Hi,, after fifteen months spent trying to learn how to use Arduino and ESp32 ( I'm an old newbie, 73 y old) I just subscribed a plan on Arduino IOT Cloud. I started with some very basic code just trying to collect data from a BME280 sensor and time from a RTC DS3231 ( since I was able with this mC…

Does an example sketch for the DS3231 work ?

if (! rtc.begin()) { Serial.println("Couldn't find RTC"); while (1); } else { // following line sets the RTC to the date & time this sketch was compiled rtc.adjust(DateTime(F(__DATE__), F(__TIME__))); } You need to stop resetting the RTC time whenever the sketch runs.

Hi, Thanks for your prompt answer When I use deepsleep with esp32 usually after compiling the sketch I comment out the line you point at so that when it awakes the correct time is displayed and I've used this also in this case but at no avail. I really don't know if in this case it's useful or no…

Hi, Thanks for your help. The code works just fine out of Arduino IOT Cloud. Probably I need to use NTP time as I've done with dataloggers when a reliable wifi was available but I'm afraid not to be able to adapt the code I used to IoT cloud Do you have any suggestion and/or any example I could …

Hi, Where you able to solve the issue? I have a similar problem. I built a clock that is connected to Arduino cloud and uses RTCZero. I know that this starts the internal clock of the Arduinon Nano 33IOT and will lag within some ours (it is running 20min behind in one day). For this reason I tried …

Hi, no I left aside Arduino IOT Cloud since I met several problems when trying to adapt my codes to the cloud. Furthermore I've found that this issue ( Arduino Cloud) still seems not so attractive to forumers as it is clearly demonstrated by the fact that several months have elapsed without any fu…

Thanks for your update. I found a solution for my cloud connected clock. It was running late 20 min after one day, so i thought I needed to add a RTC, but this was messing up my code. Apparently I only needed to add the line: TimeService.setSyncInterval(600); This syncs the time to keep on track. …

Hi, thx for your suggestion. I'll try it. Where did you find this way of solving the issue ?

[image] Arduino RTC does not stay in sync despite use of ArduinoCloud.getLocalTime(); UNO R4 WiFi Hi, I use an arduino R4 wifi to display messages on the led matrix. But every 6 messages, I want it to be used as a clock and request it to display the current time, which com…
