Hi,

Thanks for this handy utility :) I managed to used it successfully with one of my AC, but then I enabled the WiFi on the second one, and the script can not start up any more. I get this traceback:

$ node index.js --mqtt-broker-url="mqtt://localhost" --mqtt-topic-prefix="home/greehvac" --hvac-host="192.168.88.255"

Does the script support more than one devices at the same time?

Unfortunately, multiple devices are not support at the moment. As a workaround, you can try to run multiple instances of the addon, as described here.
