Ability to Filter or Smooth the Output #1

First off, thank you to EverythingSmartHome for putting this together. I have implemented this project and it works perfectly 99% of the time. I am experiencing large (>100Kg) spikes with no weight on the bed. Home Assistant reports these spike as occurring for less than a minute. Assuming I have not done something wrong (which takes a leap of faith on my part), do you have any suggestions for smoothing out these outlier readings?

Thanks in advance for all the time and effort!

No problem, so glad you got everything working!

How often are you sending data to Home Assistant at the moment? I have seen something like this but not for as long as a minute, just one reading can spike then come down which makes it easy to ignore.

I have left the default that was in your code. So, I believe it is three seconds. I was guessing regarding the duration of the spike; it may be far less than a minute. I have attached a screenshot from home assistant. The bed was not touched during the timeline shown. Assuming I am only receiving a single errant reading, how should I go about ignoring it? Thanks again.

That looks excellent well done! I believe it is a single reading, so if you do not need the readings to be every 3 seconds, I'd suggest maybe going for 10 seconds or more depending on how often you need readings. Try 10 seconds if suitable and see if that gives you better readings?

No response, so will close for now.
