@michael Those are exactly my findings. I also have a piezo rain sensor and tipping rain sensor with the funnel upgrade and I feel they complement each other perfectly. Yes they work out much the same in the end but the piezo is much better at sensing the very fine rain which frequently occurs in this part of the world which the tipping sensor never registers.
