Maintenance #

Once a system is up and running, it is necessary to monitor that the system operates properly.

System Cast #

You can set up System Cast to monitor the operating status of the device. System Cast is a mechanism for notifying events related to device operation status such as OS restart and network connection / disconnection.

System Cast only provides a mechanism for throwing notifications via webhooks, so you need to prepare a service to receive the notifications. For example, standard cloud service work tools (Slack, Microsoft Teams) can receive notifications from webhooks. If you use such a service as the Cast Destination, you do not need to develop a new one, and you can notify by just setting.

Disconnected and Connected can occur in a short amount of time, but it’s a network interruption and is not a problem.

If OS Rebooting occurs repeatedly, you need to take action. It is necessary to decide the response flow as to who and how to confirm and decide the response when these events occur.

Update #

Software updates are essential for the safe use of IoT devices. Here are some things to keep in mind when updating.

Firmware Update #

Firmware Update updates the basic software that runs devices. There are two ways to do a Firmware Update.

• Update Manually
• Use automatic firmware update

When updating manually, if your network is poor and updating multiple devices at once, the network bandwidth may become insufficient, and the system may become unstable. So it is necessary to do it separably as much as possible.

An Act stops working during the Firmware Update, so you need to do it when you can stop tasks on devices. In the automatic firmware update settings, you can specify a date when the firmware update will not start.

Act Update #

Once an app is released, Act Update will be available. It’s a good idea to keep it as up-to-date as possible, as bug fixes and machine learning model improvements will be made. Act Update must be done manually.

It is up to the app vendor to ensure app compatibility during the Act Update. Therefore, you should update one unit first, check that it works as expected, and then update the rest. You will also need to check (visually check) the compatibility of the settings, and if not, re-update the settings on all devices.

Whether the data is being sent correctly #

Rate Limit #

Rate Limit is a mechanism to limit Cast’s frequency so that the external service to be Cast does not receive much access from Actcast, and the system becomes unstable. You should monitor whether the Rate Limit is blocking transmissions of data. You can see the number of Rate Limit Exceeded on the Activity Log of the Act Dashboard.

If your Cast is limited frequently, you need to develop a Cast Target Service by following the specification and relax the restriction.

App is deleted #

An app may be deleted at the discretion of the vendor. The deleted app will no longer be available after 30 days.
