[BUG] Thermostat causes Node-RED to crash

I have bought a controller which can control my climate. I want to represent this as a Thermostat in HomeKit.

However I’m running into issues. I can’t really figure out why this happens. It seems that changing state works (but sometimes not), but if I try to change the temp, the device in HomeKit immediately says that ‘No Response’ and sometimes Node-RED also quit and restarts…

Why this happens? Someone can have a look at it what I might miss during the config?

My config:

@radokristof Please take a look #88

My assumption was right. The problem was not in HomeKit, but in openHAB (and also some little bugs in the function nodes transforming the states). Problem solved.
