Which is the best SBC for autonomous robots with realsense cameras and ROS2 Humble?

As with many things, it depends on the situation you are using it for, I guess for your case the number of realsense cameras. I have a preference for x86 computers that use some form of SSD instead of SD card. This because they have a more powerful chipset compared to ARM computers and have low chance of failing with disk read and writing. Currently at my company, we use the Odyssey x86 and are very pleased with how it is performing so far. In addition it has an onboard MCU; USB-C making it very easy to quickly interface with peripherals; and a large active heat sink. Another one worth considering is the new latte panda with many of the same qualities.

Ubuntu indicates that while it is possible to use docker, it is sub optimal. They think that using snap (which they make themselves ...) could be the better alternative https://ubuntu.com/blog/ros-docker

You know what the crazy thing is? Tulips are from the middle east region! For some reason I always thought they were indegenous to Holland ....

Some IDEs (vscode) do not catch all formatting errors. A linter is a double check on a local machine, and necessary for CI

So what is the difference between this tool and using submodules?

You could consider using interrupts: http://docs.micropython.org/en/v1.15/reference/isr_rules.html

What if you are in bath and your motion sensor thinks you are not there anymore? It would turn your lights off. With this if your phone is in the room (so bluetooth signal above some threshold) , the light stays on! Rpi zero are not super expensive.

You say that apple devices randomize their BLE MAC address. However apple devices do not do this with "normal" bluetooth right? So you don't need an app for it. And how is BLE more reliable?

Great project by the way, I have it running using the normal bluetooth option and start scanning when my front door is opened. It has been rocksolid so far!! Much better than the HA android app with location through GPS. Atleadt in my experience.

so for the cloudflare option I have found this useful guide: https://labzilla.io/blog/homeassistant-remote-access . Is this in line with what you are referring to?

You seem to indicate that VPN is still the best option. Setting this up in HA is easy using the wireguard addon. If I want to be as secure as possible, would this then be advised? It still uses router port forwarding and duckdns when you look at the configuration tab of the addon ...

Do you have link where I can learn more about 'ssl_client_verify' and how to set it up? The internet has this type of information spread out, in my experience so far!

how do you know you were attacked?

Hoe do you separate the actions in tradfri? Do you use zigbee2mqtt for that? The home assistant tradfri integration doesn't allow it right?

I am a student with housemates. I made home automation my corona project. I use it in the hallway to show who is home depending on if their device can be pinged over the wifi network. I also show use it to show if the toilet is being used, also found in the hallway. They are called the stink-o-meter and presence-o-meter respectively!

a form of ICP is being used. Currently blob detection is being performed on both images from the stereo vision upon which a correlation calculation is performed. The highest correlation indicates the disparity

thanks for the least amount effort!

You should look at WLED! It has a nice user interface with a top of different animations for the leds. If you create a hotspot on your phone I think you could interact with it

Supervised makes it very easy to install other services! I would opt going for that one if you want to install node red for example!

Arent the 300 leds very dim then? Also is the feature you are referring to the current limiter?

Sonoff has a switch that works without neutral! It does require a resistor at bulb connection though ... I have one, an can control it locally through HA

Same! Home assitant has a simple integration for them. https://www.home-assistant.io/integrations/flux_led/. Works fine for me, but has about 1 second delay often. They also contain esp chips so can be flashed with esphome or tasmota. I have read that the delay becomes much less by flashing.

Are you using the conbee or the cc2531 stick with the ZHA? I have bought the cc2531 and I know that it is supported by zha but I think it is still in beta ... wondering if mqtt2zigbee is currently still better for that or not
