Using HWiNFO with Rainmeter

Post by **jsmorley** » March 16th, 2021, 12:20 pm

Important!

As of version 7.0 of the HWiNFO hardware sensor monitoring tool, the software has changed to require purchasing a yearly "Pro" license in order to use the Shared Memory feature of the software that allowed it to interact with the HWiNFO plugin for Rainmeter. This would make distributing Rainmeter skins to end-users problematic at best.

Martin Malik, the author of HWiNFO, has graciously worked with us to find a solution that will allow the software to be used for personal, non-commercial use in Rainmeter without having to purchase a license, while keeping his ability to monetize his application when used by commercial entities.

The approach consists of tweaking a feature of HWiNFO that was implemented years ago to support using the software with the now long-dead Windows Sidebar gadgets. This allows you to output the current values of one or more sensors to the Windows Registry, where it can be easily accessed using the Registry measure in Rainmeter. A distinct HWiNFO plugin for Rainmeter is no longer required.

All skins that use HWiNFO will need to be changed. While the new approach is actually easier to configure for the end-user of your skins, it is significantly different, and requires that skins be adapted to work.

This thread can be used to discuss this change, and help folks who need to revise their skins to adapt to this new approach.

This requires that you get the latest 7.02 or later version of HWiNFO

Just remember that it was version 7.0 that broke things, and it requires 7.02 or later to fix them.

Then carefully read and follow this guide

One initial tip I would give on this is that you should probably encourage your end-users to "export" all the sensor elements from HWiNFO that they are ever likely to need in your skin, and other skins they may create or try later. The issue is that the "index" numbers that are created will change if they later add or remove sensor elements from what they "export", and that can cause all their skins to need changes to the index numbers they use.

I exported a lot of CPU stuff, like the core speeds and temperatures, some motherboard temperatures, various fan speeds, hard drives temperatures and S.M.A.R.T. stuff, and a bunch of GPU sensor elements for my graphics card. I think I ended up with 40 exported (out of the HUNDREDS in HWiNFO) although currently I only use about 8 of them.

So I ended up with:

reg query HKEY_CURRENT_USER\SOFTWARE\HWiNFO64\VSB

Keep in mind that every computer this is used on will have different sensors that HWiNFO monitors. While there are very common sensors that pretty much any computer will have, even those may have completely different element "labels" depending on the hardware.

For authors of existing skins that use HWiNFO, I can often the following advice in order to move forward:

The goal should be to rewrite your skins to use the new approach, and get that out to your end-users as soon as possible. This might take some time however, and you will need to react to "whaaaa, it's broken!" comments that you get in the meantime.

1) An end user can just stay on any earlier 6.x version of HWiNFO, and the skins will just continue to work with the HWiNFO plugin for Rainmeter. That will buy them some time, but I caution that earlier versions of HWiNFO will quickly get out of date with the latest hardware. That should NOT be the recommended or suggested long term solution.

2) An end user can in fact use HWiNFO 7.x with existing skins and the HWiNFO plugin for Rainmeter, but unless they purchase a "Pro" version of the software, they will have to go into the HWiNFO "settings" and enable Shared Memory Support every 12 hours. This can't possibly be a popular or practical solution for the long term, but might tide them over while you revise your skins.

This is a great solution that Martin has come up with, and it appears to work really well.

The only catch is that this new scheme is so different that it is almost like a whole new third-party monitoring utility; i.e., no existing HWiNFO code can be salvaged.

Not complaining, mind you, it's just that this is not gonna be a quick conversion. I'm hoping I won't need to create HWiNFO 7.x-specific skins, or worse yet AMD/Intel/nVidia-specific skins.

P.S.: And thanks for jumping on this so quickly and creating a tutorial, that is super-helpful.

Certainly no "measures" created that used the Rainmeter plugin can be salvaged.

A measure that used to look like this:

Code: Select all

[MeasureCPUTempCurrentValue]
Measure=Plugin
Plugin=HWiNFO
HWiNFOSensorId=0xf0000501
HWiNFOSensorInstance=0x0
HWiNFOEntryId=0x1000000
HWiNFOType=CurrentValue

Will need to look like this:

Code: Select all

[Variables]
CPUTempIndex=10

[MeasureCPUTempCurrentValue]
Measure=Registry
RegHKey=HKEY_CURRENT_USER
RegKey=SOFTWARE\HWiNFO64\VSB
RegValue=ValueRaw#CPUTempIndex#

I don't really see any issues with different hardware vendors that didn't already exist with the plugin. So for instance, Intel CPU's have a temperature value for each separate core, while AMD has only a single temperature value for the whole CPU.

