I put the 2 ammeter clamps of the shelly in the main phase of the house, A and B, I have two solarflow with two hoymiles 800, hub1200 follows phase A, hub2000 follows phase B, I would simply like that when in the house I consume less than 800w hub1200 works, when I get more than 800 hub2000 starts on phase B, theoretically it should work in fact when for example I consume 1500watt hub 1200 comes out 800w at that moment hub2000 starts because it senses the difference of 700watt to make up for but it is not able to supply it does at most 20/30watt and does not push, I do not understand why
