no problem :)

I am so sorry for the late response, https://s.click.aliexpress.com/e/_DF5Ry0R First, this is an affiliate link, Second I have not tested it, I will actually order it and test it with NRF52, it is worth it now. I will try to find a better board with Ipex support test it and link it on my website

I mean you kinda of looking at from the wrong way, In the company I work for, it was a time saver. A department of engineers in embedded systems can upload some measurements then another department can quicky run some questions to write the findings for a customer. They both don’t know anything about SQL and ti is even faster than the tool we built for them. Since they have to filter through 1TB of data. Yes it needs a lot of optimization to get it perfect.

But I mentioned llama, which is self hosted

No idea what eli5 means

Maybe I misunderstood you, but how can you use existing ones without carrying a node?

Hope you liked the information.

Hmm, yeah. Well for me I am not an expert guy. I am looking to get license free comm device, I see Meshtastic with text comms and PMR with voice.

Perfect I got also GIzont they are pretty good, Enjoy meshing

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

Like what spam? I am not selling anything nor I am asking for your information

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

Well, Sorry to bother you then. Nothing else I can do

It does actually, You can see the parts list at the top of the blog.

So the frequencies matter a bit. I run on 433mhz but I bet lora is good enough even at the US 915. So yeah it can even go further. Meshtastic 254KM was done on US 915. https://meshtastic.org/docs/overview/range-tests/

I can’t tell you how right you are. I used it in power outages" Sometimes cell signal goes down " where you look at your phone and realize ok well I have no backup plan.

I also tried it when I was skiing in the winter. It was cool. I have GPS on my nodes. and I can tell where my friend is, tried also the telemetry sensor to tell the ALT but since it only tells the pressure it is not intuitive. You can probably tell if the person is up or down
