Home assistant Custom component for Pax Calima fan

This is offered AS IS. Feel free to fork. Developed and tested in HA version 0.108.9.

This only works til v.2022.6. v.2022.7 uses python 3.10 and the bluetooth library used does not work wit it. You should check https://github.com/eriknn/ha-pax_ble

Installation

1. First install pycalima

#Get the latest to your work directory 
wget https://github.com/PatrickE94/pycalima/archive/master.zip
unzip master.zip
cd pycalima-master

#Install as python package
# cmdline.py is in wrong directory, move it
mv cmdline.py pycalima

Pycalima doesn't return Mode properly so fix this from Calima.py

    def getMode(self):
        v = unpack('<B', self._readUUID(CHARACTERISTIC_MODE))
        if v == 0:
            return "MultiMode"
        elif v == 1:
            return "DraftShutterMode"
        elif v == 2:
            return "WallSwitchExtendedRuntimeMode"
        elif v == 3:
            return "WallSwitchNoExtendedRuntimeMode"
        elif v == 4:
            return "HeatDistributionMode"

Replace with

    def getMode(self):
        v = unpack('<B', self._readUUID(CHARACTERISTIC_MODE))
        if v[0] == 0:
            return "MultiMode"
        elif v[0] == 1:
            return "DraftShutterMode"
        elif v[0] == 2:
            return "WallSwitchExtendedRuntimeMode"
        elif v[0] == 3:
            return "WallSwitchNoExtendedRuntimeMode"
        elif v[0] == 4:
            return "HeatDistributionMode"

And install package

pip3 install . 
# README.rst mentions run.py but this version does not have it. Check it from other forks

# now calima cmdline works
calima -h

1. Find out the MAC address and pin of your Pax Calima with calima -s. Pin code is in you fans motor unit.
2. Put init.py, sensor.py, manifest.json into /custom_components/paxcalima/ on your home assistant installation (where is the directory where your config file resides).
3. Add the following to your configuration.yaml (or modify your sensor heading, if you already have one):

sensor:
  - platform: paxcalima
    mac: 00:11:22:AA:BB:CC # replace with MAC of your Pax Calima 
    pin: 57854677 # Replace with you pin code
    name: Projector Room(optional)

Then restart Home Assistant and if everything works, you'll have some new sensors.
