Without sealing. It just sticks to the inside wall of the refrigerator. ![20210522_082742](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/4/9410067f5ccd9d80a4aeb888b75f260bd84b5273.jpeg) ---

Nice, I just put one in the fridge still not 100% sure about the freezer, also because low temperatures drain the battery very quickly i would think? ---

My Aqara is running a year in the freezer. No problem with battery. Only problem with the Aqaras I had outside if it`s cold and rainy and humidity near to 100%. Then the cold battery is collecting some condensation water. ---

Inside the fridge it can be quite damp / humid Standard Aqara temp/humid sensors 😉 While it is a humid sensor, it should be able to function in a damp/humid surrounding. Some guys have 'em hanging right over the showerhead, and I got one right under the cooker hood. Working for months now 😉 And don’t put plastic bags around them, while they cannot measure the humidity then (it can’t hurt if you only care about the temp measuring) And yes, batteries in a freezer are draining a little faster. ---

> @Arie_Laxed Hi Arjan, is it possible to add `measure_ph` as sensor value? Thanks in advance. @Peter_Kawa: Thanks for the suggestion, but unfortunately measure\_ph is not a capability provided by Homey. I don’t want to add any custom capabilities, because then I’ll be adding them for everything. ---

I wish to add a own icon, i uploaded a .svg and added the device, but the icon in blank… Are there any specific rules where this .svg should match on? Are there any tools to create a own svg? ---

Hi all, Thanks for creating and maintaining this app. I recently got to use it to create a virtual LED light and use a flow ([link](https://homey.app/nl-nl/flow/ONuO1D/)) to send the command to my ESPEasy connected LED ring. This works pretty well as long as you control the device in the Homey app. However, if I control the virtual device with a flow, I see that the device status changes in Homey, but that the flow above (to actually control the device) doesn’t get triggered. Is there anything I can do to change this? Appreciate your help. PS: Apologies if this has been asked/addressed before. A quick search did not show any results. ---

Hi Rick, It looks like you added a virtual knob / button. Try it with a virtual light instead. This thing can be switched on an switched off. A knob only gives a pulse. Hope this makes sense 😉 The light then must have the on/off capability. ![Screenshot_20210531-130618_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/4/c4283bde5846ae066c5c660583fa0eb813b0f0a8.jpeg) Here an example of a virtual light (read: switch) which is switched ON in an other flow, and triggers this flow this way. The other flow which switches it ON: ---

Hi Peter, Thanks for your help. To my knowledge, I did add it as a light. What I added: Device\>Light icon\>Light class\>Several properties And to make sure, this works: Color change of virtual device (in app) → Flow triggered by change → Command to device (HTTP request) This _doesn’t_ work: Color change of virtual device in flow → Color change of virtual device (by flow) → _(Not triggered)_ Flow triggered by change → Command to device (HTTP request) ---

Just changed it, but same result. Manual change works, change through flow only changes the virtual device, but does not trigger the flow to send it to the actual device. ---

Hi! Been reading along a bit but still new to homey so forgive me if this might be a silly question: I have two Hue lights. I created a VD lamp with hue color capabilities. This VD shows up and I can set its color. Now I am trying to make the two hue lights change to the color I set in that one VD. But I can’t seem to find such flow cards? ---

It sounds like a modus vdevice. That one has an extra card. It can be switched on and off whithout sending triggers. Try to replace your VD with a new one, and make sure it is like: Add Device (NOT modus)\>Light icon\>Light class\>Several properties including on/off My vdevice happens to be a modus type. I can select “Switch it On” and "Switch it On without sending a trigger. Make sure you select “Switch it On” ![Screenshot_20210531-204017_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/b/bbef02b5b3749db0fa58dc7addc7ef907cd76c01.jpeg) ---

This is a test flow to change the color randomly every second: [Gedeelde Flow | Homey](https://homey.app/nl-nl/flow/wNwL3D/) This is the flow that sends the command to the device: [Gedeelde Flow | Homey](https://homey.app/nl-nl/flow/kzvL3D/) Note: Also tried the 2nd flow (again) with the “When switched on” trigger, didn’t work either. ---

Thank you. I think you cannot trigger a flow when a color has changed (I didn’t notice that) The “is ingedrukt/veranderd” is about the onoff state afaik. Here are my cards I can pick as a flow trigger. If color changed isn’t available. ![Screenshot_20210531-204810_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/f/5fbe110faf66aa0f30cd732da2eefd223488e295.jpeg) [Previous page](https://community.homey.app/t/app-pro-virtual-devices-virtual-devices-to-simulate-1-or-more-real-devices/1723.md?page=19) [Next page](https://community.homey.app/t/app-pro-virtual-devices-virtual-devices-to-simulate-1-or-more-real-devices/1723.md?page=21)
