Yes, this should be fixed in the Awair app. Are the two other fixes working now? ---

Hi @RonnyW My MQTT Hub v4.5.4 crashes almost every day on my Early 2019 Homey Pro and i have to restart ist again. The LOG is 4781ce0c-5721-4a81-9e7e-e088fcc06cf9 Maybe you can find out what is going on. ---

It’s a system error. Maximum call stack size exceeded Perhaps the app gets too many messages from your broker resulting in too many parallel processes/calls. There is not much I can do 🤷‍♂️ ---

Hi, first of all, thanks for keeping this app going. I only recently found out this one replaced the older 3.x version. What I’ve found in this 4.x version is that deleted devices are retained. Perhaps I’m overlooking something. Whilst developing my own app I’m creating/deleting/recreating just one exactly the same device multiple times, the list of devices in MQTT-hub keeps growing, continuously adding this device again and again. Can I prune this list without removing and reinstalling MQTT-hub? ---

Hi Ronny, After installing the test version v4.6.0: It turns out my 2 Trust Smart Home lights now got published as lawn mower instead of light 😜 > ![Screenshot_20260729_222847_Home Assistant](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/3/b3052181f990a1feb2a123babacf1b89542e279a.jpeg) Installing the stable MQTT Hub version solves it; it is shown as ‘light’ again, and ‘lawn\_mower’ became unknown: ![Screenshot_20260729_225941_Home Assistant](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/0/70bf0ca4096a3bf568827316a8b89e3ece82cbb4.jpeg) ![Screenshot_20260729_230012_Home Assistant](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/7/478c36cca84393d38bb8ba17d1beb1f58e28d202.jpeg) If there’s anything you want me to test, just shout. ---

Wow, that’s not as expected 😅 It should only export a lawn mower if device class is “lawnmower” or capability “mower\_state” exists. Can you please check the Homey device details (class, capabilities)? ---

**Edit** There’s more devices converted to lawn\_mower, @RonnyW . _The common factor is_ ‘Class: Socket’ Maybe this rings a bell? ![15013](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/5/c5ea56fd420b3cb515c81236c11fc7b10a8ce383.jpeg) Device overview of one of the sensor onoff devices (being an AVD of Device Capabilities app) ![15017](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/d/6dbd8382b2fd3f4f4dc6157ad36c38bf7a610de4.jpeg) The lamp mentioned below actually is a socket with dim functionality (original post) Ha I can imagine 😊 Here’s the lamp details ![Screenshot_20260729_235903_Ecosia](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/b/bb0319373469e6253f48a92b5890b44911095e4b.jpeg) ---

I haven’t actively used MQTT for a while, but there’s a nice new iOS app (in beta) for creating widgets: > **[Canvases - Build your own widgets in a visual editor](https://canvases.app)** > > Canvases gives you the pieces to build custom widgets in a visual editor, then keep them up to date automatically with Shortcuts. It does not support MQTT directly, but another iOS app does offer data via Shortcuts: > **[GitHub - philipparndt/mqtt-analyzer](https://github.com/philipparndt/mqtt-analyzer)** > > Contribute to philipparndt/mqtt-analyzer development by creating an account on GitHub. So I want to experiment with this, but somehow I’m getting old/stale data? For example total gas used reports 8xxx, while it’s 9yyy. What could be wrong? How to debug/fix this? ([mosquitto\_sub](https://mosquitto.org/man/mosquitto_sub-1.html) on Ubuntu reports the same wrong values; that’s why I think my issue is on the hub side) [Previous page](https://community.homey.app/t/app-pro-mqtt-hub-community-version/113463.md?page=14)
