Some systems already have that. Replaced a switch yesterday and re-arranged some things on my network board and got a HomeKit notification that some things were offline and when it came back. Knowing when something goes offline isn’t as useful as keeping things up though. With something like a hardwired camera/NVR, even if your ISP service is interrupted the cameras can still record, and you can put a UPS there to keep things going, even if the rest of the network is down.

I heard there was a process for requesting additional data, but you have to actually pay for the 5 users and they’ll bump it a few TB every couple months on request. That’s from people reporting their experience with support, so it might not be totally consistent.

I kind of get it though, people hear “unlimited storage” and then don’t even make an effort to be efficient with that space, and just want to keep everything forever. There’s a real cost to that storage, and it’s higher than many think since it’s not just a single HDD like many would have sitting on their desk but a series of arrays/pools and all the related systems to ensure reliability and uptime. They probably did some calculation where 99% of users would be profitable even with their “unlimited storage” and eating it on the other 1% was a reasonable advertising cost. Over time that calculation changed and they had to update the service.

Presumably it was GSuite/Google Workspace. While they advertised unlimited storage if you paid for 5 accounts, it wasn’t really enforced so you could pay something like $20/month and get unlimited storage on G-drive. There was a daily cap on how much data can be moved, but that’s fine for hosting incremental backups like many that took advantage.

This is true in central Canada too. Heat pumps get pushed saying they put out 3 times as much heat as the energy they use, but electricity is 7x the cost of natural gas.

Even better would be if more devices used the lithium ion cylindrical cells. Higher power and energy density, while also being a standardized form factor that can be switched out as needed.

This is entirely regional though. The further you are from the equator, the more seasonal variation there is in sunlight levels, and heating/cooling loads. Around here our solar production is minimized during the season when our energy needs are maximized. We also don’t have variable rate billing, though we only get partial credit for excess generation, so battery storage will never pay for itself until something changes.

My utility gives a 50% credit on excess generation. Thing there is the utility is still the one taking responsibility for having the capacity and scalability to respond to variation in demand and production. When I was getting quotes, adding storage would have doubled the cost of the system for a day or two worth of storage. Probably would cost double again to have a system that would keep up through the winter.
