The lamp can be controlled both via Bluetooth using the Hue system and via the button on the lamp, even when it is operated with a cable. This means you can switch it on and off via Bluetooth when it is operated with a cable without always having to press the On button on the lamp.
You can set up routines for Philips Hue lamps without a Hue Bridge by using the Philips Hue Bluetooth app. This app allows you to control up to 10 lights and perform simple control functions such as dimming or colour changes. However, advanced functions such as automatic switching on at certain times are limited without a bridge or other centralised control. However, you can use IFTTT to create such automations by creating applets that control the lights based on specific events.
Yes, your lamp can be used without a mobile or an app. The Philips Hue Go Base BT (520 lm) has a button directly on the device that can be used to switch the light on and off, dim it and cycle through different colours and lighting effects. Your son can therefore use the lamp as a bedside light or mood light in his room without the need for a mobile or an app.
You can control the Philips Hue Go Base BT (520 lm) with the Philips Hue Bluetooth app, at no extra cost or subscription. This app allows you to control the lamp via Bluetooth, including switching on and off, dimming and changing colour, without the need for the Philips Hue Bridge or a subscription.
The app you downloaded that leads to "Subscribe Now" could be the full Philips Hue app, which offers additional functions and integrations with the Hue Bridge, but for the basic functions of the Hue Go Basis BT, the Philips Hue Bluetooth app is sufficient.
The Philips Hue Go lamps, especially the "Go Basis BT (520 lm)" model, cannot be connected directly to the Hue Sync Box. The Hue Sync Box is primarily designed to synchronise the light with images and sound from screens and game consoles, and it requires a connection via the Hue Bridge to use these functions. However, the Philips Hue Go bulbs can be controlled via the Hue Bridge, but they are not specifically compatible with the Sync Box function without using the Hue Bridge.
Unfortunately I cannot answer your question. And this has nothing to do with the lamp itself. In fact, since this purchase was not what I was looking for, I gave the object to someone who could use it with satisfaction.
I'm sorry!
The lamp is suitable for reading. It's also good for waking up. All you have to do is install the Hue app. You can then simulate a sunrise, so to speak. My whole flat is equipped with Hue products. I can only recommend it!
