can someone help me out. I only have these commands in Homeyduino, so I can’t find the right card to get the screen to 6 layouts and sleep. ![IMG_7982](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/e/7e6710ced0092ce0b2fe6f57154cb17136ec5f99.jpeg) ---

According to the description, I should use this command, but I can’t because I don’t see it. ![IMG_7983](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/8/d84a314fb61d46015e74ea27a848429075800a5e.jpeg) ---

Those are looking like “AND” cards, not “THEN” cards. ---

The second card “ (actie) text gelijk aan (waarde)” is the same card as “Actie (text) “? So i get then (Dispkay\_Mode) text gelijk aan (horizontal 6) Display is now changing to horizontal whit 2 rows of 3 bloks a row? ---

I’m trying to preserve the battery drain and wake up the screen every 15 minutes to get the new values. However when I’m not at home it is not necessary to refresh the screen. Is there a way to realize this? So only wake up every 15 minutes when my status is at home. ---

What is the problem? Make a flow exactly as you describe your problem: If: every 15 minutes and: I’m at home then: start the update ---

That’s not working as wanted because the device is going to sleep. When it wake-up the flow is triggered. Now I want the device go to sleep when I’m not at home and wake-up when I’m back at home. ---

Devices that are sleeping, normaly can’t be waked up external, so you have to wait until it is waking up itselves, and then decide if update should be done, I’ m not sure if update is always nessesary at every wake-up. I don’ know all the details of this device, sorry. ---

There is no way to tell the device to stay asleep, when it is asleep. Only to lengthen the sleep time when it wake’s up when you’re not at home. Problem is, that when you’re coming home, it takes longer to wake up, update and shorten the sleep time. Only solution i can think of, is that the device can be put asleep immediately, without updating the screen. That saves e-ink refresh power and shortens the awake time. I would love this possibility (also for when you’re asleep yourself). @sebyldino do you think this is possible or can be added? ---

Hello, when esp is in deepsleep, it will wake up only when the deepsleep time you configured is up. (Or reset esp with the reset button). Esp does not execute any code during this time. But if you have regular absence hours, for exemple 8 am → 8 pm you can create flow start on the first wake up after 8 am to define a deepsleep until 8 pm. And at the wake up redefine the deepsleep time to 15min. ---

Yes that is also a possibility, but less convenient, because the times that you are away from house are not always predictable. What I was thinking of is that current working is that the device only goes to deep sleep after all values are updated. Could you add a command that put’s the device to deep sleep? So this is controllable from homey? ---

Thx for the responses 👍🏻 I think I will go for setup my flow to check if I’m at home. If YES then update all cards, if NO then stop the flow. And see what this will do with the battery life time. ---

> [@Arnold\_vd\_Linden](#): > > if NO then stop the flow. I’m afraid the device doesn’t put itself to sleep in that case. But you can try, I’m interested in your findings.
