This means the thing has to be stopped, changed, and then restarted. This would cause the currently executing service to be stopped and that's why you get "Thing not running".&nbsp;</P> <P>&nbsp;</P> <P>Without testing it, I would assume it works if you move the service to a third entity.</P> Mon, 12 Jan 2026 09:35:55 GMT https://www.ptcusercommunity.com/t5/ThingWorx-Developers/NUMBER-type-attribute-to-create-an-alert/m-p/1050504#M71111 Rocko 2026-01-12T09:35:55Z https://www.ptcusercommunity.com/t5/ThingWorx-Developers/NUMBER-type-attribute-to-create-an-alert/m-p/1050641#M71115 <P><SPAN>It worked successfully using the method you gave, thank you.</SPAN></P> Tue, 13 Jan 2026 11:48:48 GMT https://www.ptcusercommunity.com/t5/ThingWorx-Developers/NUMBER-type-attribute-to-create-an-alert/m-p/1050641#M71115 Snoopy_hu 2026-01-13T11:48:48Z
