I’ve just spent a very frustrating evening trying to convince my Cores to light one LED if it’s after 7pm in the evening and before 7am the next morning and then light a second (different) LED for two hours from 7am-9am. I’ve tied myself in knots with if, else, else if statements, < > and even time…

if (Time.hour() < 7) ledOneOn(); else if (Time.hour() >= 7 && Time.hour() < 9) ledTwoOn(); else if (Time.hour() >= 19) ledOneOn(); else ledsOff(); This takes care of the case from 00:00 to 06:59 07:00 to 8:59 19:00 to 11:59 Double-check me on that, but that might do for you.

You may find this discussion interesting (found via forum search "certain time") [image] Doing something at a certain time General Hallo, I’m wanting to execute a line of code on the hour every hour apart from at night. Can I do it like this: if(Time.hour() > 7 && Time.m…

thanks @scruffr and @heng this seemed like a really good fit for something I’m trying to do as well - so I’m trialling the code - but I found it didn’t work for me and was still showing a red LED at half past eight this morning, when I reset the Core (simply wondering what state it would boot up in)…

Have you considered my approach at all? I have never had any issues setting any arbitrary time frame with the seconds based range. I wrote that rather elaborate post to make people understand how it’s done and how to build their own solution with that paradigm in mind - not as a copy/paste solutio…

Hi @Scruffr I have considered it, understood it(!) and if necessary I will definitely go for it but because I don’t need to do things anything other than for the complete hour (ie I have no need for ten past four or quarter to five, I’m only interested in if it’s within the hour of four pm etc) I wa…

Two things, are you making sure the time is being set from the server? and you forgot a curly bracket: if (Time.hour() < 7) redLED.on(); else if (Time.hour() >= 19) redLED.on(); else if (Time.hour() >= 7 && Time.hour() < 9) greenLED.on(); else { redLED.off(); greenLED.off(); } Also, …

[image] HEng: Also, I hoped it would be clear, but redLED.on() needs to call greenLED.off() and vice versa. if (Time.hour() < 7) //time between midnight and 0700, red LED ON! redLED.on(); greenLED.off(); else if (Time.hour() >= 19) // time between 1900 and 00:00, red LED ON! redLED…

For compactness and readability sake I think you could turn: if (Time.hour() < 7) //time between midnight and 0700, red LED ON! redLED.on(); greenLED.off(); else if (Time.hour() >= 19) // time between 1900 and 00:00, red LED ON! redLED.on(); greenLED.off(); simply into: if (Time.hour() >=…

[image] daneboomer: Edit: I need curly brackets around the if, the else if and the second else if as well don’t I?! Yes, if() will conditionally execute the next statement or block. So if (condition) greenLED.on(); redLED.on(); will only execute greenLED.on() if condition is TRUE but will a…

[image] HEng: if (Time.hour() < 7) ledOneOn(); else if (Time.hour() >= 7 && Time.hour() < 9) ledTwoOn(); else if (Time.hour() >= 19) ledOneOn(); else ledsOff(); Thanks - really learning something @HEng and @…

Especially once you don't want to go for full hour boundaries you'll get yourself in a pickle with the most obvious solutions
