Thanks. That thread is a bit of a nightmare, but will be a great resource as things progress. For now, I’d like to keep it way, way, way simpler. I would be happy with hard-coded values for one relay with an on time and off time each day. if time = xx relay on if time = xx relay off

You could use the timeAlarms library for that, or alternatively compare values to the built in time functions: https://docs.particle.io/reference/firmware/photon/#time

Thanks! That really got me a good start. I looked at the Timealarms library and it seems to fit the bill at this stage. For now, I setup a single timer to turn on relay 1 and relay 2, as both are connected to lights. I want the relays on for 20 hours, and off for 4. So I used one alarm that wil…

[image] vinistois: nothing related to the timer goes into the loop afaik Actually there is. You need to call Alarm.delay(unsigned long ms) in loop() so that the alarm gets serviced.

well the code doesn’t seem to work, the relays are not responding at the programmed alarm times.

Hi @vinistois Can you show us your whole program? In particular pay attention to the advice from @Ric above to call Alarm.delay(1); in your loop() section. The way the alarms work is that they cannot fire unless you do this.

I really appreciate your assistance. I do have that in my loop, but I think I may be having other issues. They don’t have anything to do with this topic so I have another thread. Once that is sorted out I will try again. In the meantime, here is the code in entirety. The D7/led stuff is an atte…
