You typically use ESPHome with Home Assistant, but you can also connect it to other systems such as Node-RED or just have it as a stand-alone device.

ESPHome is perfect for building DIY Sensors.

I'm going to use the MQTT and HTTP ESPHome components to connect a sensor to Node-RED without the need to Home Assistant.
