(whoops, I think I only sent my reply to Grant, sorry if this is a
dupe for the list.)
Hi Grant, Hi Antoni,
I had exactly the same question Antoni, and your answer Grant is
excellent. Thank you both very much.
The "off grid" part, will need a good battery, small solar panel,
sealed case of some type.
Once you know the power draw of the device, you can calculate the rest.
Anyone know if an "electric sheep fence" unit would be enough for a
few days of no sun operation? Those come in nice units with small
solar panel (40W?) battery, charge controller sealed for outdoor use
and are widely available at farm stores, no electronic skills needed,
but probably around 100 euros is my guess.
Good luck to all of us, and welcome Antoni! Please keep us updated on
your progress, a lot of people learn.
Best wishes, and stay safe.
Respectfully
Blake

Hello Antoni,
We have a list of supported development boards on our wiki
https://github.com/sudomesh/disaster-radio/wiki/Devices--&-Hardware
The best board to use right now is the LILYGO TTGO v2, which you can find on ali express
https://www.aliexpress.com/item/4000396836096.html
The TTGO can operate at 868Mhz, which is what I believe is the correct frequency for the
EU, but someone who knows more can correct me.
If you order the exact link I provided, the board should arrive pre-flashed with the
disaster radio firmware, though it will be an old version, so it may be best for you to
learn to flash them yourself, especially if you plan on deploying a lot of them.
Also, you gave me an idea to allow configuration of the LoRa frequency through the
console or web gui. I'm going to open an issue for this right now,
Thanks and let me know if there are any other question we can answer,
-grant

Hello,
I'm not electronic man. I would like to start using disaster radio.
What I must buy, I need offgrid and full autonomic device.
I live in Poland. Which device is good for my country? Which band? etc.
Thanks
Antoni
