Successfully Integrating Broadlink RM Mini 3 with HASS.IO for Air Conditioning Control

After struggling for weeks to get my Broadlink RM Mini 3 to control my Viessmann Vitoclima 300-S air conditioner in HASS.IO, I’m thrilled to share my success story! Initially, I could only turn the AC on, but not off, which was incredibly frustrating. I used the Broadlink Manager to learn the codes, which worked perfectly, but replicating that in HASS.IO was a puzzle.

Here’s what I did: I carefully followed the configuration steps, ensuring the MAC address and host were correctly entered. I also made sure to use the exact command_on and command_off codes from Broadlink Manager. The key was testing each part incrementally—first ensuring the switch entity was recognized, then verifying the on/off commands.

A huge tip for anyone facing similar issues: use the developer tools in HASS.IO to monitor the state changes and logs. This helped me identify a minor timing issue in my automation. Once I adjusted the delays, everything worked like clockwork!

Now, I have a seamless setup where I can control my AC through the HASS.IO interface, complete with custom scripts for turning it on and off. It’s a relief to have this integration working smoothly, and I’m excited to expand my smart home setup further. If anyone else is tackling this, stay persistent—it’s worth the effort!
