Shelly EM50 and Shelly PRO3M

Good evening, is it possible to view on M5STACK CORE2 the power detected by Shelly EM50 and SHELLY PRO3M via Modbus TCP?
Thank you all.

If you can write the code to read and display the information then maybe.

Thank you all.are those Shelly devices giving it out in Modbus format?

@robski Hi, if I understand correctly, yes.

@ajb2k3 Thanks, but I can't do it...

you can learn it!
Modbus TCP is nice but not very easy to use as you have to deal with "cryptic" IDs. Shelly devices are also support MQTT and HTTP(S). It may be more easy to get the required data by HTTP.
I know only the Gen1 devices but the Gen2 and Gen3 should work similar. All possible requests are well documented https://shelly-api-docs.shelly.cloud/
If you type in your browser http://<ip-address-of-your-shelly>/status you get a answer as a JSON file. This can be parsed very easy in UiFlow or Arduino to pick out the information you want. Once you have it in a variable you can display it, calculate with it or whatever you want.
