Smoothing the temp Sensors

Smoothing sensors discussion

The temp sensors in these stoves are VERY inaccurate. I found it helpful to create a smoothing sensor to get rid of the extremes in temp fluctuations.

you can see a swing of 8 degrees here! Whereas the smoothed line evens it out. The BS error is a binary sensor value of 55 or 60 that track the Goodbye! fix so it graphs easily. this shows how many times the stove randomly turns itself off. Its just easy to visualize that way on the graph below the same scale as temps.

The house is around 60 degrees during the night bc my automation reduces the set temp at 11:30pm. at 5:30am, I set the stove to P1 and ECO2 because it takes a while for the rest of the house to heat evenly and ECO2 seems to work well in the mornings when its really cold out, as long as the automation kills the stove when it gets too warm. After an hour or more ( if its 10F outside, it can take 2 hours), the temp in the house has evened out even though the temp at the stove is much higher than set temp. I monitor temps and when (smoothed temp >= set temp + 3F), I know the room is warm enough. Then I turn it off with an "overtemp automation". This way the stove isn't cycling on and off a dozen or more times while the room regulates to a comfortable temp. At 11:30am, I set it for ECO1 and P4.

This whole routine saves cycles on the ignitor which only lasted last winter and 2 weeks of this winter and is almost $50 for a new one. I HIGHLY recommend getting a spare ignitor. Call the vendor support line and tell them yours is broken BEFORE it dies, which is inevitable. It took 2 weeks for my new one to get here "overnight".....
