Meshtastic

This is a generic metrics post to leverage a spare ESP32 meshtastic node to ingest metrics into Grafana! We've had some congestion issues due to poor config in my area, and this has helped me pinpoint which nodes are causing the biggest problems, and block them at my repeater.

I have a Seeed SenseCAP T1000-E running fw 2.7.3 and with boosted gain turned off my node drained to 5% in 3 days and 6 hours. With boosted gain on though i have only gotten 2 days 15 hours to 7%. I know they are not the same, but i doubt i would get 16 more hours out of it.

I just went through some frustration. I recently got a T-Deck Plus and I really like it. Now that the standard firmware for it supports the expanded UI a lot of the gaps I've ready about seem to have been filled in.

My only complaint is that I wish it had better battery life. AlleyCat designed a replacement case back for it that will hold an 8000 mAh battery (it comes with 2000 mAh). It is certainly thicker, but not really too bad, and 4x the battery life would be worth that for me.

Unfortunately, it doesn't fit. Lilygo has apparently made some changes to the hardware since the Plus came out. I've seen pictures of them with the AlleyCat case back installed, so I know it used to fit. When I measure the inside of the bottom section with a caliper, the new case back is around 1.5mm narrower than the one it came with. That is more than enough to keep it from working.

There were also several other differences that would cause problems. The reset button has changed, which could be worked around. The speaker has changed so that it can't overlap with the battery, which is another showstopper.

I'm in favor of manufacturers improving designs. I just wish they would assign clear version numbers to them so we could tell what we're getting.

The device itself is great. Just don't count on the after-market for upgrades.

Hey all,

I have a heltec v3 and a raspberry pi and im looking to see how i can use my rpi to interface with the heltec device via bluetooth. Anyone have experience doing this? Id like to potentially have a web gui but also interested in using the python package to send messages based on some events ill be creating.

Remote device Cleric Repeater has advertised your public key. This may indicate a low-entropy key. You may need to regenerate your public keys.

What should I do?

Meshtastic developers released firmware version 2.6.11 with critical fixes:

Key generation delay: Keys are now generated when users first set their LoRa region, preventing vendor-side duplication. Entropy improvements: Added multiple randomness sources to strengthen cryptographic initialization. Compromised key detection: Devices now warn users if known vulnerable keys are detected. An upcoming version (2.6.12) will automatically wipe compromised keys. For immediate protection, users should:

Update devices to firmware 2.6.11 or later. Perform a factory reset using Meshtastic’s CLI: meshtastic –factory-reset-device. Manually generate high-entropy keys via OpenSSL for critical deployments.

So I just noticed that my local router has been up for 170 days. It has the public-private key cryptography introduced in version 2.5 because it has the lock icon. But since it's been up for 170 days, I know for a fact that it does not have version 2.6 at all, and there was two key issues fixed in 2.6.3(ish and 2.6.11.

Hey all, sorry for the probably dumb question but I am new to this and don't want to blow a board....

I have a rak 19007 board powered by a lipo. My question is if I need to disconnect the battery to charge it? Or can I just leave it hooked up, add power via USB c or solar, and have everything work ok (battery charged and then device is powered by the external source)?

Ive been having fun with this software for a bit. Anyone have a list of other software they like to use for meshtastic (other than the official client)?

I heard an Talk about this. And wanna try this on an Connection between LoRadevice and Wifi and an old smartphone. When i have Time.

Hi, I added a buzzer to my RPI pico w, T3S3 and T-Beam Supreme and the RPI and T3S3 do beep during startup and the T3S3 seems to beep on some messages but not when I send a direct bell signal or message. Is there a better documentation explaining what options di what? I can’t get it work.

Hey all,
I accidentally purchased a battery for my T114 with the wrong connector. I am looking at just purchasing some JST connectors and changing the connector myself.

Is there any danger to do this while the cable is still connected to the battery?

The battery is a 803040 1000mAH 3.7V battery

Ihave a unique opportunity to add a node at the Tower LNB ring. However I'm struggling to source a Meshtastic gateway that meets the requirements I'v been given. Any help would be appreciated.

1. Power will be provided over 48v POE ONLY
2. Remote management is a must, consider both internet provided over ethernet and 4G/LTE as backup (fw updates)
3. Maximum 5db gain antenna can be used positioned on the LNB ring facing N-NW, must not exceed 1400mm in length
4. Must be tuned for exactly 915mhz (l'm thinking cavity filter) to help with Rx.
5. Enclosure and antenna must be pole mounted
6. Absolutely no wifi 2.4 or 5ghz
7. 500CND budget 'd like a set it and forget it approach. ls it even worth it?

Question about antennas. Is there a limit regarding size of an antenna that can be used on a device like the heltec t114?

For example, I have a old 8ft Lora Antenna that was used for the helium network at one point

It comes in 5,000 mAh and 10,000 mAh variants and will use 95% of the battery in power bank mode and reserve the bottom 5% to run the mesh node. I think you can run the mesh node and use all 100% of the battery if you wish, but the power bank mode can only use 95% of it. I think it's based on the NRF52 and SX1262 radio.

Edit: Sorry for the duplicate post. Please feel free to delete it, because I can't figure out how to.

Well this is interesting. Stick-a-node to any smartphone with magnetic back. I could see myself trying this.
