shouldnt this part:

local info = {
['EnergyStored'] = format_thousand(energy),
['EnergyCapacity'] = format_thousand(maxene),
['FluidName'] = fluidName,
['FluidAmount'] = fluidAmount,
['FluidCapacity'] = fluidCapacity
}
local msg = textutils.serialize(info)
rednet.send(15, info)

be this?:

local info = {
['EnergyStored'] = format_thousand(energy),
['EnergyCapacity'] = format_thousand(maxene),
['FluidName'] = fluidName,
['FluidAmount'] = fluidAmount,
['FluidCapacity'] = fluidCapacity
}
local msg = textutils.serialize(info)
rednet.send(15, msg)

because now you are just sending over your table (with the rednet.send(15, info) and not the serialized msg

Thanks for the feedback, adjusted a few things (forgot about the table API)
Need to clean up the code a little bit more (removing the comment parts that are not needed anymore)

Awesome, need it for a project i am working on with tinkers construct.
So this mod is a life saver

I am working on a automated smeltery from tinkers construct (Smelting armor, horse armor and such)
I want to use my pocket computer to check how much is in the smeltery (So i can activate the draining)
But i got stuck on a certain part...
The draining works perfect when i send a rednet command
But as soon as i send a rednet command for the amount of liquids (Mostly iron/gold is in it)
I only receive 1 message with the gold (at least it did, i did something and its broken again)
Using this in combination with OpenCCsensors (1.7.5)

Fixed it
Code i use on the pc:
http://pastebin.com/pvpeNXWA
Code i use on the pocketpc:
http://pastebin.com/yBdk2PUm

added freezing pocketpc after drain command
made a "list" of the materials in the smeltery

Not the best code, but hey it works for me

Thanks for this peripheral.
Only 1 small question, does it work on the newest computercraft?
