Remote home appliance controller based on Raspberry Pi and web interface

A project that uses a web page to remotely control the Raspberry Pi to send out infrared signals to control home appliances such as air conditioners. To put it simply, you can use your mobile phone to control it through the web page on the way home, turn on the air conditioner in advance, and set it to the required temperature. At the same time, the indoor temperature and humidity can be monitored in real time on the web page. The entire project is written based on Python's flask framework.
