Not sure what you mean here…?
I have several of these timers in rules which track increase/decrease of temperature, humidity and barometric pressure. They run up a counter on each change until a time limit e.g. 10 continual increases in 3 hours represents a rapid humidity increase and then triggers an Alexa warning on change in weather conditions. They then reset and so on. These are first versions, with no ‘reset to’ button and not even the add2, subtract2 fields.
I comment as the later version, I have a Presence Detection and another running random lights (with Mariano’s Random Mirror) are Ok, but these older versions are just not running for a few days now. True I should look at the rules and find out why, but I asked you in case it’s a problem of version out of date.
UPDATE
The version has no influence - no reason to believe that there is any issue there. 
Still unable to discover why after several days, starting and stopping the timer manually a few times, they started running again. 
Has coincided with the problem this last week on Location modes - well documented on another thread - and although I can’t find the connection its the only thing I can think of.
