HeaterCooler Accessory: Cooler only = No Response in Home App

[Matsuo3rd]

Describe the bug Using Heater/Cooler accessory with settings reflecting a "Cooler only" setup is showing "No Response" for the accessory in iOS Home App. Adding dummy Heating settings makes the trick. However, it does not meet my expectations for a "Cooler only" device. My setup is actually a controlled Fan + temperature sensor (both Zwave) that I want to merge in a single accessory.

Expected behavior Looking at the documentation https://github.com/steilerDev/homebridge-openhab2-complete#heatercooler, it looks like one can define a Cooling-only (or Heating-only) setup by omitting heatingItem/heatingThresholdTempItem/modeItem.

Thanks @Matsuo3rd !!! I thought I go mad with this! Looking for 2 weeks for a solution.

With your config, now this works for me too. Seems to be a little bug, because the readme is saying that the heatItem etc. is optional 😉

Hi All, I have just found the bug causing this (bloody bind statements in nodejs). You should be able to remove the dummy with the next release (1.1.1), which will also remove the option to select an heating mode when there is only a cooling item (See current wip on the master branch's readme for the thermostat, i'll replicate that for the heater/cooler).

Fixed with 1.3.0
