Incorrect decoding for MIN 3600TL-X inverter?

[martijntonies]

Hello Johan,

I've installed the homeassistant-grott add-on with MQTT etc. But it seems the record decoding is somewhat off.

Here are values I'm receiving, the ones in bold are puzzling me. Let me know if I can help.

Can you run it with invtype=min in the grott.ini [generic] section?

If this not works please sent me the original Growatt data (with the /x) from the grott log?

Hi,

Entered "min" in the configuration for invtype and turned verbose mode ON.

Here's the results:

Which version of Grott do you use (Master or Beta?) The master branch does not have the min layout at this moment.

This addon is based on the 2.7.8 grott code and current grott_ha extension.

WARNING! THIS IS AN EDGE VERSION! ---8<---

I've checked your beta 2.8 branch, but have no idea how to install it, compared to the add-on by @egguy. I run HomeAssistant as a stand-alone machine without command line access.

Hi, I'm currently updating how the addon are packaged and named.

The future repository is: https://github.com/egguy/ha-addons the addon are published and updated automatically now.

The grott-beta in this repository is the 2.8 branch.

I will probably update the old repo in the coming days to the current repository and push grott and grott-beta and, remove grott-edge. I will continue to maintain the add-on in the old repository (https://github.com/egguy/grott-home-assistant-add-on/issues), but will most likely put a deprecation warning.

Thank you for that. Running this add-on now, with inverter type to "min". Things have improved!

These values now are equal to the Growatt Dash.

PV1 and PV2 today/total now both list values instead of only PV1 (although it seems the value has switch from PV1 to PV2)

PV Power Out now populated as well.

This seems wrong though, given it's just max word value ;)

Thank you both for your work.
