How about an internet-connected, battery-operated, DIY weather station that costs less than $30? Sounds impossible? It is very much possible with a LILYGO T5 ESP32 board with a 4,7" e-paper display and OMW Weather Display open source project. All you have to do is to edit one file with WiFi credentials and location, compile it with Arduino and flash it to the ESP32.

Hello Pawel, I am currently testing the board. I still have a problem: According to the program, the wakeup time is set to 07:00 (int WakeupHour = 8; // Wakeup after 07:00 to save battery power). However, the board only switches from 11:00 p.m. to 8:00 a.m. at 8:00 a.m. No Wakeup at 07:00 .Do I have to change something else in the settings? Many greetings

This looks GREAT! Excellent video, ty! I have a unique system need for a super low-power self-reading weather station in a remotely placed camera housing, it cannot have any external communication & must be fully self sufficient. I love the ePaper for low power draw, I need the computer to read an EXTERNAL (outside the camera housing via wires) thermometer & hygrometer readings (every 10-20 seconds?) to calculate the very accurate dew point. I then need the computer to read a separate INTERNAL (Inside the camera housing) thermometer, and then I need the computer to control a relay that sends 3A-4A 12V to my internal heat strips to turn them ON & OFF so that my glass window remains "5 degrees" above the current dew point. I need to be able to adjust the "Degrees above Dew point" to fine tune the system for various conditions & locations. I'd also love to be able to control the time of day or night that the system is allowed to heat my window. I am trying to prolong the life of my battery as long as possible as I will not be able to even go check on the camera for days or weeks at a time. I'd like to eventually extend this to months. Any advice? tyvm

A super interesting project after I have seen your video I had directly order the board. First I installed version 2.5 and it runs without any problems then I wanted to upgrade to your version. But after the message from arduino ide: leaving hard resetting via RTS pin. Nothing happens. Do you have any idear where the problem is?

What is the sleep power consumption of this board? I need it to last as long as possible on a battery. I hope just a few micro amps

If I could connect this to a sim-card enabled weather station I place at my favourite flying spot, this would save me many waster journeys (not enough wind, wrong direction of wind etc)! Are you aware of any such projects?

Hello PS After Hour, you're right. It really is a great board. I now have it in a case and it's on my desk. I configured it to my city "Berlin, Germany". But my problem is that there is daylight saving time in Europe. I.e. the displayed time is currently one hour behind. In the winter she would walk properly again. My question: Where can I put the time forward by 1 hour? Thank you for your recommendation. I look forward to your early reply.

Interesting, I have it running 120km from you in Stettin, Poland and it switches times perfectly. Are you sure you sent correct time zone ? I have this const char* Timezone = "GMT0BST,M3.5.0/01,M10.5.0/02";

@uengel5755 Рік тому
@@PSAfterHours Hello Pawel, this setting for the time zone did not fit. I have now but via the link in the lib owm_credentials.h found the right setting: CET-1CEST,M3.5.0,M10.5.0/3 It works great now. Many greetings

Hello Pavel, I also have to notice that sometimes the board only wakes up from the hourly sleep phase after a reset. The time display is currently at 6:00 p.m., although it is already 8:49 p.m. Apparently this hourly rhythm is not reliable. CanI change something there? Greetings Ulli
@PSAfterHours

Maybe they changed something in the code. Mine wakes up and refreshes no problem all the time

Hello, great project that I would like to replicate. I just ordered the board. Unfortunately I get the following error when compiling: "C:\Users\uengel\Documents\Arduino\libraries\LilyGo-EPD47-master\src mt_pulse.c:9:24: fatal error: hal/rmt_ll.h: No such file or directory exit status 1 Error compiling for board ESP32 Dev Module.

ugh another arduino, you guys need to make the leap an move off arduino. the ide AWWFULLL. much less than having to build and export... I know you feel safe, but if you just make the jump to something like micropython you will do yourself and the makerspace so much powerful.
