Pellet level using ultrasonic sensor

[jazzmonger]

It’s been challenging but I’m finally turning the corner of taming this sensor. It seems to be very stable if the stove is off, but while it’s operating, the noise introduced in the signal is brutal. Here’s a trace of the raw sensor and then after I apply a smoothing algorithm using a Lambda in the Plotly graphing library, which seems to be the only way I can get a useable signal.

I’ll need help translating the plotly lambda to an edphome filter as my lambda writing skills suck!!
