Wemos D1 r2 locking every 15 hours

I use a Wemos D1 r2 with DHT22 and BH1750 (lux) sensors which values i send to Domoticz using GET method.

I had my test setup running pretty stabile, so i've put it all together in a box, placed my sensors outside and guess what... i see it locking :? Even though it does work successful for about 15 hours, it stops every night for some reason.

I don't have a good indication of what's going on, i figured that it could be related to the Wifi signal, since it's in a different spot than where i tested before. Or otherwise could it be related to the sensors? I've soldered them to a 3m long (USB) cable.

Below is my (current) sketch, thanks for your ideas!

Code: Select all#include <DHT.h>
#include <ESP8266WiFi.h>
#include <BH1750.h>

// ========================= LED PIN ========================
#define LED_PIN D5 // Led pin

// ======================= DHT11 / 22 =======================
#define DHTPIN D3
#define DHTTYPE DHT22
DHT dht(DHTPIN, DHTTYPE);

// ==================== lightmeter BH1750 ===================
// BH1750 Light Sensor connection: VCC to 5v+ | GND to GND | SCL to pin SCL/D1 | SDA to pin SDA/D2 | ADD not used
BH1750 lightMeter;

// ========================== Wifi ==========================
const char* ssid      = "myssid";
const char* password  = "mypass";

// ============= Domoticz host address and port =============
const char* host = "192.168.2.100";     // NOTE: There should not be http:// before the address!!!
const int httpPort = 8080;

// =============== Domoticz devices to update ===============
int domoticz_temp_idx = 133;
int domoticz_hum_idx = 167;
int domoticz_lux_idx = 168;

// ==========================================================

Hi, check your router/Access point logs and see if it fails to renew its lease and gets kicked off the network. I had this problem and had to change some settings but can't remember what thet were.

;) good point, thanks! I did install a new router a couple of weeks ago, haven't had any problems though, but this might explain why it doesn't respond to a ping. I'll look into it!

Had another look into my ZTE router, i already set a static IP so it should have an infinity lease.
Then looking at my code again, let's say the wifi signal gets lost, how could i create a fall back? In other words, can i test my connection in every loop and re-connect in case it got lost? Would this be a good example?

:roll: being a newbie, does digitalWrite(2,1); initiate a reboot so that it will go through setup() again?
