I have a Neuron running a Mervis program for almost 2 years, together with a web-hmi page.
It worked flawless all the time, but today I wanted to add a variable to the webinterface and after that the webinterface dropped dead.
I already removed the variable and restarted the neuron a few times, but nothing helps to revive the webpage. All variables have a red dot and values.cgi keeps responding:
{
"ver": 1.0,
"code": "error",
"msg": "No variables from request available. Check device parameters and availability."
}

Why isn't the Analog Meter not useable in HTML HMI ?

Nobody who knows how to resolve this matter?

It doesn't seem to be possible to get any value in the HMI Web. I always get no values and the values.cgi responds with {"ver":1.0,"code":"error","msg":"No variables from request available. Check device parameters and availability."}

Looks like Mervis isn't very useable after all and things have moved to node-Red.

will go there too.

I tried several components in my HTML HMI view but the variables don't show values and have a red dot above them.

I tried to use normal Global variables, modbus values and a lot more but it is very strange how this all functions.
I also don't understand why certain variables are only useable on text HMI parts and others only on the graphical HMI.
