I am an absolute beginner: My need is very easily explained. I want to save my temperature and humidity readings in a log file. I want to export the file to my computer. (manually or automatically) Anything else is a bonus. I checked the apps and there are some using “loggin” in the name, but I do not understand how to use them. Can someone help please. ---

Sure. Use the [web app](https://my.homey.app) go to ‘Insights’, right click on a device and choose ‘download’. ---

You can use [PaperTrails](https://homey.app/de-ch/app/nu.dijker.papertrails/PaperTrails-Logbuch/). The log can be e.g. viewed, filtered or something else in Excel after download. [PaperTrails](https://homey.app/de-ch/app/nu.dijker.papertrails/PaperTrails-Logbuch/) can also send the log with mail or save to a syslog-server. ---

I use the [InfluxDB app](https://homey.app/nl-nl/app/homey.influxdb/InfluxDb/) to export the data and use it in a Grafana dashboard. The advantage is that you have always the detailed data available over a long period of time instead of Hmey’s InSight. ---

Ok. That is simple enough. But If I have 5 sensors, I have to do it 5 times. Correct? As I mentioned, I am a total beginner. Is there any way to save the combined chart in insights in the web app? Or do I have to select my sensors all of the time? ---

After some tinkering, I understand I have to create a flow to do this. I do not fully understand how to use PaperTrails. If I add the card “add to the log” how am I supposed to pick the sensors I am interested in? Is there a global token for each sensor? How do I find out which one that is? ---

You need one Flow. When you building Flows with iOS- /Android-App: In WHEN use the Device-Card SENSOR VALUE changed with HUMIDITY. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/7/c74f3009fd30e41bab34281b0c9fbc7bbd54d581.jpeg) In AND for each Sensor wich should **not** logged use one LOGIC-Card with CONTAINS and the name of the Sensor. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/7/97785d5280a296dc10a6834ebf021b0e1ffc3833.jpeg) In THEN use PaperTrails-Card SAVE TO LOG. In this card you can set what to log e.g. Sensor-Name and Sensor-Value. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/f/dfa721156cd99eeab89a9466276fbeb2aedf7d21.jpeg) ---

As simple as it is with InfluxDB. All insight measurements are exported, even if you have multiple sensors. [https://homey.app/f/sAhaCM](https://homey.app/f/sAhaCM) You can get something like this ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/f/0fc645f0678b9cbc590299fa305e303b337c58fb.jpeg) ---

Hi I saw your solution, I’m a noob here but how do I do to see the log ? If I use that app and flow you showed? @Arnold_vd_Linden ---
