Implementing MQTT for a building

Question

So, I want to implement MQTT architecture for a building. Around 1000+ nodes are communicating and interchanging data with broker. This communication is bilateral(data is subscribed & published as well). I want to know, can MQTT handle two way communication for 1000+ nodes? Is't it going to get any conflict? Also, we are using ESP8266 chip at node side.

Answer 1

I'm not really sure if its possible to answer this question, since no specific information regarding the situation you intend to deploy is given. But I'll try regardless. Hope its helpful. 

MQTT is a protocol not a solution, the size of the deployment entirely depends on the following:

• number of clients
• size of the messages being sent
• rate of message being sent
• type of broker (single instance/distributed cluster)
• type of network infrastructure involved

1000's of clients is nothing compared to some of the deployments from tech giants like Microsoft and IBM.

Your best bet is to build a test rig and test it to see how much resources your specific scenario can exploit.
