Gadget Review: SMT1500i UPS + Linux Instructions

I never get power cuts. But, we've had two in the last week. They've both been fixed quickly, but it takes an age for my cable modem to reboot - and then an age for my smarthome to reconnect to the WiFi. So it was time to invest in an Uninterruptible Power Supply (UPS).

Gadget Review: SMT1500i UPS + Linux Instructions

They've both been fixed quickly, but it takes an age for my cable modem to reboot - and then an age for my smarthome to reconnect to the WiFi.

@Edent I’ve had good luck using https://www.battery-direct.com. That said, I’ve also added some test power banks to the mix and they are a game changer.

I’m testing in series with socket->power bank->UPS. Even if it takes the bank a couple of seconds to failover, the UPS handles that nicely. On a W/$ basis the power banks go a *lot* further so you’re looking at hours of uptime, not minutes.

Bonus: schedule charging in off-peak hours & draw down on peak for savings on power bill
