I had built this as custom setup for a friend, based on this 4 Channel Relay Board https://www.creatroninc.com/product/4-channel-5v-10a-dc-relay-module/?search_query=relay&results=40

I had flashed a stock nodemcu with son off-tasmota 6.5.0, and made these configuration changes.

1 - Under Configure MQTT, I set the full topic, to

%prefix%/%topic%-7360/

2 - Configure Module

Type 18 - Generic

D3 GPIO0 Button1	
TX GPIO1 Serial Out	
D4 GPIO2	
RX GPIO3 Serial In	
D2 GPIO4 --> Relay 2i
D1 GPIO5 --> Relay 1i	
D6 GPIO12 --> Relay 4i	
D7 GPIO13 Led1i	
D5 GPIO14 --> Relay 3i	
D8 GPIO15	
D0 GPIO16	

3 - In the console

Rule1 1
Rule1 on Mqtt#Disconnected do MqttHost 0 endon
PowerOnState 0
SetOption55 1

4 - On my mosquito server, created a file /etc/avahi/services/mosquitto.service

<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
 <name replace-wildcards="yes">Mosquitto MQTT server on %h</name>
  <service>
   <type>_mqtt._tcp</type>
   <port>1883</port>
   <txt-record>info=Publish, Publish! Read all about it! mqtt.org</txt-record>
  </service>

</service-group>
