The History on the ElkConnect App is the History in the Control Panel. This includes panel based history.
The Event List on the ElkConnect Web Portal is the notification event list. This includes events that are sent via notifications from the system through the cloud. This list notes the events, even if you have opted to not receive them via Push, Text, or Email.
I assume the truncated list you are referencing looks like this or similar.
Here is a similar list from a web browser on a 22′ monitor.
My assumption is the truncated message is due to a mobile or tablet browser. There is no additional information offered by clicking the entry, this is a image as you noted.
The “Event ignored – Notification globally ignored” entry indicates a “Automation” Alarm event. This event is still communicated to the cloud, but it is currently ignored by the notification server. Automation zone alarms do not get forwarded to user notifications, at the moment. This is there as a place holder for allowing the option of these events to be sent in the future. As we build out the site, we will be adding more options for what events are sent and what events are not sent. Due to the way Automation zone types are used, we are ignoring them until the selective filtering is implemented.
Additional, once we implement web based configuration of the control by the installer, we will allow for the control history to merge with the cloud event list. The cloud has a larger storage capacity and will allow for a larger log. This effort is current in progress.
