Two weeks ago, I picked up my brand new Growatt Aura 5000 Battery system. As this is a plug-in system, it all started out simple, until I had to connect e meter. There are several meters mentioned in the manual and I chose the Chargee Sparky P1 meter.
Connecting it was a hassle. Although I had both devices on the same 2.4 Ghz network and both within 2 meters from the AP, the connection was not going to happen. After 2 days of frustrated trial and error it magically worked.
The smart mode of the Aura selected but during a positive load, the Aura began to flutter from +400 to - 400W due to the Sparky, which could not send info quick enough. So I decided to let HA come in and save the day!
Growatt has made a real fortress of the Aura. Grott will not work because you cannot reroute the ip adress and port of the datalogger or the info that is sent is not picked up by Grott. Direct access to the Modbus RTU port is prohibited. It can be activated with register 30100 but that resets itself.
The officiat Growatt server intergration does not work with the Aura yet and does not provide Soc or any other useful data to work with.
Modbus TCP is not available according to Growatt service. Ther should be a project from Noah that could work around this but it will not install in HA because there is an error in the code.
Is there anyone who can solve this problem?