This doesn't eliminate the "hassle" for end-users to configure things for your skin(s), but I would argue that while different, it's actually easier.

So instead of having to use the separate Shared Memory Viewer application to find and copy / paste the following values into a .inc or the skin:

Code: Select all

HWiNFOSensorId=0xf0000501
HWiNFOSensorInstance=0x0
HWiNFOEntryId=0x1000000
HWiNFOType=CurrentValue

They need to do some up-front "configuring" in HWiNFO, and then just get the single "index" number that can be found with:

reg query HKEY_CURRENT_USER\SOFTWARE\HWiNFO64\VSB

Or you can give them this skin and activate it on demand...

Code: Select all

[Rainmeter]
Update=1000
DynamicWindowSize=1
AccurateText=1
OnRefreshAction=[!CommandMeasure MeasureReg "Run"]

[Variables]
ScrollY=-10

[MeasureReg]
Measure=Plugin
Plugin=RunCommand
Program=reg
Parameter=query HKEY_CURRENT_USER\SOFTWARE\HWiNFO64\VSB
State=Hide
OutputType=ANSI
RegExpsubstitute=1
Substitute="ø":"°","    Color.*\n":""

[MeterContainerBack]
Meter=Image
W=600
H=300
SolidColor=47,47,47,255
DynamicVariables=1
MouseScrollDownAction=[!SetVariable ScrollY "(Clamp(#ScrollY#-20, (-([MeterReg:H]-310)), -10))"][!Update]
MouseScrollUpAction=[!SetVariable ScrollY "(Clamp(#ScrollY#+20, -310, -10))"][!Update]

[MeterContainer]
Meter=Image
W=600
H=300
SolidColor=47,47,47,255

[MeterReg]
Meter=String
MeasureName=MeasureReg
X=5r
Y=#ScrollY#
FontFace=Segoe UI
FontSize=11
FontWeight=400
FontColor=255,255,255,255
AntiAlias=1
DynamicVariables=1
Container=MeterContainer

That will provide a scrollable list of all the sensor elements they "output" in HWiNFO, with the required "index" numbers.

I just can't stress enough that those "index" numbers need to be done as [Variables] in your skin, either directly or in a .inc file. As the end-user gets and runs more skins that use HWiNFO, they may need to add sensor elements to what they "output" in HWiNFO, and when they do, those index number can change. You need to make it as easy as possible for them to change the index number values.

Yes, actually that's the bit I'm currently struggling with. With the plugin, if the end-user didn't have a sensor, the skin could use a default Entry ID of 0x0, which will enable the measure to still function and will always return zero (or use those -9xxx codes if preferred). This would then be ignored and/or otherwise dealt with as needed. In other words, skin author could create conditions that could react to a zero value to take some action to adjust skin logic.

But now how to handle a sensor that doesn't exist? Using your example, RegValue=ValueRaw#CPUTempIndex#, what if the user had no sensor for this? Do we default the CPUTempIndex variable to zero? That might return a non-zero result (i.e., the value of something else).

Any thoughts or suggestions?

If you use an Index value that does not exist, it will just happily return both number and string values of 0/"0". You can certainly react to that. If they use Index "10" to mean "temperature" and it actually means something else, like "fan speed", I don't see how you deal with that for them.

It's the Registry measure itself that gracefully deals with it when you ask for registry values that don't exist.

If they use Index "10" to mean "temperature" and it actually means something else, like "fan speed", I don't see how you deal with that for them.

Oh yes yes yes.... I forgot that Registry measures return nothing for invalid keys. So you could use any index for "missing sensors", like -1 or "x" or whatever.

For the specific issue with the number of temperature elements that vary with Intel vs. AMD, I guess you might want to have two different .inc files. one that has indexes for all 8 or 16 or whatever core temperatures on Intel, and one that has the single index for AMD.
