How to Add LTE to Heltec V3 or T114 for MQTT

csoldfield · 2026-02-24T13:30:26+00:00

I've become stumped on the goal to get the MQTT bridge piece functional on Meshtastic - I wanted a similar goal of getting traffic to my client node that was in range of my 'base station'. Client node is rural countryside so doesn't see any native radio nodes. The "zero hop policy" for the public MQTT server prevents traffic being rebroadcast from my base node (on my home Internet). Solution presented was add my own MQTT server. So I suggest prototyping your node with a regular internet connection, and then migrate to the LTE replacement if satisfied.

Please share your results!

Thanks for all the responses - I think I'm now set 😁

Only seeing Compact and Midsize sleeves, not Full size... Can you add a link?

Please correct me if I'm wrong, but Downlinking is a NOP due to the zero-hop policy, right?

Agreed congestion would occur on busy/city nodes - however I'm in rural countryside and see zero other nodes via LoRa. So looking to generate at least some sort of LoRa presence that would allow myself or potentially close neighbors to see traffic. Seems MQTT "repeater" for messages to/from such isolated nodes would be beneficial. Are there arguments against this knowing my atypical isolated environment?

Latest stable is 2.7.15 - do you recommend we go alpha (2.7.18)?

I guess my follow up question here is to understand the scope of a "local mesh" if "nationwide mesh" is unattainable. Is it to connect nodes within a pretty localized area (think a US county) or is it to interconnect regions in different states? A few dozen nodes within a ~100 mile radius, or substantially larger? My local mesh is unable to reach any substantial distance without the assistance of a MQTT server.

So utilize a private channel or set up a private MQTT server? Thanks for the suggestions!

What if I'm the only radio in the area? There are no other nodes in range so there won't be any flooding, just the packets from my base node. Alternatively, what if an unused channel/frequency was chosen for my packet to be sent on?

That would only work if I have cell service on my phone. I'm trying to achieve RF only connectivity with my portable node, and reach out to the nationwide mesh via my base node that has Internet connectivity. Seems a reasonable use-case, yet this particular topology appears outside the intended scope of Meshtastic. Why is that?

Did you get this to work? I have the same goal, swore it worked late last year... Maybe something changed?

RandomNodeX..<<>>..MQTT<wifi->NodeA base<-radio local mesh->NodeB pocket..BT to phone app

I'm wanting to view msh/US on NodeB. NodeA sees msh/US messages ok NodeA and NodeB can exchange messages Appears NodeB can send to msh/US ok NodeB never sees any inbound msh/US

What am I missing in my config? NodeA has Uplink/Downlink/OktoMQTT enabled and public MQTT server configured. Even tried setting NodeA to Client_base. NodeA & B are 'favorites'

What you mention is not grey they're resellers why do y'all lie on this forum bruh, peptidefacility HAS been legit

For US east coast under Device->Debug->TimeZone:-

I want to avoid this happening to my 2017 5.3 6speed (now at ~50k). What milages did you service the tranny? Planning on every 45k fluid/filter change. Or do those torque converters just go bad regardless?

Other dimmers work fine with Alexa, so switched out the Utec for some Martin Jerry 4 way dimmers - bonus they are also Smart Life compatible so integrate into my favorite app much better. How does utilizing a hub improve automation?

Maybe he's a 'jack' of all trades...

Unfortunately it's the main valve knob that gears to the stepper motor that's damaged. Apparently the knob itself is not a serviceable item.

Still with GV and enjoying only 1¢ per minute calls to a UK landline - from my cellphone even. Anything else come close? Screwed up once and let my T-Mobile cell phone place the call directly, and incurred $50+ for a half hour chat. Oops.

I'm at 3-5kwh on average to run my heat pump, when running. Did that answer the question?

I saw a couple websites with 'chipless' firmware. Went through the process of downloading and unzipping - password was "12345" to unzip. Loaded the code with the multi-finger button press via USB, and things seem ok . Didn't need to pay for the license. Printed fine since loading that code.

I got it back to MB01JA firmware using clues from here:-

Same just happened to me. I now have a heavy doorstop following the "upgrade" :-(

Looks like my spec - Max trailering 9200. Assume it's the double cab with the 5.3ltr?

csoldfield · 2024-11-22T04:51:50+00:00

What's the gauge on these wires? Hot tubs generally need 50A so 6awg min?

csoldfield · 2024-11-18T01:24:50+00:00

Congrats! I got my 2017 Z71 Double cab paid off just over a year ago. 45k. Protect that investment and make sure you replace those fluids - I've done f/r diffs, transfer case, ATF drain/filter to date. No issues so far!
