Integrating Home Assistant, ESPHome and IR Blaster protocols #ESP8266 #HomeAssistant #HomeAutomation

e dabbles describes having an old Yamaha RX-V630 receiver and an older RCA 4K TV which are missing remotes. They wanted to replace them with an ESP8266-based infrared blaster connected to Home Assistant. But there were issues.

  1. The TV did not respond to remote_trasmitter.transmit_sony power toggle command
  2. The IR range was only a couple of feet
  3. Rotary encoder events queueing up instead of only executing while rotation is active
  4. Using ESP pullup resistors for rotary encoder reading produced faulty square wave

See how these were overcome in the post here.
