I have my 1W-net power injector plugged into the same UPS that powers
the PC running OWFS. I'm using a modified 1500VA UPS which I replaced
the stock batteries with 2 external heavy duty, deep cycle Optima marine
batteries. It provides battery backup for aprox 6.5+ hrs to the PC,
1W-net (powered by an old PC power supply), TCP/IP router, cable modem,
NAS, etc.
I decided it was just easier to power the whole network, rather than
individual devices since I needed the PC running OWFS to be up to take
the readings any way. I also use NUT running on the PC to monitor the
utility powerline and send me emails/text messages when a power outage
occurs so that I can check on the aquarium if needed.
It may not be the cheapest solution, and I probably have an over-sized
UPS, but it's pretty simple and this way it will still monitor tank
temps, etc and take action upon them during the power outage.

Hi List,
I was wondering if anyone has provided a battery backup for the 1wire
power.
As I expand and use more of the BAE910 intelligent slaves it becomes a
good option to keep these devices powered during power outages.
I have two USB adapters one has a hub installed and the other has
sensors directly connected.
HUB I know the hub has an onboard power connection and voltage
regulator inside so I suppose this should be easy, however really
wanted to somehow just use a battery pack and some diodes.
Direct connect to USB ...This maybe a little more interesting as I
currently use the USB power for the network
I was probably hoping to keep it real simply and use a couple of high
quality AA batteries in a battery pack to provide say 4.5VDC. I know
my problem will be the ADC within he BAE910 as I assume it references
the supply.
Has anybody got a simple battery backup on their network to keep the
sensors alive ?
