question

Brilliant, gathered together my temperatures, tanks and LPG cylinders into 3 useful graphs with single Y axis on each graph.

All we need now is for the custom widget to bring up the actual device names not the generic titles.

custom y-axis is soooo good!!

but its not possible on my Android Phone to set negative for y Values (for e.g. current) no "minus" available?!

also it would be great, if we can enter decimals/digits for the min/max values. Especially for Voltage it could be required to set a refined range.

and... at my trials, sometimes only min and max numbers are shown for the axis scale, nothing inbetween, see example:

I think that if you have several values of the same thing, i.e., W or V, you should have an option to 'unite to other W values' and show only one column of numbers, and be in the same scale as the other values.

I have made two graphs that are basically the same, only one is for when the numbers are high and other for when they are low. But as I have to use a 'hardcoded' limit, I cannot use only one graph. One has scales from -300 to 700, and the other from -800 to 1900.

Please autoscale and unite by default all values that are the same.

Than you for this Y-axis customization.

I tried simple, single custom Y-axis for AC-in 3 phase lines.

The graph looks good but not voltages I am getting from my grid. :)

My grid limits are 253V and 207V so it would be nice to be able to add those as additional red lines at those voltages, but this would be just "cherry on the top" :)

I wanted to create this widget because the standard had voltage range from 0 to 320V and was almost impossible to see if the AC voltage is "out of bounds".

After saving my widget I noticed that from time to time the standard graph for "AC input Voltage And Current" changes the Y-axis to 185V-280V.

When I reload the VRM page this graph goes back to Y-axis 0V-320V, but when I click on "phase 2" tab it shows Y-axis 185V-280V (same with "phase 3").

The funny part is when I press "Phase 1" tab it now has Y-axis 185V-280V.

I wonder why after creating my custom widget, the Y-axis on the standard graph changed.

That same Y-axis change happened to standard graph for "AC Output Voltage And Current" but this one changed permanently and VRM page reload does not bring it to the previous Y-axis 0V-320V. I am not attached to that Y-axis range (I like the new look) but this looks a bit inconsistent.

one more comment:

Would be nice, if values that use the same [unit], also use same digits&decimals?!

See right Y-axis in picture above.

Would look much nicer, if both show the same 200A and not 200.00A

When I try to create a custom widget and specify custom ranges for the y-axis I'm not able to set a value that has decimals in it.

Way to reproduce:

1. Create or edit custom widget
2. Select manually set one y-axis scale for all parameters
3. Edit eg. maximum y-axis value to 4.2
4. Click Save
5. "Enter a valid value" pops to the maximum value field.

If I try to set the value to 4,2 the custom graph can not be saved.

After some investigation I got it to accept the dot separated number. The trick is to inspect the maximum field with the browser and change the type of the field from number to text:

Chang this line

<input data-v-6625e43c="" type="number" class="sg-element">

to

<input data-v-6625e43c="" type="text" class="sg-element">

I think the root cause it the problem is that here where I live the decimal separator is ,(comma) instead of .(dot) which is used internationally.

I stumbled upon this knowing there was some work in progress and a lot of folks (me included) asking for it. This is a huge step in the right direction. I have two sets of battery strings, each with their own SmartShunt. Getting them to display both voltages or currents was impossible and looked horrible before this change; now:

I have a couple further enhancements that shouldn't be all that difficult but would add a tremendous amount of flexibility and power in these custom widgets:

1. The ability to assign custom ranges to each device is good but what would be better is to have the ability to group similar items (like voltage or current) and let them auto-range as a group the way they do now individually. For instance, in the graph above, there are only two items; one each from two different SmartShunts. They have identical custom ranges set so they properly display large voltage swings but when those are not present, the tiny voltage fluctuations are not visible due to the large voltage range. If there was an auto-range setting that allowed both voltage devices to be "linked" in a group and the group voltage used for auto-ranging, it would allow the tiny voltage fluctuations to be visible when the larger fluctuations were not visible:

It would also be nice to have a little more granular custom ranges; single volt increments are a little coarse for seeing tiny voltage fluctuations. The voltage granularity can currently be typed into the interface and seen in the sample (really cool BTW), but is not accepted by the interface when closing the window; it only appears to accept whole numbers.

2. Because the GX device isn't (currently) capable of combining SmartShunt metrics to generate a true "system" metric, it would be nice to add that functionality in the VRM. If custom widgets were capable of performing some mathematical functions on multiple and/or grouped devices, some of the missing functionality in the GX device could be done in the presentation of data that already exists. Examples would be to average SmartShunt voltage, add SmartShunt current, and take those results to generate a true or averaged system power (averaged SmartShunt voltage X added SmartShunt current = System SmartShunt Power or watts).

Thank you for the Custom Widget enhancement; it certainly makes it easier to generate graphs to compare device data. Looking forward to future enhancements.

I don't know if I missed this originally or if there have been some enhancements but... It appears some custom widgets now display a single range (like PV Voltage for instance). This makes displays look much nicer and dynamic based on what is being monitored. It appears at least in some cases, it is not necessary to specify a hard coded range to get the custom widget to display like this:

If this is a recent improvement, thank you...

Something else I noticed is the missing data for PV current.

I am not sure why because it (current) shows up in the PV voltage/current standard widget:

one other thing:

if you select "manually set one y-axis for all parameters"

there is some bad formating in my opinion:

all the curves are drawn until the very edge right/end of the window.

This makes it somehow hard to read.

On all other display types, like auto y-axis, or multiple y-axis, you always see some space/clearance on the right side of the window. It is much more pleasant to read curves this ways
