On my list of hardware/software to experiment with is [Wayback/Archive] Meshtastic:
An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices
Via [Wayback/Archive] @jilles_com@infosec.exchange on Twitter: “Will be taking to meshtastic.org Lora 433MHz modules to @hotelhacker. Might be cool if more people could bring some to setup a larger mesh and play with them. amzn.eu/d/aCgULy4“
Products:
For both boards, this holds:
1. The Meshtastic program is not pre-installed on this product. If you need to install, please check the steps:
github.com/geeksville/Meshtastic-Android/blob/master/README.md
github.com/meshtastic/meshtastic-device/releases
2. If GPS does not work, the following situations may occur:
Install the Meshtastic firmware before and now reset the GPS when you switch to another firmware.
Reset steps: github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/firmware/GPS_%20reset_test
3. If GPS is weak indoors, it can be used outdoors
4. The GPS antenna is not installed stably, you can check if the interface is attached to the GPS antenna

This was a cool post: [Wayback/Archive] 433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors – CNX Software
433MHz LoRa Transceiver-based ESP32 board work with regular 433 MHz sensors found on the market. This gives end users a simple off-the-shelf solution for receiving these signals without having to use a soldering iron and making a circuit.
…
This opens many doors regarding 433 MHz sensor readings with one device, including weather stations, doors, PIR, TPMS, temperature, and BBQ sensors.
Recommended reading!

I have seen too many sites where cabling was laid en never tested before actual use, which meant locating the cabling and faults was a nightmare.
Be sure to have good (which can be very simple, but more complex when Power over Ethernet is involved) testing hardware and use it during installation. You will thank yourself later.
A few videos that can be helpful:

I have been contemplating on pfSense hardware as there has been a large shortage on that market especially for having more than 2 ports (similar to for instance Mikrotik PoE router unavailability).
If by now I have not found any, I might want to revisit [Wayback/Archive] Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up – CNX Software has 3 RJ45 ports and 2 SFP+ cages.
They found it via this 4 page review:

[Wayback/Archive] GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support which can do many-to-one port mirroring.
This is a newer and cheaper hardware revision than the:
- GS105Ev2 (which is managed and can do port-mirroring, and is confusingly sold as GS105E-200) which in Germany already is end-of-life
- GS105Ev1 (which is unmanaged and cannot do port-mirroring and is confusingly sold as GS105E-100) which is end-of-life but still sold
Via [Wayback/Archive] Everyone Should Have One of These – EASY Packet Capture! – YouTube who explains very well why you need a switch that can do port-mirroring, then recommends the GS105E but forgets to mention:
- there are different revisions of the GS105E with the above drawbacks
- there is GS305E
