visit the above site, and enter the URL that the phone displays
- Hit Load Devices => my RM3 comes up (check the MAC address to be certain)
- Hit Learn Code and press the desired button on my aircon remote control, while pointing it at both the aircon unit and the RM3
- The aircon unit beeps, so I know the IR command was sent
- A couple of seconds later, the website pops open the code area
- I select the “code” section of the text and copy it to the clipboard
- I switch to my terminal window where I have a vim session open, editing broadlink.map
- I enter
AIRCON_ON =and then paste the code in
Repeat for each command. The only real trick is making sure you copy the code completely into the broadlink.map file. If you miss a character, the Broadlink binding won’t be able to send it and you’ll see an error in the logs.
