Quick step-by-step guide on assembling an IR receiver for reading IR codes from your remotes based on Wemos D1 mini, Wemos IR shield, and using ESPHome.

My living room multimedia setup consists of numerous devices with varying degrees of stupidity. I’m chasing to improve it adding additional DIY hardware and functionality not always because of hate of TV remotes but also because I’m in love with IoT and soldering. First, I’ve added WiFi power control to my Cambridge Audio amplifier, then I’ve implemented WiFi-to-IR remote control to the TV. Then I decided to improve sound quality from TV and added a DAC between the TV and the amplifier. It is connected to the TV via Toslink optical cable. And it broke my volume control because you can’t change the volume on a digital output port on a TV, you forced to rotate the knob on amplifier instead.

Previously I was using JBL Bar connected to a TV in my living room. It was controlled with WiFi IR bridge, so whenever my Chromecast or PS4 was in playing state, the Bar was turned on and ready.

Now I have passive speakers with a simple integrated amplifier, and it can’t be turned on or off without physical interaction. You need to press and release the button on the front panel to toggle amplifier power. So today we will add WiFi power control to Cambridge Audion AXA25 integrated amplifier.

Many modern TVs can be controlled not only with an IR remote. Many could be easily integrated with Home Assistant or any other smart home solution. Samsung smart TVs, LG with WebOS… But what if your TV is so dumb it even don’t have WiFi or Bluetooth? Today we’ll add WiFi control to an old and dumb Samsung TV with a little help from ESPHome.

So there was a simple air humidifier… Actually, this post is a good example of how to make your regular boring home appliance a little smarter. The main part of my humidifier will be the Wemos (or Lolin) D1 mini board based on the ESP8266 WiFi chip.
