Variable names issue?

Variable names issue?

@Vincent Raaijmakers

I’m trying to build a blueprint dashboard for visualizing the Dragino IO controller (LT-22222-L).
For some reason I encounter problems for all variables that have an underscore in the name.
In that case I do not see values in the widget and/or no icons.
Examples:
{
“variable”: “AVI2_V”,
“value”: “24.316”,
“serie”: “1632877925019”,
“unit”: “V”
},
{
“variable”: “DO1_status”,
“value”: “H”,
“serie”: “1632877925019”
}

Is this a known issue… or am I missing something?

Thanks!
Vincent
