Having purchased the Kaiterra Laser Egg 2 and Apple's 10.5-inch iPad Pro together, we looked at how to use the iPad to set up the sensor. One of the advantages of using the iPad is that it can also be used as a HomeKit hub tto remotely control your HomeKit devices from the cloud (as long as the iPad is in the same vicinity as the HomeKit devices).
We first tried to set up the Kaiterra Laser Egg 2 using the Apple Home App on the 10.5-inch iPad Pro. However, the Kaiterra Laser Egg 2 didn't have a HomeKit code visible anywhere on its body or in the packaging like many other HomeKit devices, so we couldn't complete the Add Accessory step.
We then downloaded and installed the Kaiterra App from the Apple App Store. The Kaiterra App only had an iPhone version so we had to filter by iPhone Only when we searched for it.
Opening up the Kaiterra App for the first time, we had to accept several permissions.
We next could add a new device through the Kaiterra App. Even without the sensor being added, the Kaiterra App will report the air quality generally being reported in the city it sees you in.
After selecting the Add button, the only type of device available to add was the Kaiterra Laser Egg 2.
After selecting the home to add the Kaiterra Laser Egg 2 in, the Kaiterra App provided instructions that you press the mode button to set up the Wi-Fi connection.
On the Kaiterra Laser Egg 2, we first connected it to a USB AC adapter using the USB cable included with the sensor.
After pressing the power button, we then pressed the mode button for two seconds to start the Wi-Fi connection process.
The Kaiterra Laser Egg 2 also shows a QR Code which is popular in China which you can use your iPhone or iPad to scan and find the Kaiterra App.
On the Kaiterra App, after selecting Done in the Wi-Fi Setup menu, we could see the Kaiterra Laser Egg 2 show up in the Add Accessory window.
After selecting the Kaiterra Laser Egg 2, we then need to scan the HomeKit code to continue the pairing process.
Initially we couldn't get the HomeKit code to show up on the Kaiterra Laser Egg 2 but eventually it did show up on the display.
Our first attempt at scanning in the HomeKit code resulted in the Home App not being able to connect to the Kaiterra Laser Egg 2.
After a second attempt, we could successfully scan and add the Kaiterra Laser Egg 2 as a HomeKit accessory.
The Kaiterra Laser Egg 2 shows up as three different sensors- Air Quality, Humidity, and Temperature.
All these three sensors show in the Apple Home App.
Going back to the Kaiterra App, we could then finish the setup process of the Kaiterra Laser Egg 2.
Once the setup process is completed, we could use the Kaiterra App which is divided into My Air and Setting screens.
Despite a couple issues, we were able to eventually connect the Kaiterra Laser Egg 2 and Apple's 10.5-inch iPad Pro. Unlike some other sensors, you can read air quality information directly on the Kaiterra Laser Egg 2 itself so you don't need to use an App to get that information. However, using the 10.5-inch iPad Pro is useful to more easily change the settings and remotely control the Kaiterra Laser Egg 2 together with other HomeKit devices.
