ANDELI Smart Switch Review: Turn Any Water Heater Smart for $15

The Problem: A Dumb Water Heater in a Smart Home Era

I've been dealing with a perfectly functional electric water heater that had zero smart features. Every morning meant trudging downstairs to flip a switch and wait 30 minutes for hot water. Rather than replacing a working appliance, I wanted a retrofit solution. That's when I found this ANDELI Tuya smart switch for $15. I've been testing it for a month.

What You Actually Get

The ANDELI switch sits between your existing water heater and your electrical panel, essentially making any "dumb" appliance controllable via WiFi. It handles up to 4400W, which covers most residential water heaters and AC units. Setup happens through the Tuya Smart app, which integrates with Alexa, Google Home, and Alice voice assistants.

Installation requires basic electrical knowledge. You'll need to shut off power, disconnect your existing setup, and wire this switch inline. The instructions are clear, though several users mention the device is slightly larger than standard switch boxes expect.

What Works Well and What Doesn't

Response time impressed me most. Commands from the app reach the device in under 2 seconds. Scheduling works flawlessly - I set it to turn on 30 minutes before my alarm and wake up to hot water. Voice commands through Alexa are instant.

The main limitation is physical size. I had to file down part of my existing switch frame to make it fit properly. It's not difficult work, but worth noting upfront. Also, if your home's electrical system is older, you might want professional installation.

Price: $15.13 (was $26.60)

What $15 Usually Gets You

At this price point, you typically find basic switches without connectivity, or smart switches from unknown brands with buggy apps. Established smart switch brands start around $25-35. The ANDELI's advantage is using the Tuya ecosystem, which supports hundreds of devices and gets regular updates.

Compared to replacing an entire water heater with a smart model ($300-600), this solution costs 20 times less while delivering the same practical result.

My Honest Take

Buy it if: You have a working water heater or AC unit that lacks smart features, and you're comfortable with basic electrical work. Great choice if you're already in the Tuya ecosystem or want to start smart home automation affordably.

Skip it if: Your electrical setup is outdated, you're not comfortable working with electrical connections, or you need temperature control (this only handles on/off).

After a month of daily use: 8/10. It does exactly what it promises at an unbeatable price point.
