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. #homeassistant #esp32 #maker #pcb #olimex #poe #esphome
