Hi all,

Another request for help from anyone with a Sontex meter.

I have an EmonPi2 installed now and mostly set up, but I still can&#;t get an output from the sontex 749. It doesn&#;t have an m-bus so that is not an option, leaving me with a pulse output and an optical output. I brought an optical sensor as part of the EmonPi2 package. I have tested it with a torch and it&#;s counting correctly, but it will not pick up any signal from what I think it the optical output on the front (the little LED in the centre). I don&#;t think the Sontex 749 is flashing. . I spent a good deal of last night in the dark watching the meter reading change as it counts up the cumulative kWh, but could see no flash. I&#;m thinking it&#;s either not activated, not functioning or infrared. I have been through all the menus to see if there is an on/off activation but can see nothing.

If you are looking for more details, kindly visit Plastic Roll Bags.

I thne attempted to repalce the optical pulse counter with a hard wired output from the meter. There is a &#;communication&#; symbol that appears to flash on the main LCD screen every 0.1kWh, so it looks like there is a pulse output. But I simply couldn&#;t get any count on the EmonPi2. I tried various wiring combinations of output 1, ground and output 2, but I&#;m not sure what I&#;m doing and really don&#;t want to damage the EmonPi2 either.

Has anyone managed to get an output from a non m-bus sontex meter? I&#;m almost at the point where I give up and replace it.
