Wall Mounting & Power

[wcndave]

There seems to be a lack of a power button on the Joggler.

I have spOS and if i press the power button then it just shuts screen down as any touch on screen wakes it up and carries out the action of where i randomly touched...

If I power down, then the only way to power up is to remove and re-insert the power supply?

This seems a bit odd, and also makes wall mounting difficult, as you won't have access to the power cable.

I was thinking about PoE, however I am not sure how that works with the power on limitations - can you restart the device by pulling the network cable at the other end?

sqpOS has a 'quit' option doesn't it which allows reboot or shutdown. Mind you, you'd have to still power it off via the plug to restart it.

Yes, if you shutdown there, or for some other reason (eg accidental shutdown) then you cannot boot up with wall mounted device.
I was wondering if there was a hardware hack that had been done, or if PoE was another option, or would it even work!

When I wall mounted mine I was lucky in that I can still access the power adapter. I did think of cutting the power cable and adding a push to break switch in line.

In theory if you did use PoE then yes disconnecting the cable at the other end should do the trick.

I made a quick and dirty modification to the file
/opt/squeezeplay/bin/sqp_JogglerPower.sh

To remove the power off command, it's still there in the quit menu but now does nothing when pressed. If I want to power off I simply type sudo poweroff at the command line (either Putty on my PC or usually in JuiceSSH on my Nexus 7)

This means I'm unlikely to accidentally power off

I actually would like to be able to power off, however there's no way to switch on is really the problem. The other option is to leave it on all the time, which I really don't like... but then accidental off is issue. However with PoE I could just remove and plug the network back in to power it up again.

Also your idea would help - thanks.

I just wish there was some way to power down as I really don't like leaving stuff on all the time.

[ilovemyjoggler]

Obviously you know what you want but they were built to be left on all the time weren't they? I think it's been reported on the forum that powering on & off has caused problems for others? But i could be wrong...

Its really weird, I have a Joggler in the kitchen that my dear wife switches off every day at the socket , with no ill effects it runs PNP , however another Joggler only needs a split second power cut to kill it completely and need a complete re flash to bring it back to life.

Personally; I just shut off the screens remotely and leave the Jogglers running at night. Historically I have done this automatically with motion sensors triggering the screens on and off or lately now just a timed remote shut off.

I do also have one managed 24 port midstream injector POE switch which I can shut off the power on the Jogglers if I need to; but do not.

[wcndave]

It could be 43kwh per annum and wearing out parts to leave it on

I might try putting a switch inline, however wall mounting would become interesting.

Just odd, never seen a device without a power switch before.

Has anybody done any tests to see what a 24/7 joggler would cost / energy condumption. @

The joggler was designed as an always on device to be left in say the kitchen to organise the familys life so hence the lack of power switch, it would have been handy though.

The screen can be set to off so that is not draining power

[wcndave]

I guess it was meant to be used like a tablet, but lacks the "instant on" feature, and therefore was left always on.

[pete]

That and it doesn't have a battery for the clock such that it needs to sync its time up from an NTP server or manually on bootup which is sort of a pita.

The power levels consumed are way less when the LCD backlight and LCD are in off mode. Best test is just touch the screen or case after a period of time when LCD is on or off.

Really messes with things with it boots up in the year 1500 or 1600 way before there were computers.

Although technically I would suggest a tablet doesn't turn off, it just goes in to standby under normal use and although not quite the same thing I consider using the power button in SqPOS that turns off the screen to be essentially a standby mode.

Yer, probably not too dissimilar. I guess i was thinking that a tablet when on last 9 hours, and when in "standby" has same battery after a week, therefore is consuming ~ 0. Whereas a running OS is a bit like my headless NAS, which even with disks powered down is a few watts.

I'll learn to live with it, just have to add some extra PV panels to my roof to ease the conscience
