Is there any limitation of parameter entries in place? On the first look scrolling through the ESP8266 repo I didn't find any. I added arround 30 additional to Zombie VCU and it got realy laggy .

The main limits are based on how the web interfaces populate, as it is all dynamically driven. This requires pushing alot of information each time it updates or connects.

So ESP32 CAN Interface should solve the problem, right?

No thats literally the same, force all param info down a communication pipe line. When requesting spot values it will pull the same info as the esp8266.

The CAN is different as it only downloads the parameter descriptions once then only polls the values. That said over wifi always the full json blob is transferred but that's usually not the bottleneck

I added all this parameters. I know, it is a lot of characters I could save. I would realy like to have the categories also for values

.

The strange thing is, is that it is not just slow or not working at all. Some times after reset I am able to see all parameters and then get the red connection error. Sometimes it just don't load at all. This unstable undetermined behaviuor is weired and no good sign for a computer system.

With CAN interface it runs smooth.
