- Thu Nov 16, 2017 10:38 am #71891 Hi, guys,

I have a project with 3 esp 8266 nodeMCU v1. This is Alarm System. 1 module is a server and 2 modules are clients. To clients i join PIR sensor and they send the data to server. I want is for the server to show the number clients connects to him. If i turn on 1 client - server show me "Clients is - 1" etc. If for example 2 clients and i turn off 1 i want something that would show the correct amount. When i take this code viewtopic.php?f=32&t=5669 alternate (if i turn on show 2, turn off - turn on show me 3 and so on). Please help me I can donate
