Petsafe integration not triggering 'feed' button

[davel4wa]

This is a ver. 1 SmartFeed device. All or most of the entities generated report correct status or in the case of unavailable functions such as 'food level', a reasonable status. The 'button.feed' entity does trigger the button.press service but the feeder does not respond. The logger does report the action. Some of the 'switch' entries work but the status is reported with significant latency. For instance, if the 'child lock' entity is triggered, the toggle shows 'on' then after a few seconds returns to 'off' then after 5-6 seconds returns to 'on.'
The major issue here is the 'button.feed' entity does not work at all. Calling the 'button.press' service from the Developer Tools page has the same result. There are some log entries that may relevant.
