#69011 Cost difference is about $5. Pi Zero W is $10, NodeMCU is $5-$8. Other costs are similar, case, PS, but Pi also needs SD card.

The point is, a complete Pi Zero W with case, PS, SD is about $25-$30. NodeMCU in a box with PS might be $15-$20. The savings isn't enough to justify all the things that ESP8266 lacks, performance, memory, OS, programming languages, debugger, stability.

I like ESP8266 and ESP32. For many things, they are an excellent choice. For an MQTT broker, not so much.
