I have Homey PRO and would like to control heating manifold using 2 Sonoff 4CH (Tasmota) relays. I’ve problem with adding Sonoff 4CH devices to Homey. Sonoff app is installed. MQTT broker is installed and configured (Broker is running). Adding device I get error “MQTT connection unsuccessful” . Could anybody please help me with that? ![Tasmota - Information](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/6/56318f4b83f80838a665445a493046cd60a1b08f.png) Console: 00:00:00 CFG: Loaded from flash at FA, Count 96 00:00:00 Project tasmota Tasmota Version 8.2.0(tasmota)-STAGE 00:00:00 WIF: Connecting to AP1 Master ruuter in mode 11N as %prefix%/%topic%/-3448… 00:00:07 WIF: Connected 00:00:07 HTP: Web server active on %prefix%/%topic%/-3448 with IP address 192.168.31.171 20:53:01 RSL: tele/%prefix%/%topic%/INFO1 = {“Module”:“Sonoff 4CH”,“Version”:“8.2.0(tasmota)”,“FallbackTopic”:“cmnd/DVES\_C70D78\_fb/”,“GroupTopic”:“cmnd/tasmotas/”} 20:53:01 RSL: tele/%prefix%/%topic%/INFO2 = {“WebServerMode”:“Admin”,“Hostname”:"%prefix%/%topic%/-3448",“IPAddress”:“192.168.31.171”} 20:53:01 RSL: tele/%prefix%/%topic%/INFO3 = {“RestartReason”:“Software/System restart”} 20:53:01 RSL: stat/%prefix%/%topic%/RESULT = {“POWER1”:“ON”} 20:53:01 RSL: stat/%prefix%/%topic%/POWER1 = ON 20:53:01 RSL: stat/%prefix%/%topic%/RESULT = {“POWER2”:“OFF”} 20:53:01 RSL: stat/%prefix%/%topic%/POWER2 = OFF 20:53:01 RSL: stat/%prefix%/%topic%/RESULT = {“POWER3”:“OFF”} 20:53:01 RSL: stat/%prefix%/%topic%/POWER3 = OFF 20:53:01 RSL: stat/%prefix%/%topic%/RESULT = {“POWER4”:“OFF”} 20:53:01 RSL: stat/%prefix%/%topic%/POWER4 = OFF 20:53:05 RSL: tele/%prefix%/%topic%/STATE = {“Time”:“2020-04-13T20:53:05”,“Uptime”:“0T00:00:14”,“UptimeSec”:14,“Heap”:27,“SleepMode”:“Dynamic”,“Sleep”:50,“LoadAvg”:19,“MqttCount”:0,“POWER1”:“ON”,“POWER2”:“OFF”,“POWER3”:“OFF”,“POWER4”:“OFF”,“Wifi”:{“AP”:1,“SSId”:“Master ruuter”,“BSSId”:“EC:41:18:01:03:51”,“Channel”:9,“RSSI”:100,“Signal”:-39,“LinkCount”:1,“Downtime”:“0T00:00:08”}} 20:58:05 RSL: tele/%prefix%/%topic%/STATE = {“Time”:“2020-04-13T20:58:05”,“Uptime”:“0T00:05:14”,“UptimeSec”:314,“Heap”:26,“SleepMode”:“Dynamic”,“Sleep”:50,“LoadAvg”:19,“MqttCount”:0,“POWER1”:“ON”,“POWER2”:“OFF”,“POWER3”:“OFF”,“POWER4”:“OFF”,“Wifi”:{“AP”:1,“SSId”:“Master ruuter”,“BSSId”:“EC:41:18:01:03:51”,“Channel”:9,“RSSI”:100,“Signal”:-41,“LinkCount”:1,“Downtime”:“0T00:00:08”}} 21:02:51 APP: Serial logging disabled 21:03:05 RSL: tele/%prefix%/%topic%/STATE = {“Time”:“2020-04-13T21:03:05”,“Uptime”:“0T00:10:14”,“UptimeSec”:614,“Heap”:26,“SleepMode”:“Dynamic”,“Sleep”:50,“LoadAvg”:19,“MqttCount”:0,“POWER1”:“ON”,“POWER2”:“OFF”,“POWER3”:“OFF”,“POWER4”:“OFF”,“Wifi”:{“AP”:1,“SSId”:“Master ruuter”,“BSSId”:“EC:41:18:01:03:51”,“Channel”:9,“RSSI”:100,“Signal”:-40,“LinkCount”:1,“Downtime”:“0T00:00:08”}} 21:08:05 RSL: tele/%prefix%/%topic%/STATE = {“Time”:“2020-04-13T21:08:05”,“Uptime”:“0T00:15:14”,“UptimeSec”:914,“Heap”:26,“SleepMode”:“Dynamic”,“Sleep”:50,“LoadAvg”:19,“MqttCount”:0,“POWER1”:“ON”,“POWER2”:“OFF”,“POWER3”:“OFF”,“POWER4”:“OFF”,“Wifi”:{“AP”:1,“SSId”:“Master ruuter”,“BSSId”:“EC:41:18:01:03:51”,“Channel”:9,“RSSI”:100,“Signal”:-39,“LinkCount”:1,“Downtime”:“0T00:00:08”}} 21:09:19 RSL: stat/%prefix%/%topic%/RESULT = {“POWER3”:“ON”} 21:09:19 RSL: stat/%prefix%/%topic%/POWER3 = ON 21:09:21 RSL: stat/%prefix%/%topic%/RESULT = {“POWER3”:“OFF”} 21:09:21 RSL: stat/%prefix%/%topic%/POWER3 = OFF ---

If you run the broker on Homey, it’s Homey’s IP address. ---

Done. I add screenshot from console. Seems that is not working? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/d/ede5196405caabe0bef503ab79861b5955b50df0.png) ---

Correct. I believe “rc 5” means “incorrect credentials”, so check if your MQTT username and password are correct on both sides. ---

I double checked and credentials are same on both sides (Tasmota configuration and MQTT broker side - user and pass are correct). I re-inserted credentails and MQTT broker pop-up message says “No setting has been changed”. What else I can do? ---

Your topic is wrong, it should contain a (unique) name for the device (without spaces, slashes or percent signs). Something like “sonoff-4ch”. “Full Topic” is correct. ---
