Someone asked a similar question in the forum a few days ago.  
Here's my response about using a Rules Set in ESP Easy running using a Wemos D1 Mini.

> I agree with what @ristomatti said... I installed Mosquitto on Node-RED and it ran 'straight-out-of-the-box'. In the above example my Wemos will publish to a topic called... node92/dht11/temperature So all you need to do in Node-RED is use one of the core nodes MQTT-In with a subscribe topic of... node92/dht11/# Hope this helps. I can post some sample NR flows if you get stuck.

As Colin said... you don't need to keep subscribing.
