Bon vol à toi l’ami 😎

Hi all

I just got my first meshtastic device a rak wisblock and im eager to get started building a network.

However I have no experience with radios and only limited experience with electronics and programming.

My plan is to build a network spanning from my place of work (Kalundborg, Denmark) to my home (Høng, Denmark) and on towards my mom's home (Skælskør, Denmark)

I want the repeaters to be equipped with some environmental sensors (temp, humidity, air quality, ect) which seems to be easy enough, but i also would like them to have a radiation sensor (incase the worst happens) is that possible?

The main use of the network would be environmental data collection and emergency planning/communication

How many repeaters should I expect to install?

What kind of antenna would be best?

And do I go with meshtastic or something else? (Not sure this question is allowed but im not sure where else to ask)

Any tips, tricks, warnings or feedback is more then welcome!

😁

Hi!

I wrote a tutorial explaining how to configure the Detection Sensor module and some practical use cases.

I struggled to find clear documentation, so I documented everything I learned.

I'd appreciate any feedback or corrections.

Bought a few of these for an upcoming festival with friends. This was the first card-sized Meshtastic node I've seen with a built-in compass, GNSS AND a screen in this format.

Quick take: Compass is ok if held flat and calibrated, display is good to read (but with a little ghosting), size and weight are really nice, GNSS seems fine but accuracy still TBD (will check properly soon), while it does not feel cheap - the production quality is not the best. The buttons are really hard to press plus the plastic coating on the buttons is coming off and on one of our 6 nodes the display is a bit tilted.(Not much but enough to trigger my inner monk) Can't say much about battery size but in the last 24h I lost 32% while connected constantly.

I paid 35$ and still think it's a great device for the price which might need some tweaks. :)

Wrote a more detailed blog post with pictures if you're interested: https://knoten.eu/heltec-meshnode-t1-first-look/

I noticed that the Meshnode T1 includes an accelerometer but I can't figure out from the schematics which GPIO pin should I select in the app. Thank you

Is there a way to have Meshtastic connected to ATAC and be able to message on long fast (what most people are using here in Albuquerque).

Hello everyone! I am working on mounting a node to my toolbox in my truck. I will not have a backup battery because I live in AZ and it gets too hot to leave a LiPo in the sun. My plan is to wire it from an Aux fuse box (including a relay) with a buck converter (12v to 5v). I will weld a mount base to the box.

The plan is to use a 12-20inch antenna while daily driving. While moving slow on desert roads, I'm flirting with 2 5ft fiberglass/ pvc pipes to act as a pole to run Coax cable to effectively increase the antenna from 12 inches to 5ft or 10ft.

I'm looking for help with some of the parts. My goal is to withstand AZ heat, have GPS, and have an effective LOS/ elevation. If anyone recommendations regarding parts or if anyone has a setup they'd like to share that would be much appreciated!

Hi, I'm new here.

I just received two Heltec V4 kits, to flash them successfully; they communicate with each other, but the range seems quite poor. I'm in the city center and only managed to exchange messages over a maximum distance of about 50 meters—with one node connected to my phone outdoors and the other at my apartment window. Here are the values I get when running traceroutes with the devices side-by-side. Is this normal? I powered up the first one without attaching the antenna and worry I might have damaged it; unfortunately, I don't know which one it was... but the mesures seem similar. Should I replace the antenna? Can you recommend others for portable use? Thanks.

I'd like to be able to communicate with a friend who lives 500 meters away. I'm in France, so I'm using the 868 MHz band.

Thanks!!

I have a Wio Tracker that I bought a couple weeks ago and was working perfectly. I'm not sure if I did something or not, but about a week ago it starting showing "0" online nodes. I know for a fact there are other nodes online nearby. I feel like I've tried everything to remedy the problem. I have wiped the firmware twice and re-installed the firmware and it makes no difference. My setting are correct. Role: Client, US/LongFast Freq 906.875 ver. 2.7.26, 11 Sats. 0 online. I used the python cli for a factory reset also. Not sure what else to do. Any help is appreciated!

Bought a Heltec v3. Does anyone know the where abouts of an idiots how to manual. Looking at how to set it up.

Has anyone had experience of the LilyGo T-watch S3 Plus or similar?

I have been looking at getting something like this for my teenage son, as a project for us to work on together.

I have been looking to get him into LoRa communications and as he doesn’t currently own or use a watch thought this might be the best idea, rather than him having to worry about carrying (and no doubt losing) a secondary Mesh comms device.

Are these any good as a personal device and do they have sufficient power in their internal antenna? I have seen them in AliExpress for around £45, so worth a punt.
