Simplisafe can't set alarm

I’m on the latest HASS 0.113.2 and I can’t seem to get the alarm to set either via the UI nor via the services dev tool.

I have tried both having the “code:” configured in the YAML (both tried the “master pin” and a “custom pin”) and typing the code into the UI or passing it via the services call.

If I don’t provide the code via the UI/services call, it reports " * Incorrect alarm code entered (target state: armed_home): None", if I provide the code, it reports the code in the log report (but still states that it’s an Incorrect alarm code.)

The UI does reflect the current state of the alarm, so it’s not an authentication issue.

Thoughts?
