If RemoteThing is outline ,how to Convert it's property value to zero?

Hello what exactly do you mean by "cache effect"? You should be able to change a property value in response to a data change event on the isConnected property no problem. Have you tried this and you are seeing issues?

Xiang, are you looking into resetting a property to zero if your RemoteThing is offline/ not connected?

yes,that's what I need.

You need to configure cache time in order to fix this.

cacheTime — Tells the ThingWorx server how to behave when reading a

remote property. This parameter can take the following values:

○ -1 — Indicates that the VirtualThing always sends its value, and the

server should never request it from the remote application. The value

returned always comes from the in-memory cache of the server. Use this

value for properties that are configured to be pushed to the server.

○ 0 — Indicates that every time the server uses the value, it should request it

from the VirtualThing.

○ Any other positive value — Indicates that the server should cache the

value for that many seconds and then retrieve it from the VirtualThing

only after that time expires. This setting is important for properties that

may be accessed frequently by many users. For example, if 100 users

attempt to access a property value within a 10 second period, you may

want to set this value to 30 seconds. That would ensure that only a single

request for the property is sent to the edge every 30 seconds. However, the

value returned by the platform could be out of date by up to 30 seconds.
