Not working401 Unauthorized; user concludes S40 cannot be integrated, even via Alexa
Saved copy
This is on a Synology NAS. The end goal is to integrate my Lennox S40 thermostat into Apple's Homekit. However, after running to everything I've found online, it just isn't possible w/ the S40 thermostat. I've even tried to "backdoor" it through the Amazon Alexa app (which it is compatible with) and that doesn't work either.

Each row is one report from a plugin’s GitHub issues, pull requests, discussions, wiki or docs, or from r/homebridge. Check the date and the linked thread before you buy.

In ReReHome

Once a Homebridge plugin publishes it, this device reaches Apple Home as a HomeKit accessory behind your Homebridge bridge, so ReReHome shows and controls it like any other.
