Nice, enjoy it. If you have any questions let me know. To get the best range make sure to replace the antenna, Here are some recommended by Meshtastic Team. https://adrelien.com/best-antenna-for-meshtastic/
https://meshtastic.org/docs/configuration/radio/lora/ You can find all the details here, For your country you are only allowed 915.0 - 928.0
from the part list, you only need Lora and esp. that can get you up and running as for assembly it takes only 10 mins max. But again there is a market for ready products and market for DIY. I had some esp32 with Lora from other projects and used it, you might not have it. But the heltec is also a good cheap starting point. As for the ID well, actually most of the time your government asks for ID number to tax you if needed. But you are free to order from Amazon as well. You can find amazon links on the website if you wish, I won’t be sharing them here not to make anyone angry
