ShellyWave 1PM US UL | Z-Wave Smart Switch Relay, 1-Channel 15A Dry Contact | Home Automation | Z-Wave Repeater | Low Power Consumption | High Compatibility | Easy Installation | iOS Android App

I have about 80 Zigbee and Z-Wave devices currently in use. Setup with SmartThings hub v2.This little device is very compact, well engineered and reliable. The team goes out of their way to test compatibility on the top smart home platforms which I have not seen any other manufacturer do. They also publish the results of their testing, so when you buy their product you don’t need to guess if it works on your platform or not or which functions will work and which will not.The device is very compact and should fit in most US home sockets - power outlets, switches or light fixture end points in the ceiling (my current use)Pairing is easy, removal from the smart network is also easy.A few suggest to the design team:- change the terminal screws to Philips type vs flat.- the sockets are too shallow, make them deeper in order to ensure good connection and more importantly to avoid customers fro leaving exposed wires which can create a short if not stripped to the exact length - especially in which close proximity next to each other - line and neutral.- make the wire terminals with wider diameter - USA operates on 110v, not 240. We run bigger gauge wires for higher amps and the wires barely fit.- LED display vs Morse code type status LED 😀Great value and great value for the money.Pozdravlenia.

The amount of customization options, being UL certified and zwave. It works great, and works well with home assistant. I can even use the 2PM version with a 3 way switch. This 1PM will work with some 4way switch setups.The Reddit support is also phenomenal.It has lots of configs most “Home Depot” switches don’t have.

Device screw terminals will not work with #12 solid wire which is typical in US home wiring. It only works with stranded wire, which means in most US installations you will need to create a patchwork of stranded wire jumpers in the J Box to make this work.Also, unlike other smart switches or relays the device cannot be reset or added to the network by using the switch itself (at least it didn’t work for me). If you ever need to reset would require opening the J Box to press the S button (not a deal breaker just FYI).Does not support changing modes without opening J Box either.There is however utility of this device vs regular smart switches or outlets in certain conditions (like putting the switching relay at the fixture instead of at the switch)

I installed it in a crowded 2-gang box and it works quietly and well!
