Hi,

How many Energy Meter can Venus OS and the CPU on a Ekrano GX handle? I would need 7 devices connected via ethernet. Can I turn down the rate of data from the energy meter to save CPU?

A short description of my project: My family has 6 Objects with Electric Power connection. On 3 of them there is already solar power. I would now like to use an ESS with a big battery to deliver energy in the hours when the other PV Systems are not working. For that I have to monitor each individual Electric input or output and calculate the sum. With that sum I want to control my Multiplus 2 to deliver energy when its needed.
