Hey guys,

thanks for this great and insightful thread and initial explanation / setup @pbrink

I own the following Meter: Maddalena DS TRP series (model number TCM 142/08-4604).

It actually lists an accessory called reed switch TRP (REED SWITCH TRP - PULSER), which means that it should have a magnet somewhere reporting a pulse, however I have not been able to read any pulses neither with a simple reed switch or the LJ18A3-8Z/BX proximity sensor. The simple reed switch and the sensor have worked on magnets / metallic surfaces, however it doesnt seem to work on the water meter.

Do you guys have any idea / hint? I mean worst case I can buy the official accessory, but since I had all the other items lying around I thought I would give it a try :slight_smile:

Thanks
Seb
