Ambi Bridge

Control your AC with Siri on your iPhone, Mac or HomePod.

This application bridges Ambi Climate AC controllers with Apple HomeKit. With no configuration required, the App is very simple to use.

You need one Ambi Climate device per AC unit and the app needs to run on a mac in your home. Ambi Bridge takes very little processor time or resources, but it does need to be running all the time. Note, that means if your Mac is shutdown or goes to sleep, HomeKit will not be able to talk to your device until the Mac is woken again with TPL Bridge up and running. Ambi Climate also requires an internet connection too.

The App creator has no affiliation with Ambi Labs, but is just an avid user.

Their devices can be found at

Ambi Bridge will detect all your Ambi Climate devices you have set up when you log in to your Ambi Climate account. You can choose to bridge devices in one or all of your configured locations.

HomeKit supports three modes Cool, Heat and Auto, which by default correspond to Ambi Climate modes Away, Temperature and Comfort respectively. These assignments can be changed in the preferences.
