I have an issue with triggering a flow from another flow, it seems to me that the subflow is not running. This can be tested with making 2 flows: **Flow1** When: When this flow is started Then: Activate Flow 2 **Flow2** When: When this flow is started Then: Create a notification with “some text” When executing flow 1, I do not get the flow 2 notification, but when I execute flow 2, I get the notification. Any reason for this not working? ---

I’m not sure because I use Dutch language, but maybe you use the wrong flow card. In Dutch there is “start flow” and “schakel flow in” which I think is activate. If so, activate does not execute a flow but it enables it. Try the other card 😀 ---

I have a similar problem. I would like to start the Flow B only if Flow A started. Is that even possible in Homey Pro version 2023? ---

I my case I to call from Advanced flow “A” by using flow card e.g. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/6/f61eed7c6a23db3dbf5be83df6f409d65c5b0793.png) and then on Advanced flow 40.511 start-card (do this before flow A card…) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/9/69e9bb83c191206921861c7305fbd18ece62221e.png) Or you meant something different? ---

Assuming you mean that “true” as long as Flow A is running (i.e. around 2min)? One option is to start timer on flow A (just examples from mine, use e.g. 2min instead) : ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/8/a8d89d7077e8d132335cc123f7f4277c18f520a8.png) and use it as tricker (or condition) in flow B (just examples): ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/5/35cd88bdd67e56bb6d527968b9ec4e373dfe9acd.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/6/a6c2f4ca54c3f5ab08d14b8d9cd31ce3e3932d90.png) Would this work for you? ---

Thanks for your examples. Did I set this up correctly? I feel I’m missing some extra card. ---

No ALL block after multiple triggers Triggers probably never trigger at the exact same moment Use an ANY block instead, or just connect both cards to the next one (ANY is fully optional).

> [@Kam](#): > > …false dot/option on my “timer is running” card. Use “when” card , take input from tricker, cont. flow from false (marked with red in 👇 ) : ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/a/3a9ffd8610a59144c052c147469682ef017a3410.png) Many other ways also to do the same, e.g. if want to have no extra Apps, you can also (sorry for “wireframe explanation”, but just in case needed…) - create new variable varA (e.g. number-type) - add logic-then card to set varA to 1 (at last part of FlowA) - add logic-when card to check varA (on FlowB after desired main tricker) - set varA to 0 on suitable location (e.g. new flow tricked at 24:00) I hope this helps 🤔 ---

Flow A only runs if someone rings the doorbell between 18:20 and 18:40 on a weekday. And you want to run flow B at 23:00 only when flow A has run? Then you should create a YES/NO variable ‘someone rang the doorbell between 18:20 and 18:40’ FlowA WHEN the doorbell rang AND Time is between 18:20 and 18:40 AND it’s a weekday THEN set variable ‘someone rang the doorbell between 18:20 and 18:40’ to YES and the rest of your flow FlowB WHEN it’s 23:00 AND logic-card ‘someone rang the doorbell between 18:20 and 18:40’ is YES THEN set ‘someone rang the doorbell between 18:20 and 18:40’ to NO and the rest of flow B ---
