Did you add the declare statement for the virtual parameter in your default or inform provision script? ---

It does not show the VirtualParameters.ipa declaration statement. Here is a snip of my own: declare(“Device.ManagementServer.PeriodicInformEnable”, {value: daily}, {value: true}); declare(“Device.ManagementServer.PeriodicInformInterval”, {value: daily}, {value: informInterval}); declare(“Device.ManagementServer.PeriodicInformTime”, {value: daily}, {value: informTime}); declare(“VirtualParameters.\*”, {value: daily}, {value: informTime}); ---

Yes it would refresh but if there are too many items within that parameter then only the first 10 or 20 would be displayed. I cannot recall the exact amount that gets displayed so I just used “10 or 20” as an example. ---

From this previous discussion, it seems configurable: > [@Device - Number of maximum displayed parameters is 100 - WHY?](https://forum.genieacs.com/t/device-number-of-maximum-displayed-parameters-is-100-why/1269): > > Just switched from 1.2.0beta to latest 1.2.3. Already found some changes, not happy with some, but let’s start somewhere. Why are there only 100 displayed parameters in Device view? One of my devices has 1158 parameters after initial summon.frowning There should be AT LEAST a config option allowing you decide what is the desired maximum. Something like how custom ui.pageSize was solved. I think I found location, where number of listed items is hardcoded, in /ui/components/all-parameters.ts… ---
