A long time ago lived in an apartment and used an openwrt router and some can-tenas to connect to the leasing offices guest wifi. Worked okay for about a year. Made sure to limit my torrents to after business hours. Then i was able to buy my own service so retired the setup.

That’s neat. I’m curious about what all the phones are running?

The private space sounds interesting. I wonder how it works in practice. Can any app be stored there?

exactly, i use https://iotawatt.com/ to monitor at the breaker box. Integration works well with HA

I have the circuits for all my “dumb” appliances monitored by my homeassistant. Then HA sends notifications to my phone. And it doesn’t need to send 3.6GB to the internet to do it.
