> ESPHome just automates all the super tedious parts of working with esp32s (stuff like connecting to wifi, MQTT, OTA upgrades, logging to mqtt, etc), without sacrificing any power. I write my own firmware for all of my ESP devices and I can confirm, those definitely are the bulk of the work. The latest one (for a relay to power cycle my modem if the internet goes down) took less than an hour to write since I was able to copy-paste all of that boilerplate from a previous project.

It would probably take 5 minutes to configure from scratch ESPHome, less time if you're copying from an existing config. In addition to that, you get automatic logging into Home Assistant and deep integration for free. Using Hypfer's discovery[1] that you could read the raw values from Ikea's Vindriktning using an ESP, I wrote an ESPHome script for an ESP01 that pipes the data into Home Assistant. Now when I'm cooking and the air quality gets too bad my HVAC fan kicks on to clear the air. It took longer to solder everything up than it did to "code".

  That’s pretty cool! If I had know about ESPHome when I first got into home automation I’d probably have gone with it. Although I’m kind of glad I didn’t because I actually really enjoy programming in C++.

FYI this could have been done really easily in esphome: switch: - platform: gpio pin: 25 name: "Modem relay" restore_state: ALWAYS_ON id: modem_relay interval: - interval: 1min if: condition: not: wifi.connected then: - switch.turn_off: modem_relay - delay: 1s - switch.turn_on: modem_relay

  Mostly I write my own firmware to improve my C++ skills :)
