Hi, RazorCopter

I think this line is not correct:

    `json_body={"Time":actual_time,"ENERGY":{"Temp":(msg.temperature),"H_Total":(msg.h_total),"E_Today":(msg.e_today),"E_Total":(msg.e_total),"VPV1":(msg.v_pv(1)),"$`

it ends with a $ but i guess it needs to be:

json_body={"Time":actual_time,"ENERGY":{"Temp":(msg.temperature),"H_Total":(msg.h_total),"E_Today":(msg.e_today),"E_Total":(msg.e_total),"VPV1":(msg.v_pv(1))}}

THis worked for me. But is it also possible to have E-Instant / Real-time information?

RazorCopter commented 5 years ago

sorry, copy / paste error! :) https://pastebin.com/qD51X299 It is not possible to have data in real time because it is not possible to interrogate the inverter but only to listen.
