Hello Arjan. I have a sugestion. Is it possible to make a virtual battery? Or a virtuel akumulator tank? Then we can type inn min/max temp, volume, %alcohol etc then the app can calkulate the amount of kw stored, also the amount needed. This can be used as a Ā«smarttankĀ» and for example the power company Tibber can control this and ā€œsmartchargeā€ at nigth. šŸ˜‡ They now give 20% discount on the electric bill when eletric car charging with easee chargers, so it would be almost the same consept. They then control when the charging starts and stops at nigth. ---

Hi Arjan, Iā€™m currently working on a new Homey app about personal weather stations. I already use you app so I knew a nice icon for the app. I use the sensor-icon from your app. Is that OK with you? ---

Hi guys, thx for this app, its amazing! I have one problem, can you help me? I have flow - every 5 mins actualize temperature on virtal device. But it ends with error: [https://homey.app/f/HDdtkx](https://homey.app/f/HDdtkx) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/7/37e4e7a9c9c762eee91831e0a12bdd9a800a52e8.jpeg) ---

Hi guys, is it possible for a thermostat device to clear the target\_temperature value via flow? I guess there should be the way as this (empty state) is the state of this parameter immediately after creating the virtual thermostat, but I canā€™t figure out how to bring it back once target\_temperature was set to any other valueā€¦ Iā€™m basically looking for a way to remove the temp display from virtual thermostat tile from time to time. ---

@leman I get the idea, but I couldnā€™t simulate itā€¦ How 'bout setting a bogus value, like 123? A temp which in real life never can be reached? ![Screenshot_20210322-001829_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/e/aece363cba5f8c997288c165a2e5cab18a7475bb.jpeg) ![Screenshot_20210322-005856_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/5/e519c812ea12cd6b8b5b6504cb7cfb6b0a554805.jpeg) And you have to round your input values to 0.5 F.i. like this ![Screenshot_20210322-005641_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/c/7cb30c6fc22978d8cf601fe9ded883b42f4e5531.jpeg) ---

Not sure if I get your suggestion correct, but if you set target\_temperature to a value high enough that it is out of thermostat range (as indicated when adding the device) then this card is simply not executed within the flow. So setting an unrealistically high value would either keep previous value (if itā€™s out of range) or update to this new value (if itā€™s in range - however non-realistic / never achievable temperature in a real life this is). It never seems to revert to no target\_temperature value at all (which is the case when the thermostat device is just created). ---

First about your last sentence: that I could not achieve. Maybe it can be done by using Homey script. I forgot to tell you the virtual thermostat I created to show snowfall in mm, was set to a range from 0 to 200Ā° Thatā€™s why the "snow"tile can show 123 as a value. It is correct when sending an out of range value, the original value is unaltered. The only way to adjust the range is to create a new virtual thermometer and setting the desired range. ---

OK, thanks - this is somewhat similar to what I have implemented now (showing dummy value when Iā€™d ideally like to have noting shown at all). In my case the display is for the trigger of various heating plans (automatic/heat/cold/off), and sine in automatic mode there are different thermostat groups with different schedules there are certain time periods when a single target temp display (as available on a tile) is senseless. In such cases I set target\_temperature value to 0, but I would ideally like no value shown at all. Homey script is a bit above my level of understanding currently ))) ---

With a bit of tinkering - apparently you can assign an empty value to target\_temperature when changing the device parameters in Homey Developer or creating a flow in Homey Flow. This takes out the temperature display from the tile completely until you assign a valid value to target\_temperature once again. Flow editor in the mobile app does not allow doing this though.
