Hi Jargo,
I was able to get out usable readings using the method I mentioned above, think the code you need to use depends on the processor on the grove hat you bought. The one I had the MM32 which was the new version at the time hence why the method above worked. However I’m unsure if it has been changed again since. I did contact seeedstudio technical support but had no response from them.
If i am able to find the full code i used i will post it on here.
Sorry if this isnt much help to yourself.
Cheers
alex
