Hi, I’m new here and after 1 year experimenting with Homey Cloud, I now changed to a Homey Pro.

The energy tab is now showing my Growatt inverter by reading cloud data, with quite a delay.  
I’ve read and saw a manual how to install a Modbus to have a local wired connection.

_Is it possible to setup a local - wifi connection with Homey Pro receiving data from my Growatt inverter?_  
(My Growatt has a std. wifi Dongle)

Thanks, Ruud

Hi Ruud,

When your Growatt inverter doesn’t have modbus onboard, it’s possible to make it work by adding a modbus interface. Here’s how Danee did it:

> [@\[APP\]\[Pro\] SolarEdge + Growatt TCP modbus](https://community.homey.app/t/app-pro-solaredge-growatt-tcp-modbus/45487/1579):

I connected both my Growatt 3000TL3-S inverters to the module and after some fiddling on the Inverters (Giving each a unique ID) and in the module’s settings I got it working! Here the settings that work for me: I made the following changes that differ with de module’s default settings: Network Settings Device Port, set it to 502 IP Mode, switched it …

Thank you Peter for pointing me to this description of a working solution that I may end up with inplementing as wel.

Does this mean that wireless solution (via the dongle) is not possible at all?

Yes, connecting to the inverter over wifi isn’t possible, you’ll have to take the modbus route.
