How to deal with stale paths/data

[Ticoda]

There is nothing built in to deal with data that just stops updating. There probably should be.

Meanwhile one way forward is a node-RED flow that outputs a null value if there is no real value for a certain period of time. Google should be able to find references to similar logic.

Many thanks for the quick response. A Node-RED flow had occurred to me but I was wondering if there was an obvious solution "off the shelf".

Looks like I'll have to bite the bullet and start reading up on Node-RED! How hard can it be for an old software engineer?

Thanks again.
