@Phuturist Altering the payload values is not possible (yet). Adding value `templates` could be a nice addition to the functionality of the MQTT Device. For now, you’ve got a few options: 1. Alter the device settings accepting true/false (if possible) 2. Use a Virtual device operating on flow cards (from MQTT Client) to do it manually… 3. Use NodeRed to convert the payload 4. Create a Pull Request/Wait for someone to extend the functionality of the MQTT Device 5. other…? ---

I’m getting ready to dive in this weekend. This is exactly what Homey has been missing for quite some time now. ---

I’m trying to grasp some things. I want to control Heimdall using MQTT gateway. Setting the surveillance mode to disarmed, armed or partially\_armed works fine but I cant seem to set the alarm-heimdall capability to false after it was triggered. Obvisouly both are custom capabilities and their only difference is that one is enum and the other is a boolean. Is this just a matter of support somewhere inside the MQTT hub (which I would need to dig in) or am I overlooking something else. And another issue I ran into. I have a Xiaomi Mi Robot vacuum which has the onoff capability. When setting this to true I can see the topic set=true in MQTT explorer but the capability onoff does not actually change to true. I also dont quite understand what is going on here. Could someone explain what is going on here, I’m still quite new to MQTT. ---

@Phuturist No need to create a GitHub issue. It’s probably an Homey issue… I encountered equal error messages when a ‘broadcast’ was running. Mostly it succeeded when I tried later. I already did some debugging. The timeouts are not from the MQTT save device settings logic. Homey is not responding to the request (in time) for unknown reason. ---

Hi @HarriedeGroot. Just connected a Philips Dimmer / Switch, but I don’t receive MQTT messages when I press buttons. The device is listed in “Devices” section of the App, and all the other devices (I didn’t use smart switches before) work just fine. If I create a workflow in Homey the switch works great. Is it supposed to work? MQTT Hub: 2.1.9 / 2.2.5 Homey: 2.1.1 ---

MQTT Explorer shows this: ▼hue-dimmer-switch $type = sensor $name = Hue dimmer switch The “type” is “sensor” for some reason, is that correct? ---

The timeouts are not from the MQTT save device settings logic. Homey is not responding to the request (in time) for unknown reason. Weird stuff … I tried numerous of times at different times and states (after app reboots, after Homey reboots) but keep bumping into this error. It’s not gonna fly for me I’m afraid. ---

According to a source code the device doesn’t provide any capabilities. I checked other remote dimmers and found the same issue. Do you have any ideas? It looks like all these devices should expose something more useful than Flow Triggers. ---

It may be an issue with ‘button’ type devices as they don’t publish their ‘transient’ state to MQTT either. ---
