Control pool lights

I was thinking about adding lights like these to a pool Homly Pool Lights, Led Pool Lights for Inground Pool, Magnetic Pool Light for Above Ground Pool Lights with Suction Cups, Ip68 Waterproof Led Light, Underwater Lights Color Changing Led Lights 4 Sets

Any thoughts on an easy way to control them from HA?

Look like ir remote

It is controllable but where would you put it blaster?

The ad says RF.

I would play with esphome.

Is there an easy way to tell what frequency the rf is?

That is a question I don’t know the answer to. Ask the vendor?
