homebridge-infinitude

Infinitude Plugin for Homebridge. Enable Carrier/Bryant Infinity Touch Thermostats in HomeKit.

What is Infinitude? Infinitude is an alternative web service for Carrier Infinity Touch and other compatible thermostats. It allows read and control of your Infinity system locally over your network (no serial connection needed).

Behavior

This plugin will create thermostat accessories for each enabled zone in infinitude.

• In OFF mode, it will set infinitude activity for that zone to off, unless shutOffAway is true.
• In HEAT or COOL mode, it will set infinitude activity to the set temperature in the relevant mode.
• In AUTO mode, it will set infinitude activity for that zone to Auto to automatically adjust between heating and cooling points. This implementation currently is not working fully.
• If you have a thermostat schedule, the temperature change will be made temporarily within the current profile using the plugin's holdUntilvalue.

Other settings:

• If holdUntil is specified, it will set otmr to the specified hour.

HomeKit Features:

• Thermostat Control: Set Target Temperature for Heat & Cooling. Infinitude values htsp and clsp respectively.
• Current Temperature: Dislays current temperature reported by the zone thermostat. Infinitude values rt
• Hardware Display Unit: control temperature unit (Celcius/Fahrenheit) of physical Theromstat.
• Filter Life Level: Displays life of Filter, 100 being brand new and 0 needing replacement. Infinitude value filtrlvl
• Current Relative Humidity: Displays indoor humidity reported by Thermostat. Infinitude value rh
• Mode Switches: Change Infinity Thermostat modes with HomeKit switches (Optional) (Not Ready Yet)
• Fan: Currently provides data on whether the fan is On or Off. Control is Read/Write - HOWEVER, Infinitude does not provide a way to determine if a Fan is running under Auto or Manual. Suggested use with caution and temporary overrides only, allowing Infinity to properly control the fan.
• Outdoor Temperature Sensor: Adds Temperature Sensor to use Infinity Outdoor temperature for home automation. Uses OAT value.
• Temperature Data History: Uses the fakegato library to store data history in HomeKit. Visible only in Eve For HomeKit app.

Local Control

If you want to keep your IOT devices completely local, you can accomplish this with Infinitude. The carrier web services seem harmless, but local control is often a desirable preference for speed, reliability, and future-proofing against cloud services being sunset. To support local-only control, you will need to use your firewall to block access from your Infinitude Client to the following hostnames:

• legacy.api.iot.carrier.com
• www.api.ing.carrier.com

Local communication between your Thermostat-Infinitude-HomeKit will function, but the Carrier and other official apps will no longer work.

Useful HomeKit Automations / Scenes Ideas:

You can use HomeKit to completely control your thermostat's schedule.

Scenes - Use scenes to create desired temperature profiles for both Heat & Cool, e.g.,:

• Climate Home - desired settings for during the day when I am home.
• Climate Away - desired settings for while the house is empty.
• Climate Sleep - desired settings for while we sleep.

Automations - Use time and location based Automations to trigger my scenes. e.g.,:

• At 6:00 AM - Climate Home
• At 11:00 PM - Climate Sleep
• When Last Person Leaves - Climate Away
• When First Person Arrives - Climate Home

Shortcuts - Use personal automations in Shortcuts for advanced functions like Air Filter Reminders:
