Review daily changes in Ably presence
See what changed since the last snapshot with a scheduled Python comparison.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Execute Code
Execute python code in a sandbox and return any result, stdout, stderr, and error. use /home/user folder to write/read files. try to not use plt.show() as the code is executed remotely. use files for image/chart output instead.
Why this helps
Without a saved prior snapshot, it is hard to tell whether today's channel presence is routine or different.
- Compare current and prior snapshots when both are available.
- Surface additions and removals in a concise report.
- Save the output for later reference.
Setup
Build it in a few focused steps.
- 1Connect Ably and Codeinterpreter once in the Notis portal.
- 2Create an automation in the portal or tell Notis in plain language from any channel.
- 3Describe where current and prior snapshots are available and how to report changes.
- 4Choose notis_cron as the trigger and select where run reports should go.
- 5Test with one real pair of snapshots.
Questions about this workflow
Can this calculate a delta without a previous snapshot?
No. The comparison requires a prior snapshot. Make it accessible and tell Notis which snapshot should be used.
Does Ably provide a built-in presence change trigger here?
No Ably triggers are listed. This workflow uses a recurring Notis schedule.
What changes can it report?
That depends on fields in the snapshots. Specify the member or presence attributes to compare and include those in the available data.

Ably triggers
Codeinterpreter actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create Sandbox
Create a sandbox to execute python code in a jupyter notebook cell. this is useful for agents to communicate, execute code, see output, read files, write files, etc. it's like you own personal computer, but in the cloud. use /home/user folder to write/read files.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Execute Code
Execute python code in a sandbox and return any result, stdout, stderr, and error. use /home/user folder to write/read files. try to not use plt.show() as the code is executed remotely. use files for image/chart output instead.
Get File
Get a file from the sandbox and returns the file. the files should be read from /home/user folder.
Run Terminal Command
Run a command in the terminal and returns the stdout, stderr, and error code. use /home/user folder to write/read files.
Upload File
Upload a file to the sandbox environment. the files should be uploaded to the /home/user folder.
Connect any two apps with Notis in the middle.
Ably and Codeinterpreter, or any other combination from 1,000+ integrations.
