> [@Peter\_Kawa](#): > > time(‘HH:mm:ss’, $value) Well, inserting the value is not needed since a while; if no parameter is given, the $value is automaticly inserted. About 1 or 2 HH, this only means the minimum padding. Like with 6 hours left, H will give 6 while HH will give 06. So it depends on how you want it shown 😉 See the BLL app settings for all examples on the formatting.

Hi all, I need a little help. Is it possible to reflect a boolean of a device in a text field and convert its value to a custom text? For example if the boolean is ‘yes’ then convert to “off course” and if ‘no’ then convert to “off course not”. I can do this from a flow, but is it also possible to do it from the device settings menu by using an expression and call a function that returns the right string? ![Screenshot_20240106-102858_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/c/cc3715e0175d1748d671a1b4286d126934593ce7.png) ---

Do you have more of these handy dandy expressions? Or is there some sort of online summary what I can look for? ---

> [@Dennis\_van\_Dinter](#): > > Do you have more of these handy dandy expressions? Yeah, well, i guess i could explain it a bit more in the app settings: ![Screenshot_20240106_195649_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/e/ceabe0bf56c8cf4c4e96ec89e7857cabd3427e67.jpeg) The expressions are just javascript expressions, with some wrapped around BLL stuff. I have buildin extra modules and methods, and the posibility to create own custom functions to be used in the expressions. But its basicly just JavaScript executions, just as you could do within HomeyScript. But more customisable and usable within way more flowcard for putting stuff in variables etc., PLUS you can use all that either within textarguments in flowcards from other apps that include BLL coding, or in BLL expression fields, like in Device Capabilities, Google Services, FTP client, Simple (Sys) Logging, BLL itself, etc. > [@Dennis\_van\_Dinter](#): > > Or is there some sort of online summary what I can look for? Well, just see/learn how JavaScript expressions work. And see the BLL app settings (and there links) for info on the included modules and methods. Where other properties exists, like in the AVD field reflections, those properties are shown in the popup infobutton next to the field, as examples, `$value` and `$values`. Now, in my answer > [@Arie\_J\_Godschalk](#): > > $value ? ‘Off course’ : ‘off course not’ Correction, **technicly** better should have been `$value === true ? 'Off course' : 'off course not'` That is just a basic javascript expression returning based on the value of the first object, in this case the variable containing the value, and if `true` (or “filled” with a object or value other than `undefined`, `null`, `0` or `false`) it will display the first given value after the questionmark, if it is an `undefined`, `null`, `0` or `false` it will return the last value, the one after the `:`. So, for example, if you want a button for a dimmer, that will be On if the dimmer is 1% or more, you could create a buttonfield with on/off, and use this Javascript expression: `$value > 0.00 ? true : false`. Or if you want to create a Sensor Textfield for a dimmertext: `$value == 1.00 ? 'Full on' : $value > 0.50 ? 'Half on' : $value > 0.00 ? 'Low on' : 'Off'` Also, everything know to the javascript engine on Homey, like the default `Date` object or the default `Math`, is available. Basicly everything thats available in HomeyScript, is available in BLL expressions, except the added stuff in HS like `Homey` or the tag stuff. Here is a site about JavaScript, and explaines, among other things, the Primitive Expressions. It’s perhaps a bit advanced or deep, but contains some good info and enough “images”/examples, that might trigger creative solutions or ideas. ![Screenshot_20240106_203734_Edge](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/8/f8f6a82e22552870da6efc1d017be4dabc38c407.jpeg) [Expressions and Operators - JavaScript: The Definitive Guide, 7th Edition [Book]](https://www.oreilly.com/library/view/javascript-the-definitive/9781491952016/ch04.html#:~:text=The%20simplest%20expressions%2C%20known%20as,language%20keywords%2C%20and%20variable%20references). ---

Is it still an bug causing problems for you/the app since the custom lists submitted all the way back from october still haven’t made their way into the experimental release? 🤔 ---

Indeed, sorry about that m8. I have thursday planned to furture update the homey-api dependency or to build workarounds to be able to release the testversion. ---

Hi @Arie_J_Godschalk , I have issues that are possibly related to short free memory issues of my Homey 2023? When I look at my apps using memory there are a few that go higher than all the others. Device capabilities and Better logic are going up to 91 mb for Device capabilities and 77 mb for Better logic. Not sure if this is normal for your apps but when I disable them and enable them again they both use about 20 mb less memory. After 30 minutes I see Device capabilities go back to around 85 mb. I have 55 AVD’s doing all kind of things with better logic and chronograph so maybe I ask to much of the app and my Homey? There is no way of disabling AVD’s to see whitch ones are responsible. I know I can create a TEF, delete them and import them again but that is not the most friendly way. Is there anything else I can do to let Device capabilities and Better logic use lees memory? After disabling Device capabilities and BLL ![Capture_1091](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/2/c2177ac272d5dfd02d46a4dc607d45001c63ac10.jpeg) 30 minutes later ![Capture_1093](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/4/642d8cb2877c26d7b3e8cc0ce499dff00fb23a44.jpeg) ![Capture_1094](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/b/8bebf89d8295ec6d14602ecd9d56c649ca331da7.jpeg) ![Capture_1095](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/f/5f2cc5a9ae829cac9bb7e1a1b999f7e24bd8a6d6.jpeg) BLL ca5f473b-cf07-425e-8b7a-cc85eaa5bdaa DC 509b621b-5f23-4e24-b3c6-128d07f62bdb Thanks. ---
