I have some of those mini-split Fujitsu heat pumps in my house that have infrared (IR) remote controls. This post explains how I set up my smart house to be able to automate the heat and air conditioning with a raspberry pi and Home Assistant. <\/p>\n\n\n\n

\"\"<\/a>
The Home Assistant control panel<\/figcaption><\/figure><\/div>\n\n\n\n\n\n\n\n

In a past residence, I had done something similar with a portable floor-unit A\/C, and that post really is a prerequisite to this one. See: Adding IR send and receive capabilities to my home-assistant based smart home<\/a><\/p>\n\n\n\n

Given that exact IR LED setup (the receive circuit is not necessary), I had to find the lirc configuration for the air conditioner. This time, one already existed<\/a>. I loaded up the config from that repo into my \/etc\/lirc\/lirc.config.d\/<\/code> directory and renamed it to fujitsu.conf<\/code> and restarted the lirc<\/code> daemon. <\/p>\n\n\n\n

Then I tested it out while pointing the IR led at the wall unit:<\/p>\n\n\n\n

irsend send_once fujitsu_heat_ac heat-high-70F<\/pre>\n\n\n\n
“Beep beep!” Nice. It totally works. <\/p>\n\n\n\n
So then I hopped into Home Assistant configuration and made some input_selects and an input slider to specify the operation mode, fan mode, and target temperature:<\/p>\n\n\n\n
input_number:\n  ac_temperature:\n    name: Heatpump Temperature\n    initial: 68\n    min: 64\n    max: 88\n    step: 2\n\ninput_select:                                                                                            \n  heatpump_fan:\n    name: Turn on Fan\n    options:\n     - Auto\n     - Quiet\n     - Low\n     - Medium\n     - High\n    initial: Medium\n    icon: mdi:weather-snowy\n  heatpump_mode:\n    name: Heatpump mode\n    options:\n     - Cool\n     - Heat\n     - Dry\n     - Fan\n    initial: Heat\n    icon: mdi:weather-snowy\n<\/pre>\n\n\n\n
Then we need some templated shell commands to package up the values of the input selects\/sliders and send them off to the raspberry pi and then to lirc. <\/p>\n\n\n\n
shell_command:\n  ac_on: ssh pi@pi3 irsend SEND_ONCE fujitsu_heat_ac cool-on                                         \n  ac_off: ssh pi@pi3 irsend SEND_ONCE fujitsu_heat_ac turn-off\n  set_ac_to_slider: 'ssh pi@pi3 irsend SEND_ONCE fujitsu_heat_ac {{states.input_select.heatpump_mode.state|lower}}-{{states.input_select.heatpump_fan.state|lower}}-{{states.input_number.ac_temperature.state|int}}F'\n  set_ac_fan: 'ssh pi@pi3 irsend SEND_ONCE fujitsu_heat_ac fan-{{states.input_select.heatpump_fan.state|lower}}-64F'\n<\/pre>\n\n\n\n
And then I just added those new entities to Lovelace using the GUI, as shown at the top of the post. <\/p>\n\n\n\n
Finally I just made sure the LED from the raspberry pi was in a place where it had good line of sight with the unit, and that was that!<\/p>\n\n\n\n
I’ll add some automations to turn the temperature up and down at night later on, but so far I’m pretty happy with this. <\/p>\n","protected":false},"excerpt":{"rendered":"
