@pierrot10 Hi pierrot10 thank you for letting me know how it is working. I am glad to be of some help. I have no experience of using the water sensors, I only looked at the data you posted and made a mock up of the converter module for testing. My gardening is limited to two small potted plants that live on a window sill and have a capacitance sensor in each pot. Best Regards

Testing and updating can resume now my first year at university has finished and I now have 4 months worth of MySensors development to get started on!

oki. i'll improve this when i'll get a bit more time, that's quick to do. I've assembled smd version only so far. thx for feedback
