@BearWithBeard Thank you for sharing this great tip! - It works great and maybe finally I get my lightning detector working! Thanks @mfalkvidd For putting this in with the docs where it will hopefully help others. We need more examples like this in a knowledge base to save time reading through lots of posts that are many years old.

@APL2017 I agree, a 'current best practice' page with the latest recommendations would save weeks searching the forum looking for the hidden gem.

@BearWithBeard Thank you! I am really embarrassed with my, let's say, luck of understanding. But you made it clear again. Everything works as required!

@apl2017 most MySensors nodes are battery-powered and sleep to conserve power, which means they aren't "on". With that said, most examples transmit on regular intervals. The interval is configurable, so you can set it to a short interval if you are not concerned with battery consumption.

@tbowmo Thank you, supercap idea works fine, my first experience with supercaps.

@apl2017 on the öast message, the node is not getting ack from the next node. The mose common cause is i sufficiently clean power supply. What size of capacitor are you using? How is the radio getting its power? Adding wait(200) before the send call can help the power to stabilize. Since all communication before works, wiring and everything else should be ok.
