There are lots of smart home systems that will let you blast your older dumb appliances with infrared to control them. However, many are tied to ugly cloud systems that can frustrate you on a regular basis. [Steelcuts] whipped up a cloudless solution to this problem instead.
IR2MQTT does pretty much exactly what it says in the name. It allows integrating things like air conditioners and televisions into a Home Assistant setup with the use of an IR blaster and a neat, tidy web app. You use it with an ESP32 or ESP8266 running a firmware based on ESPHome to actually do the IR blasting. In turn, IR2MQTT is a back-end plus a web interface that lets you setup all your IR devices without having to manually capture IR codes and create YAML files to do everything. It’s also integrated with large databases of IR codes for common appliances so in many cases, you can just look up your gear and get it working the easy way.
Sometimes all you need to get the job done is an IR LED and the will to use it. If you’re cooking up your own infrared hacks, don’t hesitate to let us know on the tipsline.
