Just got one of my more involved Home Assistant integrations online. We added a pressure transducer to monitor the water pressure for our pressure tank (where the well pump comes in). We have an Olimex PoE ESP32 there already and I decided to custom design and fabricate a PCB (first time ever) as a hat for an ADS1115 ADC and connectors.
It works! So we can now monitor our water pressure in excruciating real time precision. Just because.

Finally finished my home energy monitor project this afternoon. This uses the infrared port of my Elster R1S hydro meter, read by a repurposed Blueline Innovations PowerCost Monitor sensor. The R1S meter outputs a 100ms wide IR pulse for every 1mWh or energy consumed. Home Assistant uses the ESPHome pulse meter platform to convert these pulses into both power (pulse rate) and energy (pulse counts) readings. The ESP32 fit nicely into a repurposed Raspberry Pi case. #homeassistant #esphome

@zrail@hachyderm.io Interesting. I have a good home assistant setup, but I’m currently using nodered completely separately on the pi for this.
I’m just getting started with #esphome. I have a bunch of esp32s sitting around. The central nervous system of this thing is this 8-way relay. I control it with 8 GPIOs off the pi. Closing or opening a relay on the elegoo will cause 24VAC to go to the right place and make the right thing happen.
If I can put esphome on an esp32 and control all 8 relays from that, I can do all the scenes and automation in home assistant. That would be super, because the whole family is all familiar with home assistant.
Is it that simple? Pick 8 GPIOs on the esp32, and wire them up? Then just control everything in #homeassistant?
