## Description

Shelly 1 PM Relay Switch, WiFi Smart Home Automation, Compatible with Alexa & Google Home, iOS Android App, No Hub Required, Wireless Light Switch, Smart Appliances Gadgets, UL, 4 Pack - desertcart.com

Review: Work great with single or 3-way switches - I love these relays. I was able to set my exterior lights to turn on/off based on sunrise/sunset. I went with these over an astronomic timer switch because I kept the clean look of my normal light switch. I also love the way it integrated with my 3-way switches. I am able to still turn it on/off from either switch, from the app, and automate on/off times. I used the timer feature on the bathroom fan so the fan will stay on 10min after someone wrecks the bathroom. Awesome
Review: Dismayed over another, 4th, failure. Limiting review to a likely Gen 1 unit. - After I inherited a house, I decided to automate lights, pool pumps, etc. as a means to control power, ensure equipment was running, make the place look lived in, and automate this with HomeAssistant. Worked great to start, but over time, these Shellys have been becoming problematic and just dying off. I've removed at least 4 now, with today's being the pool pump which, with water flow requirements, controls the chlorine generator (saltwater pool). My only solution is to remove ensuring the pool doesn't go green, or spend more money replacing and possibly having another future issue. I am sad to say I have removed the Shelly 1PM. This is unfortunate because I was able to use the Shelly power monitoring with Node Red in HomeAssistant to remotely determine when the salt cell needed cleaning. Disclaimer so not to impute subsequent model improvements: I believe my Shelly is a Gen 1 device. Subsequent generations may have dealt with my issues, but I am not able to reinvest more money to find out.

## Questions & Answers

**Q: Does this model need a neutral wire? and if yes what is an alternative that is the same size but doesn't need a neutral wire?**
A: First, you're not going to find a smart relay that doesn't require a neutral wire. It just doesn't work.

Second, there's a neutral wire involved in any wiring set-up, you just have to find it. In your case, if there's no neutral wire in the switch, then that means the wiring runs breaker-fixture-switch instead of breaker-switch-fixture. You can still use one of these relays, you just need to put it in the fixture junction box instead of the switch junction box. I had to do that in my office in my house, and it works just fine. Disconnecting and reconnecting a ceiling light fixture is a little more of a hassle than doing a wall switch, but it does work.

**Q: Is this switch UL Listed?**
A: They are now.

**Q: If connected to a traditional switch, how does the rocker work if you want to control manually?  Does either up or down turn on and off?**
A: Basically what it does is it’s a remote shut off switch. So if the switch is on when remotely shut off, you will have to turn off, then back on for manual use, and if off, you just flip it on then off, to turn it off

**Q: Is there a way to use this switch to convert my buried in the wall, not-smart, 2 wall switch, no neutral wire, 3-way light circuit to be "smart"? How?**
A: The switch has relays which can be controlled by MQTT plus they have an app and a public API you can communicate with if you have development skills.

It does say it support Alexa and Google home but I didn't use that functionality - but I assume it links to the above-mentioned API endpoints? The Shelly website is very comprehensive, and they have a good support team so it might be worth checking with them.

Otherwise, it's probably not what you're looking for. It's more a foundation for someone to build IoT devices on rather than a 'smart' switch like the kind of thing you'd find in Best Buy or a similar retail store aimed at regular consumers. It *will* switch 120v/220v loads though (check the amps and elec specs to be safe) so it could be suitable for your use case assuming the Smart Home integration can do what you need.

### ⭐⭐ Dismayed over another, 4th, failure. Limiting review to a likely Gen 1 unit.

### ⭐⭐⭐⭐⭐ cloud-free!
*by M***4 on December 11, 2022*

Local management without the cloud is easily accomplished through Home Assistant. Also, the stock firmware provides a lot of useful stand-alone functionality. These are so much better than the every day smart plug locked to an app.
