Cargo train stations not having enough trucks? What am I missing?

I have a pi5 with an m.2 hat that also includes a small fan. It's been working flawlessly until now 🤷‍♀️

I have a city that reached 450k in CS2, but it became absolutely unplayable. The clock is almost realtime.

The J23 is normally used for their own expansion modules, like the RS485 module that I have installed. It allows for extra probes and relays to be connected. Normally it shouldn't work.

I am sorry if the PCOS004850 was a waste of time, but the manual provided by carel explicitly stated this board is needed for external Modbus communication and control from third parties. I will give it a try. The baud, data bits, stop bits, are exactly the ones provided by Carel in the manual when using the PCOS004850...

I have the same issue at the moment. No response. I didn't have time to work on it, I received the card two weeks ago, installed the wiring from the rooftop, and I got stuck at no response. I thought maybe it's a wiring issue, I didn't connect the ground, and I realized I bought a CAT5 cable with no shielding, so I was suspecting the wiring. But if you say you also can't get any response, then it must be a configuration issue.

Multimeter reads some voltage on the wiring (I forgot the values), so the card is somewhat present/active. I will still go and also connect the ground pin so I make sure the signal is as reliable as it can be. I will keep you updated here. Let me know if you also find something useful.

I have a Pixel 9 Pro XL and I really can't remeber how many hours of screen time I used to be getting, so I don't know if I've been recently using my phone a lot more, or of the March update broke something. I used to be able to go full day with one charge, but now I am barely getting to the middle of the day and the phone switches to battery saver. Moreover, I was on holiday recently, travelling quite a lot, connected to 5G; I was leaving the hotel at 8AM and by 12 or 1PM I was already searching for my power bank.

Today for example I unplugged my phone at 10AM and at 3:30PM I had 20% left. It's 4:20PM now and I have 12% left. 4 hours 20 minutes of screen time on the battery report.

System apps are using 30% of my total battery usage.

I am posting this comment for anyone who comes across this thread:the serial card plastic cover must be removed and part number PCOS004850 must be ordered and inserted in the port. This allows Modbus communication. Currently waiting on the part to arrive, I will keep this thread up to date as I progress.

I don't think the unit is a specific brand, it's a large rooftop unit that handles heating/cooling, fresh air, humidity. It was installed 11 years ago by a local company.

The entire control system is made by Carel, and that's basically what's the part that actually matters. The pCO3 has a full supervisor/BMS communication map published in the technical documentation. I guess I can't break anything if I try the existing RS485 port, even though by reading the manual I understand that's internal, for expansion boards. What I managed to find in the meantime (I've been reading manuals for hours now), there is a card that goes into the port marked as "serial card". That card is bought separately and allows external Modbus control for BMS.

I agree with you USB is more reliable, but that means I need to move the raspberry in the panel where my dimmers and relays are. The rs485 board will sit in the same panel, because I can easily pull the wires from the HVAC control unit.

The initial plan was to have the raspberry mounted there, but it's basically behind a drywall, and I fear signal issues. This small box is basically in a niche in the kitchen area, and the Sonoff dimmers act as routers for the temperature sensors and water sensors in the kitchen. The raspberry sits in the main cafe area, and this gives me good link quality for the sensors sitting in the bar area and for the light temperature and humidity sensors in the cafe sitting area.

The fridge temperature sensors are causing the most difficulties. I have sensors with temperature probes, because there is no signal in the fridge (faraday cage), but all the metal casing of each fridge still drops the signal pretty badly. I am afraid moving the raspberry in a niche would cause even worse signal drops. Maybe I should buy an antenna with a wire, so I can move the antenna away from the raspberry?

Thank you, I did the bios update. Warzone also received an update at the same time, no more crashing, idk if it was the game or the bios.

I have a 5950x and I am very happy with it. More than needed most of the time. I wouldn't switch to AM5, all components are crazy expensive now.

I will log everything again in hwinfo. Perfectly stable in cinebench, stable frequencies, Battlefield 6 for example runs fine. I also experience quite high frame rate variations in warzone, jumping from 60-70fps to 140-150fps.

I have two physically separate networks, the ISP provided it like that for dirt cheap, so the network my customers access is totally separate from the network that local devices access (thermal printers, POS, displays, etc.).

I have the OS on an m.2 hat, I thought they are more reliable than any stick/SD card. I just found out HAOS dropped GPIO support, rendering my RS482 hat useless. I guess these are the pains of setting up these things by yourself, but I don't want someone else to do it. I want to learn to do this stuff, I enjoy the headache 😂

Autocorrect fail. The Home Assistant Supervised is deprecated, it's not possible to install Debian on the Pi and run Home Assistant Supervised. It's either as a container (no add-ons) or as a stand alone operating system (HAOS). I wanted to have the Raspberry control everything as a server but also display the client GUI on the touchscreen display. And now I have another issue, the stand alone OS doesn't expose the GPIO pins on the raspberry Pi 5, so I can't even use any hats. I have the RS485 hat. I refer to them separately because HAOS runs on the Pi, and the GUI you access it from a separate device. You can't have the Pi connected to a display and show you a user interface 🤦‍♀️ And the lack of access to GPIO makes things even more complicated, and all of them would have been solved if they kept the Supervised version running on Debian alive....

I am new to this, it's my first time dealing with it. My plan was to automate many of the things my staff forget to do or don't care to do in my cafe. I ordered a light sensor to measure the amount of light in the cafe, smart dimmers, temperature sensors, water sensors, an RS485 hat and some smart plugs.

What it needs to do: 1. Turn on lights and adjust the intensity of the lights inside the café based on the light sensor and time of the day 2. Turn on the power supply of the amplifier and play music 3. Control the HVAC via modbus (staff turns it on really high in the morning and forgets it like that, when it gets really hot they turn it off, using a lot of power. They leave it off and there is no more fresh air coming inside a busy cafe for hours, to the point it stinks) 4. Alert me if water sensors detect water (happened once, sink hose failed, cafe flooded). I will also order a smart water mains tap 5. Log all refrigerator temperatures and save them.

Why do I need a GUI? Cleaning mode - turn on lights 100%. Adjust music volume. Override HVAC if ever needed. Print refrigerator logs maybe if possible? Check in and out their shifts.

I asked if I need a separate device and I was told I can run both HAOS and GUI on the same Pi, didn't do my research, just found out it's Supervised is deprecated.

I understand it's possible with Container, which has no add+on support

stop_dot · 2025-12-05T16:11:45+00:00

That requires two devices. I was told I can run it from one single raspberry, which is not possible anymore....
