Is there a way to have a virtual sensor in Homey that get’s its value from mqtt? Either that or set it via some http request to the homey? I want to write a value to a virtual sensor in homey so I can use it in flows. ---

Yes, like this: ![bild](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/a/4a25e759ad14fcd84814ed6bba0a8d7c6702ba4b.png) ---

Thank you. What do you use for virtual sensor? I’ve only found virtual switches in the homey. ---

I’m not using the built-in virtual devices, instead I use this [app](https://homey.app/sv-se/app/com.arjankranenburg.virtual/Virtual-Devices/) ---

I tried that app, but I’m unable to set the virtual sensors value. I’m running firmware v5rc50, perhaps the app does not support v5. I can rest the value from the mqtt topic and use both on a variable and a notification. But the value on the virtual sensor does not set. ---

Plz show us the card. ---

The Better Logic variable is set (I’ve confirmed that) and the flow is triggered (the notification is created), but the sensor value is not set. ![Screenshot from 2021-01-02 13-53-08](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/7/d7711fadf54bf67df13e4c920584600a98bc80ec.png) ---

Set value=measure\_power. Plz do not use tags in the first option of the card but type in manually “measure\_power”. Like also visable in the flow cards from @Henrik_Johnsson. ![chrome_2021-01-02_14-13-25](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/6/a6a95b97f63b382abcc260195988ff826131d62e.jpeg) ---
