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

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

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.

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.

The Shelly products are all really good, the only negative is that the modules can be difficult to pair

The Shelly 1PM is working as expected. Switching A Refer & Freezer.

These Shelly device terminals are not safe for use on 20A circuits which are standard for home built in US in last 15-20 years. Reducing from 12 to 14 is a fire hazard according to my building inspector. I have my doubts on this as my lights are all LED and if they weren’t their are only 4 and would over load 14Ga wiring still it isn’t allowed to lower gauge until the plug. Most appliance only have 14/16 Ga cord.

Product information table in Amazon is incorrect! This is not a temperature switch it is a relay.
