• Home Assistant Yellow installation with NVMe SSD drive and CM4 Lite
• Ethernet cable

Additionally, make sure you have the following items which are not part of the Kit

• Raspberry Pi Compute Module 5 Lite
• USB-C cable
• Heat sink: You can use the heat sink shipped with Yellow.
  • If you want, you can also use the Raspberry Pi Compute Module 5 Passive Cooler.
  • Note: the Raspberry Pi Compute Module 5 Active Cooler is not supported on Home Assistant Yellow.
    • There is no fan plug providing the required 5V and PWM signals.
• If you are using PoE, make sure your router or switch provides PoE on that port
• Optional: Power supply (12 V / 2 A, if PoE is not used)
• Flat nose pliers

1. Remove the 4 screws on the bottom of the Home Assistant Yellow Kit.
2. Keep the thumb screws close by; you will need them again later.

1. Make sure the interfaces are facing towards your left.
2. Flip the case over.
3. Slightly lift off the enclosure on your left.
4. Slide the enclosure off towards your right.

• Use the pliers and squeeze the front of the pin so that it fits through the hole.
• Repeat the procedure for the other pin.

• Remove the Raspberry Pi Compute Module.
  • The image shows a Raspberry Pi Compute Module 4. The steps are the same for the Compute Module 5.

1. Place the board in front of you, the connectors facing to the right.
2. Orient the CM5: the Raspberry Pi text needs to be on the right hand side.
3. Carefully place the CM5 without force.
   • The CM5 should fall into place slightly when correctly aligned.

• Press the CM5 board onto the board-to-board connectors until it clicks into place.

  1. Make sure you press on both sides (the two long edges).

     • This requires quite a bit of force.
     • If you don't hear a loud click, it is most likely not fully seated.
     • Note: It has been reported that on some boards, there is no click sound when pressing the module onto the board. It can still be seated correctly.

  2. Do a visual check to make sure the CM5 is installed correctly.

     • It needs to run parallel to the Home Assistant Yellow board.
     • You can also pull a bit on the sides to make sure it is not loose.

1. If your Yellow came with a plastic bag labelled CM5, containing screws and heat pads, place those heat pads on the CM5.
2. Align the pads as shown in the image.
3. Make sure that the pad with the cut off corner is placed so that there is room for the screw.

1. If the packaging included a plastic bag labelled CM5 with screws and heat pads, you have the option to screw the CM5 module in place.
2. Screws are optional and can help keep the Compute Module in place during transportation.
3. Use a No 1 crosshead screwdriver.
4. Be careful not to overtighten the screws.

1. Push the 2 plastic push pins into the dedicated hole on the heat sink.
2. Start by first aligning the right plastic push pins into the dedicated hole on the carrier board.
3. Then, place the heat sink onto the module.

1. Take the entire board off your workplace and push the pins firmly through the carrier board.
2. Ensure that the module is still fully seated after securing the heat sink.

1. Place the translucent bottom part of the case onto the table.
2. Make sure the two round notches form a line pointing towards the top right corner.

1. Place the board onto the bottom part of the case.
2. Make sure the USB connectors are facing upwards, away from you.

1. Turn the enclosure upside down.
2. Then, slide the push buttons into the openings of the case.

• Insert the 4 thumb screws.

• Plug in your Ethernet cable and make sure it is locked into place.
• The other end of the Ethernet cable will need to be connected to your router or switch and connected to the internet.
• If you are not using PoE, connect the power to the wall and then to the Home Assistant Yellow.

Notice: Initial startup may take a while, depending on your internet connection.

1. Open Home Assistant.

   Mobile: Confirm the IP address detected by the app. For example http://192.168.1.196:8123

   Desktop: Visit http://homeassistant.local:8123 to access the Home Assistant user interface.

2. As your data is stored on the NVMe, your dashboard comes up as usual. No additional steps required.
