Hi, I’m creating a flow to control a blind, and I need the blind to activate when the sun reaches a certain position based on altitude and azimuth. I’ve drawn the flow but don’t know how to activate it. Any help? Can you translate it using Google Lens? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/c/ac186deb924f75ee641add3a2a48a1f7a88a16ef.png) ---

You can’t use multiple ’trigger’ cards with an ’all’ logic. This is a common question here. > [@Developing flows: tips and best practices](https://community.homey.app/t/developing-flows-tips-and-best-practices/117362): > > Note: It is based on personal preferences, but this may help you to assess what works for you and develop your own style. Various links to specific solutions/flows in this community, You will see in past and present examples an evolution from simple flows to advanced flows and various styles. A number of apps mentioned (eg. Advanced Triggers, Advanced Virtual Devices) are best used when you have some experience in flows. Avoid starting flows at a specific time; other triggers are preferred. A… ---

Is this correct? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/f/ffadec2d1b648c3fcbc0560c7d3af56c341a9128.png) ---

Please have a look at the [[FAQ][Advanced Flow] Infinite canvas. Infinite creativity](https://community.homey.app/t/faq-advanced-flow-infinite-canvas-infinite-creativity/65145) topic, how to create Advanced Flows and where you need to pay attention. Every flow starts with a trigger flow card (When…). You used conditional flow cards (And…) first. There are multiple ways to create your flow. Example 1: Every 5 minutes ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/a/aa318b8cb41207d447a657e5847b5810965d86bd.png) Example 2: When azimuth or altitude changes ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/2/b26cd825e7d67e1c4e8f4885334f8f75d826d1e5.png) * * * **Edit** > [@Skalmenar](#): > > Is this correct? Yes, this Flow will work. However, the flow is only triggered with every azimuth change, altidue was not taken into account. But I think that will be completely okay. ---

You miss the “end” Azimut value, now it starts the rest of the flow from azimut 136 until 360. But I don’t know if that’s intentional. I also use it to open the blinds, I added a timer, to prevent the blinds from going up and down with each little cloud. (I try to avoid ALL blocks, because for me, it makes flows harder to read) (Edited) Example: ![1000000687](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/3/3379304dbbefbdf65c45032e8edd4cc5fa822ba2.jpeg) ---

Shouldn’t the card read that the timer **isn’t** running? ![IMG_2129](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/1/4137e3893e70c92180ac3a70fe52f85dc09fb057.jpeg) ---

You’re absolutely right, thanks! I’ve updated the screenshot.
