FoxESS (US) mqtt and sdk

Sharing it with the community here:

FoxESS Add-On for HAOS: GitHub - HarshBhardwaj/foxess-add-on: Runs the local FoxESS Smart WiLAN → MQTT bridge directly on your Home Assistant machine. It reads your inverter over the LAN (no FoxCloud) and publishes ~21 sensors via MQTT Discovery, so a FoxESS device appears automatically in Home Assistant. Broker credentials are pulled from the Home Assistant MQTT service — you don’t configure them here. · GitHub
FoxESS SDK: GitHub - HarshBhardwaj/foxess-local: A fully-local, evidence-first Python SDK for FoxESS “Smart WiLAN” devices (e.g. Fox Hub G2 gateway + AIO-H1 inverter). No FoxCloud, no account, no internet — it talks to the device’s own http:///api/v1/sunspec/data endpoint and decodes the SunSpec/Modbus frames locally. · GitHub

Hopefully, this might help others in the community.

Suggestion:
Add-ons have been renamed to Apps about a year ago now.
Using the term Add-on with new software can cause some confusion because people have been trying to find add-on in the HA UI, and it is no longer there.
Please consider a wording revision.

A simpler approach may be to use the Create a link – My Home Assistant facility…

For instance, this install sequence from your readme don’t work:

Click the button above (or Settings → Add-ons → Add-on Store → ⋮ →

Testing the actual install instructions that you copied from elsewhere is a good best practice to follow. So is this: AI Policy | Home Assistant Developer Docs

Thank you very much for reviewing my mistake and guiding me. This was my first time using this application or building it out but I’m glad there are people out here who are willing to guide new comers. Appreciate it!

I have corrected my mistake and made sure the fix is working.
