Hi Sasa,
It’s important that the SD card is present and connected.
Put the log in this topic, we are going to check It.

Hi bongo,
I think you must follow this thread,
esp32 with w5500 constantly rebooting
and you must use a service like SendGrid

Hi,
you can check this to understand the basic constructor.

To manage interrupt you can find all information here at this link.

Hi all,
Finally you can find precompiled files and instruction on this article

I add you to Author role, now on this link you can create post upload image and so on.

When I have some time I’d like to help you to improve the weather station with web interface and other.

But first the article, where I’m going to study the solution 😉

I send you an email so you can grab my email address and if you need some help write directly to that.

Thanks Renzo

It’s very beautiful, would you like to write some articles about that on this site?
I’d like to create a section for this purpose.

Hi Eugenio,
The step up raise the voltage from 2v to 5v to a fixed 5v.

I think a good solution (I use this with 18650) is a step up like the one used here
Emergency power bank homemade

Now I find a little module that do recharge and step up to 5v, but I don’t tested yet

If I test It I’m going to inform you.

Hi Eugenio,
to get the best performance you must power the E22/E32 with 5v and a sufficient amperage.
If you use 3.3v you lost some kilometres.

Hi Andrew,
if you want exist the versione for WeMos D1 mini an esp8266.

Hi Eugenio,
in general for AUX I prefer to use RTC GPIO
ESP32 practical power saving: preserve gpio status, external and ULP wake up – 5

For M1 and M2 I exclude special pin like EN GPIO0 or similar for the tedious problem with initial state

But If you can use the pin of the shield, that are tested a lot.

Hi Andrew,
I think you are wrong, I have some versions of NodeMCU (esp8266) and the form factor isn’t the same of esp32 DOIT DEVKIT v1 as you can see in the photo.

Hi Andrew,
I can’t see your photo, read the note to the left to insert external image or upload a 512Kb image.

It’s strange It’s fit perfectly like you can see in the photo

Hi,
the fast answer is, no you can’t.
But if you change the library and reference an instance of pcf8575 you can try to manage via espander.

Hehe.. no problem Rudy
