Hi reaper7

Thanks for this great library and the examples.

I am working with SDM 120C & SDM72D. With the SDM 120C requests can be done without any delay. When I try the same with SDM72D the energy meter reboots after 1 or 2 requests, so that the transmission of more than 1 measure in the read intervall does not work stable. I got it stabilized by putting a delay of 500 ms after the sdm.readVal request.

I am using the example "sdm_live_page_esp8266_hwserial.ino" with a swapped hwSerial on pins 13/15. I had made the same experiences with ESPeasy using the SDM plugin (testing)

Has anybody else made similar experiences or is something wrong with the energy meter SDM72D.
In my experimental setup I have just connected L1 and N to 230V. I have not tried it with 3 phases.

I want to bring ESPeasy to work with the SDM 72D and are willing to port the new SDM library to the ESPeasy framework.
So far it is still using the old SDM lib with the separate constants for the different energy meters.

Regards

Dirk
