I'm creating my own integration but it's still in a rough state. See here: https://github.com/bkintanar/home-assistant-mercury-co-nz. It has the hourly/daily/monthly usage graph for energy at the moment. Planning to add Gas and Broadband.

This is really great.
I loaded it onto my parents HA in place of the broken Opower.

I have noticed that it displays both Usage & Summary fine in Edge but Brings up a Configuration error in Firefox.
I am guessing this could be a setting in FF blocking something.

Apart from the above, it is really great and I highly recommend it.

Thanks

Thank you for testing it. I still need to implement the other mercury graphs as HA cards. The configuration error happens to all browsers at the moment. I’m new to home assistant integration, so I’m still figuring it out. But a workaround would be just to try to refresh the dashboard and it will load itself.

Very nice! I had to manually copy the main card and monthly summary js files to a new folder in /www/mercury-co.nz/ but after doing that and adding the matching dashboard resources config as below it came to life.

/hacsfiles/mercury-co-nz/custom-chart-card.js

/hacsfiles/mercury-co-nz/monthly-summary-card.js

Not sure why HACS didn't do it automatically, as it can't serve front-end files from the /custom_components/ folder as had done it for some other plugins I have.

Thank you for the info. I haven’t tested installation using HACS yet as I haven’t published it there. There are still a lot of work that I plan on doing. Not sure as well what the previous opower integration provided. I would love information from others on this and would like to implement them in this integration too just to cover what opower was providing before and possibly more. If anyone of you are keen, I’d be more than happy if anyone could help create github issues on what is needed to be added in the integration.

I only have access to energy, gas, and broadband, so I can only add those services. So mobile can’t be added since i dont have an account with mobile with Mercury.

Legend! Added to my HA and works as intended. Thanks!

Thank you for trying it out and for reporting that it's working for you.

Just an FYI as others said, I'm just the messenger but I did pass the feedback/comments on from the thread to the relevant people internally.

While I can't officially endorse it, just wanted to say great work bkintanar - Looks great.

Thank you! I hope I can give the support the community needs on this integration.
