HTCC

This gem is a Ruby client for the Honeywell Total Connect Comfort API.

I have only tested it with the Honeywell Home Wi-Fi 7-Day Programmable Thermostat (RTH6580WF), but it should work with any thermostats that use Total Connect Comfort for remote control. I would be interested in knowing what other devices have for thermostat.info['DeviceType']. I'm currently initializing everything as an instance of HTCC::Thermostat.

Currently, settings and scheduling are a work in progress.

gem install htcc

You can also test it out by forking this respository and running docker-compose run htcc.

htcc = HTCC::Client.new('tcc_login@example.com', 'password')
# => #<HTCC::Client:0x0000abc123 @debug=false...>

Get first device.

thermostat = htcc.devices.first
# => #<HTCC::Thermostat:0x0000abc123 @info={"DeviceID"=>...>

Get the current ambient temperature.

thermostat.current_temperature
# => 71

Get current setpoint for heat.

thermostat.heat_setpoint
# => 70

Set the heat setpoint to desired temperature with a temporary hold. Returns to scheduled temperature at the next scheduled time.

thermostat.heat_setpoint = 72
# => 72

htcc = HTCC::Client.new('tcc_login@example.com', 'password', debug: true, debug_output: $stdout)
# => #<HTCC::Client:0x0000abc123 @debug=true...>

debug determines whether to display the HTTP request/response data (boolean, default: false)

Warning! If debug is set to true when initializing the HTCC::Client instance, it will display the login and password in plain text. You can also set debug to true after initializing the client. However, this will also display sensitive data such as cookies for every request. See Net::HTTP documentation. Use at your own risk.

debug_output sets the output stream for debugging (Used by Net::HTTP#set_debug_output, default: $stdout).

Display HTTP request/response data.

htcc.debug = true
# => true

See above warning.

Check if log in was successful.

Get current system mode. Returns :emergency_heat, :heat, :off, :cool, or :auto depending on the capabilities of your device.

thermostat.system_mode
# => :heat

# => HTCC::Thermostat::SystemError (Unknown mode: :emergency_heat. Allowed modes: [:heat, :off, :cool, :auto])

Check if the device has a fan.

thermostat.has_fan?
# => true

Check if the fan is running.

thermostat.fan_running?
# => false

Get the fan mode. Returns :auto, :on, :circulate, or :schedule depending on the capabilities of your device.

thermostat.fan_mode
# => :auto

# => HTCC::Thermostat::FanError (Unknown mode: :circulate. Allowed modes: [:auto, :on])

Get the current ambient temperature.

thermostat.current_temperature
# => 72

Get the current temperature unit ("C" or "F").

thermostat.temperature_unit
# => "F"

Get the temperature that is set for cooling.

thermostat.cool_setpoint
# => 68

Set the temperature for cooling. Uses a temporary hold that returns to scheduled temperature at the next scheduled time. Returns an HTCC:Thermostat::TemperatureError if the given temperature is out of range.

thermostat.cool_setpoint = 70
# => 70

thermostat.cool_setpoint = 32
# => HTCC::Thermostat::TemperatureError (Minimum setpoint is 50. Given: 32)

Get the cool setpoint range.

thermostat.cool_setpoint_range
# => 50..99

Get the temperature that is set for heating.

thermostat.heat_setpoint
# => 72

Set the temperature for heating. Uses a temporary hold that returns to scheduled temperature at the next scheduled time. Returns an HTCC:Thermostat::TemperatureError if the given temperature is out of range.

thermostat.heat_setpoint = 74
# => 74

thermostat.heat_setpoint = 100
# => HTCC::Thermostat::TemperatureError (Maximum setpoint is 90. Given: 100)

Get the heat setpoint range.

thermostat.heat_setpoint_range
# => 40..90

Get the current hold status. Returns :none, :temporary, or :permanent depending on the capabilities of your device.

thermostat.hold
# => :none

Set a hold. Returns an HTCC::Thermostat::HoldError if desired mode is not present.

thermostat.hold_until
# => "22:15"

Set a temporary hold until a given time. Time must be in a zero-padded 24-hour format (HH:MM). Time begin at 00:00 (midnight) to 23:45. Minutes must be in quarter hours (:00, :15, :30, :45). Returns an HTCC::Thermostat::HoldError if given time is not valid.

thermostat.hold_until = '05:45'
# => "05:45"

thermostat.hold_until = '05:46'
# => HTCC::Thermostat::HoldError (Unknown hold time: "05:46". Valid times are from 00:00 - 23:45 in 15 minute intervals.)

Clear out any holds and resume heating/cooling schedule (same as thermostat.hold = :none).
