ive had a raspberry pi sitting on a shelf for 1 year monitoring a google inbox for email status. unread emails trigger a lamp to turn on. this has work perfectly for one year. i could go to the email account and mark an email as read or unread and the imap sensor would update in about 5 seconds. the ha installation was not touched or updated during the first year.
About 3 weeks ago the time it took imap to acknowledge the email accounts unread status started to very greatly or not update at all. ive trier updating HA and tested using other email accounts with the same results. reloading the imap sensor does read the inbox status accurately and repeatably.
Any help is greatly appreciated.
