Hi!
I'm trying to use a mix of Arduino Nano + SIM800L + RTC DS3231 + 2x PZEM-004T to achieve the goal of upload the two Energy readings every 24h to Thingspeak channel. My sketch is this https://pastebin.com/a6Zn8HaV, i'm in doubt if the use of String class for the GET job is correct.
Could you help me?
Thanks

I've seen a decent number of tutorials for interfacing sim800L with HTTP, and specifically ThingSpeak. I'm sorry that wo don't have SIM800L a tutorial in our doc, but Ill bet you can find an external one that should put you in the right direction. And I happen to think ThingSpeak is a great place for Energy monitoring .
