Ok, I think I found the error. Can you please check again teh HomeyScript result? Is there really a space in Unit string? ![grafik](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/6/a627c4d99211fa6484f890d016238f138d7cfc48.png) The unit should be `'%'` without spaces between. It seems itā€™s a bug in Athoms capability definition. Donā€™t know if the documentation is representing the code. I will ask on Slack. ![grafik](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/4/24289171b43a9ee26917a4b256da4b2860a33d3c.png) This should only affect norwegian users because the space is only existing in norwegian unit. ---

New **test version 4.1.5** : - Added workaround for wrong dim unit (norwegian). @SnorreDjupedal FYI. Can you please check if the dim capability is working now with a correct range 0ā€¦100? I added a workaround to check for dim capability in addition to unit. ---

Hello, @RonnyW is there already a workaround for the issue of duplicate names MQTT name changes in Home Assistant 2024.2.x the problem is documented here: [MQTT Name changes in Home Assistant 2024.2.0 Ā· Issue #99 Ā· harriedegroot/nl.hdg.mqtt Ā· GitHub](https://github.com/harriedegroot/nl.hdg.mqtt/issues/99) I havenā€™t found anything about this yet. It would be very time-consuming to change the EntitƤts ID in the HA manually. ---

Hi @RonnyW , there is still a display problem with the buttons when creating an MQTT device. The buttons are sometimes not visible.

I forwared this error to Athom via Slack. For now, the dim capability is fixed for this app, but there are some other capabilities having a space in their unit. Letā€™s hope Athom will fix it soon. ---

@RonnyW Hi Ronny, I installed the new homey firmware 12.0.1-rc.8 and see crashes of the mqtt hub community edition appā€¦ 12.0.1-rc.8 app =\> 4.1.4 send message delay configured to 10 ms (like in the stable homey firmware before) Do you see similar issues? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/6/565e3a1622e81595f6f731f3e02fd5d1eb5f39bc.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/3/63cd7e03db14ec7b466b77d4af88bacf4f46ace2.png) I restarted the app after several crashesā€¦ and it works nowā€¦ but with very high memory usageā€¦ installed version 4.1.8 (test) now - same behaviour ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/5/750f718d6fe9f8bc272fc305a5b582d0297e9257.png) ---

I havenā€™t changed the main logic. Butit can be CPU or RAM related. With 4.1 the CPU/RAM alert events should finally work. Then I can add a flow trigger to get informed about such events - to know the reason. And for me itā€™s also working with 80MB (HP23) ![Screenshot_20240815_153951_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/d/4dd2888aebe3004e56186f2508d3529b06462cbb.jpeg) ---

I changed the message delay to 25 ms - looks better nowā€¦ but the app consumes lots of memory - maybe you will find the reason for this in near future šŸ˜‰ ---

No way. Itā€™s the WebAPI and the amount of devices/messages. All apps are consulting more memory on a HP23 than on a HP19. For me, the Athom limits are a way too strict for such messaging apps. Itā€™s similar for HA app. But there the WebAPI is not used which saves some MB. ---

New **test version 4.2.0** : - Added **flow trigger** for **memory/CPU warnings**. - Added setting to **choose a capability naming variant** (old: device name + capability name; new: capability name) to get compatible with **HomeAssistant** discovery since version **2023.8** - Added r **estart flow action** and **restart button in app settings view**. This restarts the whole Hub including device registry, HA discovery and device/state broadcast. You can now use this flow to update HA discovery after Homey restart. An app restart is not needed. - Changed settings view: Instead of saving settings and starting a broadcast for every change (checkboxes, input fields), there is a **new ā€œSave settingsā€ button** now to save settings and restart the Hub (to broadcast all states incl. HA discovery and device registry). Some settings needed an app restart before to take effect which should not happen now with a complete sync after saving settings. The app flow action: ![grafik](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/0/e0e1b21a35b22273799cc48185703cfa23f24b18.png) Settings view. - Broadcast button with light blue progress bar. - New button ā€œRestart Hubā€ - New button ā€œSave settingsā€ - ![grafik](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/d/0d8226bc050f4300feb2997ab464b821377f1aee.png) @L_Gru : FYI, The capability name can now be changed to capability name only.
