Very informative, thank you for sharing. That is exactly what happened to my Monport 60w.

If my sensors are 300mA current output (not workin anymore) but I only found sensors with 150mA current output (all characteristics are same just that one is a bit sif) is there a big problem or it doesnt matter at all and can work properly?
