Scheduler and Polling quits after some minutes, hours, or days

@Ron

I wonder why ST support doesn’t know that polling doesn’t work.

It never worked reliably. Support just has no clue. See this

Polling not working for custom Device Type

I have created a custom Device Type and specified the capability “Polling”. Also wrote a poll() method. But the problem is that it is never called. When I manually refresh, it is working and the value is updating. I checked the log also and nothing is there, if I manually refresh the log is coming. I saw couple of posting regarding this here but no concrete answer is given, could some help me to figure out the issue?

Poll command not working

I have a device handler with polling capability. However, it looks like the poll() command is never being called. Ideally, I expect it to be called every few minutes. Is this a known problem?

Inconsistent Polling Intervals

A question for SmartThings developers. I wrote a device type that uses poll() to update its status. What I see from the logs is that poll() is being called on average 4 times per hour. But the poling intervals are not evenly spaced, i.e. instead of regular 15-minute polling intervals I see poll() being called at 00, 20, 30 and 50 minutes. For example: 7:00PM, 7:20PM, 7:30PM, 7:50PM, 8:00PM, etc. I could understand if ST tried to randomize polling schedule to avoid peak loads, but the polling times are always the same, they just play this weird syncopated rhythm. Is this by design?
