### Coming soon: Chronographs can be directly reflected on Advanced Virtual Devices from the [Device Capabilities app](https://homey.app/nl-nl/app/nl.qluster-it.DeviceCapabilities/Device-Capabilities/): So, no more flows needed to set the field of an AVD based on a Chronograph timer/transition/stopwatch. > [@\[APP\]\[Pro\] Advanced Virtual Device (Device Capabilities App) with Unique Text Status Indicator](https://community.homey.app/t/app-pro-advanced-virtual-device-device-capabilities-app-with-unique-text-status-indicator/68198/253): > > Coming soon to the [Device Capabilities App](https://homey.app/nl-nl/app/nl.qluster-it.DeviceCapabilities/Device-Capabilities/): Reflection of Variables or Chronographs in AVDs! You can now (well, when it’s published) select entities from other apps to be reflected as value of the AVD field! For example, let it reflect a [Better Logic Library](https://homey.app/nl-nl/app/net.i-dev.betterlogic/Better-Logic-Library/) variable: Or let it reflect a [Chronograph](https://homey.app/nl-nl/app/nl.fellownet.chronograph/Chronograph/): Here the Elapsed time is formatted with the BLL expression to fit the textfield with a nicely timestamp.

Amazing work. Small request: would be very nice to see when a chronograph was last used, similar to the countdown view. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/7/37ae327aa415d4f0e7ccf5fdd6243f254cdc87d3.png) ---

### Update: Issues on older HPs with an extrem amount of running Chronograps, seems to be resolved in the latest version. Multiple reporters have stated this morning that it is working again as before. Meaning: The few extra properties made it just to much every second. Currently, the properties are still there, but instead of before, where each updated chronograph was send through realtime each second, i now collect the updated chronographs and send them in one realtime message. This seems to stop it from overloading when having such amounts of running chronographs. If someone still has crash-issues (on older HPs) let me know! ---

What info is updated every second on running timers/stopwatches and what is it used for? Some time ago you explained to me that Chronograph only did some (too much) work when the timer/stopwatch was ended/started/reached transition? Updating every second sound waist of resources? Or am I missing something? I am a sw developer but has no knowledge about implementing in Homey. Please enlighten me. 🙂 ---

> [@Anders\_Gregow](#): > > Some time ago you explained to me that Chronograph only did some (too much) work when the timer/stopwatch was ended/started/reached transition? Indeed, that’s what i thought. And it still does very little internally, but i later found that it did send realtime messages over the API, ofcourse, for the App Settings. This remained, and is still in use. I just added 2 properties, elapsed and remaining, so it can be used by AVDs. Altho this caused an issue (with users on hp2019 running a couple of dozens to a hunderd chronographs at once. Those now work fine again btw!) and i now changed how this realtime message is send. Nothing is updated every second, only a message is send over connected APIs (like appsettings or the AVDs) with an array containing running Chronograph with a few properties. Only difference is now, i made the specific realtime message send one array, instead of a realtime message per running chronograph. When the App Settings are not opened and you don’t have DC installed or the realtime-updates disabled in the DC Settings, then this update only reduces resources (as “can be seen” by the fact that the issues that appeared a few days back, seem to have disappeared with the last update). But i’m sure i can implement a toggle in the Chronograph to completly disable this realtime message, saving (i think in many cases not much) resources, but that would mean that the running Chronographs in the App Settings are not really showing the real Chronographs, but calculated versions of them, like before. ---

Thanks for the explanation. Always nice to understand how things work under the hood. So sending realtime messages when not used will not decrease performance of the Homey, only resources? Is it possible to only send them if someone is subscribing, e.g when the setting is opened? ---

> [@Anders\_Gregow](#): > > Is it possible to only send them if someone is subscribing, e.g when the setting is opened? Technicly, that is already the case, the message is send, but stops because no-one is listening. However, the array is still build about every second when timers are running. This is very little work, but it’s still only used for updating Chronograph devices and keeping the settingspage up2date. Because i cannot know if there are API listeners, and it would be very hard to know if the settings are opened, creating the array (and message) could be placed behind a toggle, for users with a older HP model and many running active. But right now, i am not getting any more reported issues, only that it’s fixed. ---

Okay, Chronographs were not correctly updated in other apps, since my last performance change. This issue is now resolved. Update ([Chronograph App for Homey | Homey](https://homey.app/a/nl.fellownet.chronograph/)) to resolve the values not updating correctly in other apps like the [Device Capabilities App](https://homey.app/a/nl.qluster-it.DeviceCapabilities/) and it’s [Advanced Virtual Devices](https://community.homey.app/t/app-pro-advanced-virtual-device-device-capabilities-app-with-unique-text-status-indicator/68198). ---

Just like i build for Countdown, Advanced Triggers and Better Logic Library (for variables): You can now select any chronograph (timers/stopwatches/transitions) in each flowcard from a dropdownlist. In that dropdownlist, you can also create a new chronograph and select it: It will be created when you press save or run. I also keept the old name field in flowcards, firstly to keep all flows working, and also because you can than still use tags in the name.
