Hi,
Many smart meters can be read out using their optical port using https://www.ebay.de/itm/313884760667 and https://tasmota.github.io/docs/Smart-Meter-Interface/ for example.
My smart meter, an edmi es-10a also has an optical port, but it is not on the tasmota list, nor have I found any blog/forum post discussing this smart meter. Has anyone tried reading out the edmi es-10a using the optical port? Is this possible?
Thanks!
