Envisalink arm/disarm not working

Configuration
1

I’m using an Envisalink 4 with a Honeywell Vista 20P.

It is detecting the sensor entities and receiving their states correctly, but buttons to arm and disarm are not working. Clicking the button does not generate any info in the log. I have checked previous posts where people were using the wrong alarm code or they didn’t add quotes around the alarm code – triple checked that should be correct. I have also tried invoking the alarm_control_panel.alarm_arm_home and envisalink.alarm_keypress services directly in developer tools. Same result, no error log and it just silently does nothing.

Here’s my config:

Any other tips for debugging this?

What does your Lovelace UI code look like? Did you misspell the alarm entity name by chance?
