So, when I installed, opkg also pulled down and installed all of the following. Are they all needed?

libpthread
librt
libusb-1.0
libusb-compat

The following are what I am installing in my image builder builds. It would be good to know which are needed and which are not. I'm assuming the above are definitely needed but there was no mention of 'already installed and up to date' for example on any of the following. Meaning, maybe I don't need those?

kmod-usb-core
kmod-usb2
kmod-ledtrig-usbdev
kmod-usb-ohci
kmod-usb-hid

So if I installed the right packages and now have a working build, I could copy usbtemp to my image builder builds and TEMPer would work?

I'd love to better understand why nothing seemed to work and yet it was actually compiling and it installed.

As an update, I've been playing with both the image builder and the buildroot and while I love the ease of image builder, I can see why/how buildroot will be better but the learning curve might be beyond me and the time I have available.

Using image builder, I added all of the packages needed but wasn't able to add the temper package because when the error comes up, it kills the build. What I've done (for now) is to copy the package into files/temp so that it's there once I fire up the device since I have no idea how to automatically make it part of the install.

In buildroot, I'm still trying to figure out why things don't work too good even though it seems I am adding the proper modules etc, then compiling.

By the way, if not mentioned in this thread. The reason the old TERMer wasn't being seen is that it is a USB 1.0 device and the tp-link I am using is a 2.0 device. I solved this by using a 2.0 hub between the tp-link and the usb device. Then the tp-link could see the device. I tested this on two different device types and it worked.

You definetely need libusb-compat. I tried without and it didn't even compile.
libusb-compact selects libusb-1.0, which selects librt + libpthread.

-> Yes, they are all needed for temper to work.

kmod-usb-core ->     Kernel support for USB. -> won't work without.
kmod-usb2 -> Kernel support for USB2 (EHCI) controllers -> unsure, if needed, since temper is an USB1 device, not an USB2 device. Try it without.
kmod-ledtrig-usbdev -> Kernel module to drive LEDs based on USB device presence/activity. -> certainly not needed in your case.
kmod-usb-ohci -> probably needed
kmod-usb-hid -> unsure if needed. Is temper actually a HID?

Yep!

Run lsmod to see what modules are running.  Modules built integral to the kernel may not appear in the installed kmod-xxx list.

Installing ohci or uhci (depending on your hardware, but you never need both) may allow a direct connection of a USB1 device.

You're using the wrong temper hardware with this version of the temper software.

thx

Any idea how to make him work on my OpenWRT ?

Sure.. just follow what I just went through and find the right source for your build.

Once the package is compiled, you can install it like any other package.

Then the next question would be...

Once I have installed my new build onto the device, I only need to run the installer to install the temper package once right? So basically, I just need to run something like 'opkg /temp/temper' in a one time way.

Is it a problem to have both? I don't mind using a hub, I have other things I'm wanting to connect and try out.

>Look here: https://github.com/petervojtek/usb-thermometer
>usb-thermometer: TEMPer1 and TEMPer1F

Anyone know if the project supports the external gadget and/or what it is?

http://www.ebay.com/itm/PCsensor-USB-di … 4ae05de057

Although vojteks version supports TEMPer1F, it doesn't seem to support TEMPer1F_1H.
Looking at https://github.com/petervojtek/usb-ther … pcsensor.c you'll recognize, that there's only temperature mentioned, no humidity.

Do you need the *external* humidity sensor? If you can live without that: See TEMPerHUM -> http://pcsensor.com/index.php?_a=produc … uct_id=178
Corresponding software: https://github.com/olegstepura/temper-hum-hid

Yes, I didn't see that either.

I don't *need* humidity, I'm just trying to learn by coming up with needs
I am somewhat interested in weather however so I'd love to interface to something which would give all the typical temp/moisture/pressure readings etc.

However, the trick for me is to find things which are dirt cheap. Not having a *need* means being interested if I can keep all of my curiosities cheap.

Yeah, finally my TEMPer devices arrived!

Downside: They are 0c45:7401 -> doesn't work with the given TEMPer version.

Hmpf... now I have to get some other TEMPer version running that supports 0c45:7401, which is not as easy as the version for 1130:660c...

Cooool, got it working with my 0c45:7401 :-D

I was thinking of picking up another one but I got sidetracked. I would like to find one that has more sensors, like temp, moisture, maybe barometric pressure, etc.

I doubt that you will find a cheap multi-sensor device. Humidity and pressure sensors can be quite costly... You see, already the TEMPerHUM costs a multiple of the TEMPer.

Not so small, not directly USB, but somewhat cheap available on ebay: Lacrosse WS2300.
Temp, Humidity, Pressure for roundabout 25,- Euro. Works with open2300, which is available in OpenWRT. Needs USB-> RS232 Adapter (FTDI or PL2303). Good value for money.

If you find a small multisensor USB device: Please let me know, I'm always interested in this topic!

When I looked back when we started this thread, the best I could find was around $60/$100 if I recall so yes, it would not be cost effective for playing around with but maybe for some other purpose.

My second TEMPer device arrived today: It's a TEMPERHUM1V1.2 (0c45:7402).
I managed to compile https://github.com/joeyloman/atmoslog, but the values I get back seem to be incorrect (e.g. I don't have 100% humidity here

Still some work to do, but almost halfway there!

For my datacollection, which hardware works with which software: Can you please post the output of the following commands?

lsusb
lsusb -v -d 1130: | head -n 20

Sorry, didn't get any notification. Are you wanting me to do the above?

Yes please!

hmmm...

root@OpenWrt:~# lsusb
-ash: lsusb: not found
root@OpenWrt:~# lsusb -v -d 1130: | head -n 20
-ash: lsusb: not found

I'm sure this is the build you sent me because I never install any service other than ssh.
