I want to change the value of a saved flow context several times during a day, for example; 0000hrs == 45 0400hrs == 64 0500hrs == 55 0800hrs == 50 etc, etc... I realise that I could achieve this simply by having a number of inject nodes, all set with the relevant time & value (feeding into a …

@moebius Thanks, but a bit overkill for my needs. Colin's node-red-contrib-ramp-thermostat works well also, so I'll stick with it.

Doh! just hit by a lightning bolt - a ramp-thermostat node!

You could mark this as the solution :slight_smile:

This is how i solve most variable configurations in my flows (although i guess your problem could be solved easier), but maybe it fits for you. To try it you have to change the time in the config (keep the TZ in mind) [Screenshot%20at%202019-04-26%2017-44-18] [{"id":"bd0ad736.9379c8","type":"inj…

[image] Paul-Reed: Colin's node-red-contrib-ramp-thermostat works well also Not mine. I think it a pity that node combines the ramp and the t/stat. I think it would be better as two components, the ramp for profiling anything, possibly in no way related to a t/stat, and the t/stat as a sepa…

No problem - i've learned even something with the sample! Cause the use of a colon inside the topic gave me a hard time (guess because it's internally used as identifier)... :slight_smile:

Ah, my wrong assumption - it's the work of @cflurin But yes, agree Colin. I'm getting around the 'ramp' problem by setting 2 values very close to each other. 0000hrs == 45 0359hrs == 45 0400hrs == 64 0459hrs == 64 0500hrs == 55 etc, etc...

[image] Paul-Reed: I'm getting around the 'ramp' problem by setting 2 values very close to each other. From memory I thought you could make the timestamps the same to get an instantaneous change, so in your example 0000hrs == 45 0400hrs == 45 0400hrs == 64 0500hrs == 64 0500hrs == 55 et…

[image] Colin: but I may be mistaken. No mistake Colin, that does work.

Another possibility using the inbuilt nodes: [{"id":"f4f88c80.c5fc5","type":"change","z":"1d66267b.4c5caa","name":"","rules":[{"t":"set","p":"time","pt":"msg","to":"$substring($fromMillis(payload+36E5),11,5)","tot":"jsonata"},{"t":"set","p":"output","pt":"flow","to":"$exists($flowContext(\"output\"…
