Anyone Else using a Raspberry Pi 400?

[kenm]

Nice and clean. I like it. Unfortunately, I'm using a Pi400. so I'm limited in that regard. I've also found that most GPIO boards designed for the Pi4 do not work very well with the Pi400. You end of with the big "thing" hanging off the back of the Pi400. I'll probably pick up a Pi4 when they become more readily available again.

See my HS4 Pi4, it is an Wi-Fi AP, it is HS4 controller, it is also a VPN server, NTP server and UniFi controller. The short antenna is for Wi-Fi, only 2.75cm, the tall one is Z-Wave antenna for 850MHz-950MHz.

Impressive that you run everything. I could not manage to run HS on this device. It did not like my set-up .

Thanks. I think I'll go with an external USB dongle if the internal antenna doesn't cut it.

You don't need any video. Just find the Wi-Fi module RF out. cut out the trace, solder a u.fl connector and ground. that's it, very simple.

Ah. Makes sense. Do you have any links to YT videos? I can't find anything on doing the mod on the Pi400, only the Pi4.

Due to the space, you need to use u.fl connector. SMA is too big on the circuit board.

Have you done this is seen it done? I found some YT videos for doing it on a 4/4B, but I don't see the pads for an SMA connector on the 400.

TBH, I'd probably just use an external USB WiFi adapter with an antenna if it became a problem. It looks like the buster release has drivers for Realtek chips which are pretty common in external WiFi dongles.

If you know some electronics, you can modify Pi 400 board to use external antenna. external antenna will make wifi much better.

I have a Pi 400, and I found that its WiFi performance is quite poor. I gave up and now only use it with an Ethernet connection.

Noted, and Thanks. I'm going to keep an eye on it for now and see how it goes. If it becomes a problem, I'll just poke a hole in the firewall between my IoT and Control network, where HS4Pro and HS4Pi are running. The HS4Pi instance is really just somewhat of an experimental platform. I have several energy monitoring sensors that use http POST to publish readings. I wrote a Python3 service to receive those messages and re-publish them as MQTT messages. The sensors are on the IoT network (WiFi) and the MQTT messages are published on the Control network (wired). I also have a serial data logger (USB) and I plan on writing a Python3 service to poll the data in the logger and republish it as MQTT messages as well.

I have a UniFi network and for things like this, I force the device to a specific band and lock it to an AP. Any type of device with a weak WiFi signal can really mess with networks. The APs have a tendency to pass them around, hoping to get them better performance.

I am running a Pi4 using wifi with no issues... as the article says maybe it is more a router issue? I have an Orbi router and it tends to stick you on 5 if it can and doesn't like to move you to 2.4... which is an issue for my TV which needs the 2.4 for bandwidth.

You should not run HomeSeer with WiFi, else : https://support.thepihut.com/hc/en-u...-WiFi-problems

Not an issue. HS4Pi is bound to the wired interface. The WiFi is for communicating with IoT sensors (energy usage) that are on an isolated network.
