📦 ESPHome Components

We've released ESPHome components for all of our sensor modules. Have a look at them on GitHub. There are lots of example YAMLs to go through there as well. It makes it incredibly easy to get a fully working device, from hardware all the way to automations, stored metrics, and nice graphs on your desktop.

For our 🌱 EC+pH Kit, take a look at the example_ec_ph_dallas YAML.

Change the pin for the DS18B20 probe and your I2C pins and that's it. With that, you get water temperature, conductivity, and pH measurements. You can also calibrate so everything can be done through Home Assistant.

A big thanks to Pascal Vizeli and Jesse Hills for porting our older sensors to ESPHome. They were a great starting point for these components.
