Make sure that the module configuration in the Tasmota firmware matches the driver that you’re using to add the device to Homey. ---

It looks like you’re using a non-standard MQTT topic setting. The “full topic” setting should be the default value: `%prefix%/%topic%/` The “topic” setting can be chosen to your liking. For example, I have this configuration for my Sonoff RF Bridge: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/2/2e3f00c16cc361be0b76c52a94844af1f90a1ffd.png) ---

its working like a charm appreciated. it was the non-standard MQTT topic setting issue. much appreciated regards ---

I am reading this topic but it doesn’t solve my problem although it looks I am running into the same kind of issue: When I try to install the sonoff basic(tosmota) from the equipment ( apparaat toevoegen) i get a screen asking for the MQTT broker hostname/IP Her i fill the homey IP in ( in my case 192.268.20.11) the next is MQTTbroker port (1883) pre-filled in and the I am asked to fille in the MQTT borker username and password (optional). I don’t fille in these as they are optional pressing “next step” results in the message "“MQTT connectie kon niet worden gemaakt” I have a sonoff basic flashed with tamota 12.3.1 below the infomatio from the sonoff: ### Sonoff Basic ## Tasmota | Program Version | 12.3.1(tasmota) | | --- | --- | | Build Date & Time | 2022-12-16T10:28:17 | | Core/SDK Version | 2\_7\_4\_9/2.2.2-dev(38a443e) | | Uptime | 0T00:03:24 | | Flash Write Count | 22 at 0xFA000 | | Boot Count | 8 | | Restart Reason | Software/System restart | | Friendly Name 1 | sonoff01 | | | | | AP1 SSId (RSSI) | jtb (88%, -56 dBm) 11n | | Hostname | sonoff01-7567 | | MAC Address | 4C:EB:D6:B7:3D:8F | | IP Address (wifi) | 192.168.20.29 | | Gateway | 192.168.20.254 | | Subnet Mask | 255.255.255.0 | | DNS Server1 | 8.8.8.8 | | DNS Server2 | 192.168.20.254 | | | | | HTTP API | Enabled | | | | | MQTT Host | 192.168.20.11 | | MQTT Port | 1883 | | MQTT User | sonoff01 | | MQTT Client | sonoff01 | | MQTT Topic | sonoff01 | | MQTT Group Topic 1 | cmnd/tasmotas/ | | MQTT Full Topic | cmnd/sonoff01/ | | MQTT Fallback Topic | cmnd/sonoff01\_fb/ | | MQTT No Retain | Disabled | | | | | Emulation | None | | | | | ESP Chip Id | 12008847 (ESP8285N08) | | Flash Chip Id | 0x14325E (DOUT) | | Flash Size | 1024 KB | | Program Flash Size | 1024 KB | | Program Size | 629 KB | | Free Program Space | 372 KB | | Free Memory | 26.4 KB | * * * [Tasmota 12.3.1 by Theo Arends](https://bit.ly/tasmota) Does anybody know what I am doing wrong? ---

I did not chek the line: authenticatie van gebruikers aanzetten ( Wordt niet aangeraden) should I do that? ---

I assume you mean “uitzetten”. Whether you should do that or not is a personal preference. But if you don’t want to disable it, you need to create a user/password combination and configure your device to use it. ---

OK, I just checked the checkbok in the broker. Now I seem to come a bit further: but I now come to a white screen with a turning Wheel It is asking to (soft) reboot the sonoff ,which I did. and then it says “no new equipment found” ---

So you’re using the [Sonoff app](https://homey.app/nl-nl/app/name.klep.sonoff/Sonoff/)? That app is deprecated (won’t be developed any further) and only works with Tasmota versions 6 and lower. You’re going to have better luck with the [Tasmota MQTT app](https://homey.app/nl-nl/app/com.paveld.tasmota/Tasmota-MQTT/). ---

Ok, This is actually working.! Thank you so much. This took me three days of experimenting! [Previous page](https://community.homey.app/t/cant-get-mqtt-broker-app-to-run/9985.md?page=1)
