Can these be grouped together if in a ceiling fan with 4 bulbs to turn all off at the same time?

Yes, you can use the Group feature in the Kasa app, or the Scene feature, to control four Kasa bulbs simultaneously.

Will these function correctly with an existing dimmer circuit?

If the dimmer is set to 100% at all times, it may work. However, we generally recommend against installing smart bulbs in an existing hardware dimmer, since it creates redundancy between each bulb's internal dimmer hardware and the dimmer on the circuit, which may lead to issues or inconveniences.

Do you have a smart bulb that emits daylight instead of soft light?

The KL125 offers adjustable color temperatures between 2500K (warm/soft white) to 6500K (daylight).

Will this work in a lamp that is on a nightstand?

Yes it will. You just leave the lamp on and either use the app to control it or a device like an Alexa.

Cumple con su función y a un excelente precio.

Excelente artículo para iniciar la automatización de una casa. Muy fácil de configurar. La aplicación permite planificar horarios de funcionamiento así como el comportamiento, color e intensidad de los focos. Los colores no son tan vibrantes como con marcas más caras, pero por el precio están muy bien (yo los encontré en descuento). En casi seis meses no me han fallado.
