I am working on IIOT related project in which I am using nodeMCU as a node devices and using pi as a server. But I found some problem with NodeMCU. Sometimes It does't work as expected. I have attached DHT11 and its sending data to Raspberry pi and I am using openhab to see the temperature but when I installed it. Its not giving me the live data. I need to restart it to get the current data from it to openhab. Kindly suggest the solution for this or I have to change my hardware?
