I had 20 second polling on devices I needed near instant status on that had automations set. I also had 3 minute and 4 minute polling on other switches, the 4 minute was triggered by the 3 minute so they wouldn’t overlap. I experienced lag from time to time with my closet lights that are triggered by Motion, expected them to turn on near instantly but sometimes it would take 20-30 seconds.
I ended up changing out all the switches I was polling 20 seconds with Zwave plus switches since they report physical events which helped a lot. I also installed the zone motion app and use it to trigger refresh so I am only refreshing those devices when someone has been in an area vs all the time. This has also helped.
Hopefully these ideas will provide some help as I have tons of older GE switches that require refresh, over 50 of them. I have a string mesh but the frequent refresh was straining it from time to time.
