I read that this board will not recharge the batteries without physical intervention, i.e. pressing the switch, after a power failure. this would make if fine unless you want unattended operation. On Sat, Aug 4, 2018 at 8:24 AM, David <david@kg5rdf.com> wrote:

Hi All:

This topic comes up from time-to-time!

Does anyone have experience with the following UPS HAT:

http://www.pimodulescart.com/shop/item.aspx?itemid=50

The ordering options seems to be a little confusing!

Additionally, what I am looking for is:

1. Does this fully restore power once the battery has been discharged and the AC power is restored? - i.e., no buttons to press (my application is in an unattended / remote location)

2. Is this the s/w that I need to install: https://github.com/modmypi/PiModules/wiki/UPS-PIco-Installation -> Any incompatibility / will it break a DIAL install?

Thanks,

Ramesh.

<-- Great! - that's very interesting.  Among the FAQ's for that product, someone does reference the need to push a button.  I have a RAVPower USB bank - and it works great - but once the battery has discharged, it needs a button to be pushed.  I use the Allstar PI as a jump box to tunnel through to other devices on the same network - hence my need for the device to auto-recover and gracefully shutdown to avoid corruption of the SD card. I've been thinking about a UPS as I could use that to keep other devices powered up during a power outage.  It would be awesome to have a UPS where the AC outputs can be switched remotely (i.e., to recycle an appliance / device).  My initial thought was to use an IP9258T power bar. I'm currently using one of these: https://www.amazon.com/Jinvoo-Protector-Outlet-Charging-Station/dp/B071ZGDDQ... The great thing about this is that it allows you to remotely control each output and the USB ports - the bad thing is that when there's a power outage, it seems to default to all outlets OFF and turns on the USB power..... DUH - since my RAVPower USB bank has been plugged into one of the AC outlets, the fact that the power bar defaults to OFF after a power outage, is forcing my USB battery bank to discharge over time.
