I like that we can see our energy usage right from my email notification list of all actions taken in Power BI Desktop (which is very helpful).
It would be nice to have more filters for viewing/searching power bi reports so you don't need multiple tabs open or lots og time searching through different dashboards just trying find out what was done last week vs 2 weeks ago etc.. The main thing i dislike about greenily now its not free anymore but thats because they are growing their business which makes sense as there should always only everbe one tool doing this kind fo work! If anyones looking at using something similar then make sure u know how much data ur going into each month / year otherwise if things start getting big with regards numbers dont expect good support when issues arise - especially around billing changes!! We use them mainly within small companies where people do little analysis themselves however sometimes some larger clients will send us an issue report via text message asking.
