Hi,
I developed a little program for use on the Wemos D1 Mini Pro (an Arduino sibling) or on the NodeMCU unit.

The result being a very compact device for DDNS use

I built some units using an empty LEDLamp housing as enclosure, that at regular intervals update the IP address of an Dynu domainname. (see picture)

When you find this interesting enough for your users I am willing to share the program with you and/or the community.

Looking forward to hear from you....

Cool!

I just started to search to see if it had been done already. Do you mind sharing the sketch?

Thanks!

Hi Zeedan,

Attached please find the arduino sketch.
It should work with any esp8266 based Arduino compatible.
Please remember to install the esp8266 related boards and libraries prior to compiling and upoading?

Looking forward to your results?
Best regards,
Joep

Thanks! Since the administrators didn't allow me to post my message until it was reviewed, and I didn't know how long that would take, I went to github and found that someone had uploaded a universal version that could be used for several DDNS providers, and the libraries are included.

How long of an uptime have you had? I see that you have the built in LED blink to make sure it is running and didn't lock up. I'm going to blend it into my weatherstation sketch for the same reason.
