Homebridge Broadlink RM Pro w/ Fahrenheit temperatures for air conditioners

Jiehan's fork

Installation:

npm install git+https://github.com/jiehanzheng/homebridge-broadlink-rm.git

I tried to submit a pull request which was was ignored. So unfortunately I will be using this fork moving forward. Here is what this fork does:

Context

My IR remote control PAR-SL100A-E controls the AC in 1 degree Fahrenheit increments (approximately 0.5 degrees Celsius).

This plugin currently sets a minStep of 1, so Home app will only send integer target temperatures in Celsius. This conversion causes the Home app to "skip" many Fahrenheit set points.

I want to make available to HomeKit every Fahrenheit set point that my IR remote control supports.

Proposed approach

Allow temperature with decimal points in the data JSON map
If decimal points are detected in the config, set minStep to 0.1 to allow HomeKit to send more accurate target temperatures
Add fuzzy matching logic inside getTemperatureHexData when it is doing the lookup:
- Find the closest match temperature with the correct prefix in the data JSON
- If the temperature difference is less than 1 degree Celsius, return hex code for the closest defined temperature
- Otherwise return null (have getTemperatureHexData handle this as usual)

Sample config

                    "data": {
                        "off": "26006c...",
                        "temperature24.4": {
                            "data": "26006c...",
                            "pseudo-mode": "cool"
                        },
                        "temperature20.6": {
                            "data": "26006c...",
                            "pseudo-mode": "heat"
                        },
                        "heat17.2": {
                          // ...

If the plugin is unable to discover your device, it's likely you've locked the device with the cloud so it no longer accepts local connections. In this case, follow these steps:

Open the Broadlink app
From the Home screen, tap on your Broadlink device
Tap the ... in the top right
Scroll down and toggle "Lock device" to Off
Tap OK when prompted "Confirm to unlock the device"

This plugin should now be able to discover your device.
