Thermostat controlled pellet stove relay.
Ultrasonic pellet fuel hopper level sensor.
Thought it would be nice to see if the Wood heat Pellet stove needed pellets at any time and be able to automate when low.
I already had a low volt relay connected to the stove for a thermostat control integrated with my Schedy heating schedule using input Boolean occupancy detection so I just needed to swap out the old relay with a D1 mini and a relay shield and just because I could I added a DS18B20 temperature shield. (but it is reading high because it located behind the pellet stove).
D1 mini 5$
D1 mini relay shield 2$
D1 mini DS18B20 temperature sensor shield 2.50$
Ultrasonic Module HC-SR04 Distance Sensor 2$
Temporary project box until I 3D print a new box to fit all the components.

My background. I have been using sonoff devices and ewelink with IFTTT for about 3 years to automate my home and heating and evaporative cooler. I made the jump to HA and I have been playing with Home assistant since 2018. I’m enjoying playing with WLED I made a automatic fish feeder also.
Over 30 years I have been installing and servicing Hearth products specializing in Gas and wood pellet burning stoves.
Home automation is a hobby I needed.
