5. Don't work backwards by tweaking `prob_given_true:` and `prob_given_false:` to give the results and behaviors you want, use #4 to try and get probabilities as close to the 'truth' as you can, if your behavior is not as expected consider adding more sensors or see #7. 5.

6. If your Bayesian sensor ends up triggering `on` too easily, re-check that the probabilities set and estimated make sense, then consider increasing `probability_threshold:` and vice-versa. 6.
