Locating Meshtastic Node Near Other IoT Devices

Ooh! It just occurred to me that I can ask this here:

Does anyone own/operate a LoRa mesh node?

I have a Seeed Solar mesh radio located on the same pole with outdoor
sensors of my Ecowitt GW3000. Ecowitt seems reliable, but I'm
not happy with the signal strength of more distant mesh nodes at mine
and vice versa. I'm wondering about interference with Ecowitt.

Does anyone have experience with such a setup?

If you want range, you might want to look into WiFi HaLow as that has been tested across a valley at 2Mb for 16 km with LOS.

Without LOS some videos on YouTube have shown 2-3km.

The good thing about standards based products is you don't need to mess about with proprietary protocols, everything you need to worry about is TCP/IP

Hi Chuck,

It depends on what band your LoRa kit is on and what band your GW3000 is on.

If they share the same ISM band i.e. both on 915MHz, then yes, the LoRa
kit has the potential to interfere with the reception of the GW3000.

I know this for a fact in that I had a DMR hotspot on 440MHz and its
transmissions deafened the receiver in my GW2000 ( 433MHz ). It couldn't
reliably hear my soil moisture sensors until I moved the hotspot.

Moving the hotspot to the other side of the house fixed the issue.


regards

Tim

Sorry, I'm not worried about Ecowitt distance. I'm worried about
Meshtastic distance and concerned that Ecowitt is interfering on the
same frequency.

Yes, Meshtastic and Ecowitt share the same frequency. Ackshually,
they do it pretty well, I think. I see no problem with Ecowitt.
Meshtastic distance is disappointing. I have a high-gain outdoor
antenna on a solar-powered node, but a whip antenna on a portable
indoor node works almost as well. It's difficult to tell because both
nodes relay for one another. On the rare occasions when I can get
results from *TraceRoute*, the signal/noise SNR outbound from the
outdoor node is decent even though the inbound is marginal, which — to
me — indicates that the broadcast power of the remote node is
insufficient. But I could be whistling Dixie.

[sort of off topic, only once]

I would expect that the ecowitt stuff transmits short bursts
occasionally. And thus that any interference affects fairly few
meshtastic packets, and you might see a slowdown in a big file transfer,
but not "never works all that well".

SNR is signal to noise ratio. That's different than received power. If
it's not so good, could be lower signal or more noise. Also different
chipsets probably measure differently, so not so comparable. I would
focus on % of packets received for some specific transmitter setup;
that's the metric that really matters even if SNR is useful for
adjustments and a proxy for packets decodes.

Yes, things get through.

Packets received is pretty messy. I don't control the receiver nodes,
but I get reports of missing messages that are sequence-numbered.
