Getting started, easy information before the order

Hi all,
I want to install my Solar PV (adding some CT sensor inputs) + temperature and umidity sensor (+ in future, heatpump control)

My question is, maybe, very stupid.
I have the solar inverter in the third floor of my building, the Main utility meter in the first floor that after will split in two apartments (2nd and 3rd floor)

if I have an Empi Solar PV + EmonTx.
Am I free to use every sensor like I want or the Empi Solar PV has to be connected only for Grid-tie inverter and Main utility meter?

Thanks in advance for your time

Hello @Mirko_Orazietti and welcome! yes you are free to connect up as many sensors as you want, and configure it to do multiple different things.
