@Kyrcio Is the new version gonna be submitted to the appstore? maybe as test? ---

I started using the prometheus app to store solar panels information and visualize it in Grafana. Is there a way to make a selection in the data is stored? I do only need two sets of data and i am collecting way more now with everything from my Homey. Is there some setting in the config file (.yml) where i can specify what to scrape? I allready set the interval to 5 minutes. ---

Does anybody know how to get the data from pometheus back to Homey? 🙂 I would like to have the following flow: when: it’s start to rain then: write me a push msg with all open windows `curl -s "http://prometheus:9090/api/v1/query?query=homey_device_alarm_contact>0" | jq -r '.data.result[].metric.name'` The tricky part is how to parse the json from prometheus in homey. Query works perfectly on my laptop though. ---

You can use the [HTTP request flow cards app](https://homey.app/en-gb/app/com.internet/HTTP-request-flow-cards/) to perform the query and extract the data with its JSONPath support. You can use [http://jsonpath.com/](http://jsonpath.com/) to test JSONPath queries against the data that Prometheus returns. ---

You could also have a look at using the Alert functionality within Grafana to do the heavy lifting, instead relying on webhooks. > **[Alert notifications](https://grafana.com/docs/grafana/latest/alerting/notifications/#webhook)** > > Alerting notifications guide I have not used this in the context of Homey, but I have been using Grafana Alerting in some enterprise application I have been working (during my day job) and it sometimes does the job well if you can overlook the somewhat quirky setup process. ---

I uninstalled the app around 9 pm yesterday, and the system load is significantly lower since then. Anything you can optimize in your code to reduce the load maybe @Kyrcio? I really love your app, but it takes my average load above 1 😯 As you can see the app started working on June 25th, and I uninstallled on June 29th. ![20200630_091228](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/1/414efed15f613c2f8fc1c966520b4c17548b92fe.png) ---

Could you please install dashboard 10586 and paste back what it spends CPU time on. I think last time I saw this, the physical storage of the Homey was slow due to a hardware or OS issue IIRC. The new polling should also be much nicer on the system so this is potentially a new issue. ---

I already de-installed prometheus. So I need to set that up again, including grafana to get the dashboard running. Maybe if I’m realy bored I will try that 🤔 Edit: OK, I just got bored. Dashboard 10586 is running. So now what do you need from me? ![2020-07-01](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/3/d36ab9f0406751a9f3093c0adb085af048eb0d71.png) ---

Hi @Gruijter If i compare yours to mine, the time spent per device seems factor 10 higher. this was the case on my homey too, before the change below. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/8/c8f9dd7404a3024f1aaf7d51d870823566ef9cb1.png) Can you try this: edited this line (in the app.js file) : ```auto setTimeout(this.updateSystemInfo.bind(this), 30000); ``` To this: ```auto setTimeout(this.updateSystemInfo.bind(this), 300000); ``` after i made that change, my load went down. ---

@Gruijter The problem here is that your Homey spends lots of time refreshing devices. Normally, updatedevicelist and registerdevice times should be more or less zero. I suspect that there is something (an app?) that cause the Homey to spam device changes events. Can you please create a diagnostic report for the Prometheus app and send me the UUID for it? @matrover Actually, the system info loops looks quite normal. Of course it will always be a trade off between update frequency and system load. Note that this metric has its own y-scale in the chart, and that time spent does not equal system load (lots of async calls to the Homey APIs). ---

Thanks. I can see that the device update event is indeed triggered very frequently. I would have to add more logging to get a better understanding of why this is happening. ---

well, I have a lot of devices that each have a lot of updates 🙂 E.g. my power plugs update every 10 seconds, and I have around 30 plugs or so. And another 50 devices updating every minute. And then I have apps monitoring these devices and turning them into new virtual devices. like the PowerByTheHour app. ---

@Gruijter It is not the state changes that trigger device update events ([https://developer.athom.com/docs/api/HomeyAPI.ManagerDevices.html#.event:%22device.update%22](https://developer.athom.com/docs/api/HomeyAPI.ManagerDevices.html#.event:%2522device.update%2522)), rather updates to device metadata. I have created version 0.2.7 which improves logging (in addition to a larger timeout on device updates). Could you please try that and do the diagnostics report again? This should at least tell us which driver is the culprit.
