No more fresh batteries

Describe the solution you'd like

An interesting function would be the management of the stock of the different stacks of the network with a decrease each time we press PRESS of an entity when we change the stack.

This could be used to launch a callback when there are less than X stacks left.

Thanks for the current integration, which is already a fabulous piece of work.

This is something I've thought about a bit and has been discussed in the past.
This would be a long term improvement, I'll move it into the discussions area so not forgotten and hopefully we'll get some more feedback on what might be wanted on this.

Great, thank you very much

I had a similar thought to this when I stumbled across this integration. The proposed battery stock management idea is nice, I think that would be useful. My initial thought was a custom card to display the types number of deployed batteries in a single view and number of batteries consumed, based on replacement count.

Adding a way to track battery cost with the proposed battery stock management would be great too. I imagine attaching a cost field to a "restocking" function would be a practical way to go about that given costs will vary wildly.

I think it would need a whole new dashboard rather than a custom card. Something I'm looking into but it's a very different skillset to create those compared with integrations.
I'm thinking something a bit like HACS experimental mode, a device list on steroids with action menu's and maybe mixing in a bit of something similar to the energy dashboard with multiple cards.
This isn't forgotten and I think the main integration will be settling down a bit so I'll get chance to explore this more.
