Hi KrisG,
I’m having the same issue. I have ver 1.0.23 and server B is showing Not Connected. I setup a SBC (AtomcPi) to listen to the port using the linux NC and nothing is received. I used NMAP from another PC to test the port and it did work, so NC was expecting the signal but the inverter wasn’t sending anything. 
I’m very interested on being able to store the data locally. Any advice, please share…
Thanx,
Ricardo
