I purchased this landscape light timer to replace a Malibu transformer that stopped working. https://amzn.to/4azXzfq I have a number of products from the Suraielec brand and I've been very happy with them.
This was easy to connect to Alexa (except the instructions say to push and hold the reset button instead of the power button to start the setup mode.) It works with the SmartLife app, which is much better than having a proprietary app.

I also have the Suraielec Pool Timer https://amzn.to/3PGigOF
And a different Suralec Landscape Light Transformer at a different location https://amzn.to/49bdek4
These are the best products.
