hello! I wish to be able to run a flow at any time, that will start a lamp the next coming time it gets 6am. But I only want it to do it once. Just to get a better picture. I have a light that normally turns on at 9am. But once in a while I want it to turn on 3 hours earlier the next day, but I only want this once every 4-8 days, so it would be perfect the be able to start a flow that enables early turn on just once then the day after that it automatically is back at 9am. ---

Flow1 WHEN this flow is started Then enable this flow “flow2” Flow2 WHEN the time is 06:00 THEN switch light on Disable this flow “flow2” (delay 1sec) Disable this flow “flow3” Flow3 3 is the flow that currently switches on the lights at 09:00 I bet someone at this forum has even figured out a way to have your agenda appointment trigger this… ---

Or… use the variable. One scene/flow/button which one set’s the variable “EarlyBird” 😉 Then a timer-based flow at 6:00, which one checks the “EB”, and switches, if done. Another timer-based flow at 9:00, this one checks, if not “EB”, then switches light; otherwise clears “EB” (or… the EB clearing in a separate flow - for example @ 10:00 ) PS. In general, the both (variable/flow disable) possibilities are equal 😉 But, there may be some local side-effects to prefer one or another solution. ---

If I didn’t make a logical mistake with the numbers, the following flow should turn on the light at least 4 times at 9:00. It depends on a calculation of a random number between 1 and 4, when the light will be turned on at 6:00. So it can be on the 5th, on the 6th, on the 7th or at the latest on the 8th day. After the light was turned on at 6:00, the next day the light will be switched on at 09:00 again for the next 4 days. For the flows you need 2 self created numeric variables (More → Logic). For the first variable _ **CL\_RandomLight** _ please enter the value 1. For the second variable _ **CL\_RandomLight1** _ please enter a value greater than 4. Of course you can name the variables differently. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/b/4b8e6e07d3ce639d5f358f46dc0e3d9de55b6d53.png) These flows will also work with the “Standard Flows”. Sorry for German language in the screen shot. If you don’t understand something, just ask. ---

I don’t understand the context between the question in this post and the ICalCalender tutorial. Could you possibly explain this? ---

Reading back, good question. For some reason in july I replied referring to a calender appointment. But looking at the question indeed dont see why anymore…
