Hello MightyPirates-crew,
I might run in a issue and I need approval. I set up to to try out the OC-API a simple setup to read from Inventories and Tanks:

For each task I used the appropriate module (eg. Tank I use the _"Tank Controller Upgrade"_). The Inventory Controller Upgrade worked fine, but I run into some issue with the Tank one. The program returns, what ever what side (4 or north in this case) or method I use nil or {n, 0}.
I used both versions the recommend version on curse and the dev version on http://ci.cil.li/job/OpenComputers-dev-MC1.10/. (which fixed the transformer bug)
I need now approval for my bug! Thank you for your help and time,

I can confirm that. Neither the tank controller upgrade nor the translocator seems to be able to read tanks in 1.6.0.3 for MC 1.10.2.
@Belgabor , thank you.
Now that this is confirmed and I'm not totally bad in lua (hehe) I hope for a fix soon.
Not quite the same issue, but I have a similar problem with Ender IO Capacitors. I cannot seem to read from those. Could this be happening due to an outdated API?
@mzx987 That is not related at all.
I cannot reproduce the issue on OpenComputers 1.6.0. Could you test using the latest release?
My setup:

Code working as expected:

I tested this with several mods using OpenComputers-MC1.10.2-1.6.0.4
I will list the mod and version along with a link to my testing setups:
TConstruct-1.10.2-2.5.6b Gallery
Mekanism-1.10.2-9.2.0.294 Gallery
deepresonance-1.10-1.3.0 Gallery
extrautils2-1.10.2-1.0.0 Gallery
EnderIO-1.10.2-3.0.1.135_beta Gallery
For the blocks that can be configured I did try most of the configurations and I tried all of the sides of the blocks pictured above.
And here is my computer setup

In my testing I found that the thinkers smeltery drain worked in 1.7.10 with OpenComputers-MC1.7.10-1.6.0.9-universal
but 1.9 and onward it stopped working
Here is the Client-2 log http://pastebin.com/hpyEmd4A

I hope this helps.
Would you mind testing if it works for you with IC2 experimental blocks?
I was only able to test with EnderIO, but https://github.com/Vexatos/OpenComputers/commit/533648909b9a9b5fbc8d075e96c7d79b0ac99af2 adds support to that at least (IFluidHandler capabilities in general). Would you mind testing all those mods using this build[URL removed]? It contains the aforementioned addition to OC.
I have confirmed using OpenComputers-MC1.10.2-1.6.0-dev+5336489 that the mods I listed before have started working with the transposer as expected. The industrialcraft-2-2.6.96-ex110 blocks worked before this version using OpenComputers-MC1.10.2-1.6.0.4 and still function normally after.
Thank you very much, so it was, indeed, just a missing feature, basically.
