Could this project be done single handed by a ESP32-Wroom dev. board?

Hi
If for some reason the readout of MEP data fails, the MEP indicator in the web interface turns red and also the text "MEP: No data from Smartmeter for the last 30 seconds" appears in the header part of the webinterface and stays there forever (probably until a restart of the ESP happens), although data is readout perfectly as can be seen in the webinterface.
Hi there,
First, thank you for this great project! It has been incredibly useful.
I would like to request an enhancement to the sampling interval. Currently, the data is fetched every 2 seconds, but I believe it would be more beneficial if the sampling could be done every 1 second instead. This change would provide more granular data, which is essential for my use case.
Thank you for considering this request. Keep up the excellent work!
Best regards, Hochi
Hi Bert
I added my NES smartreader to homeasssistant using MQTT. Subscribing to all topics (#) I get 35 different values displayed in the homeassistant dash board. This works ok, but the field "AMS reader Accumulated reactive export" shows strange values: First of all I do not export power and second the value floats between positive and negative, small and very lage numbers. To me it looks, as if the field was not properly initialzed in the SW or that the NES meter delivers wrong or uninitialzed values.
Could you please have a look at this?
Thanks, Hanspeter
