Neat!

So how'd you do it?

What exactly are you powering with these 20mA?

This only one board Wemos D1 Mini + Sensor DHT21(AM2301)

My script:

// Init ESP8266
var ESP8266 = require("ESP8266");
//ESP8266.setLog(1);
//ESP8266.printLog();  
E.setClock(80);


// Init WiFi Networks
var wifi = require("Wifi");
wifi.setHostname("WemosD1mini");
wifi.connect("XXXX", {password:"XXXX"}, function(err){
  setTimeout(function(){
    console.log("connected? err=", err, "info=", wifi.getIP());
  },5000);
});
wifi.stopAP();
wifi.save();



var dht2 = function(){
  var dht = require("DHT22").connect(D14); // GPIO0
  dht.read(
    function(a){
      console.log("Temp is "+a.temp.toString()+" and RH is "+a.rh.toString());
      var newDht = a.temp.toString()+","+a.rh.toString();
      postToServer(newDht);
  });
  return true;
};


// Send Every 5 min
setInterval(function() {

  setTimeout(function () {
    dht2();
  }, 20);
  
}, 300000);

setDeepSleep(1);

function postToServer(data){
  var options = {
    host: 'XXXXX',
    port: '80',
    path:'/event',
    method:'POST',
    headers: {
      "Content-Type":"application/json",
      "Content-Length":data.length 
    }
  };

  require("http").request(options, function(res){
    var d = "";
    res.on('data', function(data) { d+= data; });
    res.on('close', function(data) {
      console.log("Closed: "+d);
    });
  }).end(data);
}
