v1.61.5

Fixed

• A device's firmware and model could briefly read as empty and then come back. When one part of a poll timed out, the manager stored blanks for the RouterBOARD firmware, board and model instead of keeping what it already knew. On screen the gap lasted a single minute and passed unnoticed, but anything watching through the API — Zabbix, a webhook, a dashboard — saw the value disappear and return, and could raise an alert for a device that had not changed at all. Those fields are now left untouched when a poll cannot read them.

Changed

• Zabbix template: sensors are discovered per device. CPU, temperature, voltage and power items are now created only for devices that actually report them, so a cAP with no sensors or a cloud router with no temperature no longer leaves items stuck in an error state. On a 25-device fleet that is 472 items and none unsupported. The template also survives a manager that has not yet been updated with the fix above.
