Shelly Plus Uni Smart Wi-Fi and Bluetooth Operated Module, Dry Contact

Extremely pleased with Plus UNI devices I purchased. Using to remotely control (both automatically and manually) load transfer power relays between house mains and solar powered inverters; and monitor battery bank voltage. Was pleased that once router password was entered for the first device, others came online without having to reenter it.

Shelly does the job and does it efficiently, discretely, humbly and right. It does not force you to use someone's "cloud", does not force you to share your personal information, does not require you to know soldering or programming. I can solder, I can code but shelly turns out to be quicker and more reliable solution to nearly all my home automation projects.

Works well. Wifi range is not as advertised. App is not simple to use.

It's like the Raspberry Pi of automation. The device is inexpensive and has a lot of features. The online information is scattered throughout the world so you may have to get up to speed a bit on them. For the simple task I needed this was great. I monitor battery in garage via wifi. The signal just sneaks out. I used a paint stirring stick to mount to.

The options to power and use this module are so endless, it's well worth it. You could definitely put something together with ESPHome that would cost half the price, and that's what I almost did, but do you really want to spend hours tinkering rather than pay the extra $10 for a well-finished reliable solution that just works? In my particular case, I was trying to control an internal component of a hot tub that used 15 volts DC (what an awkward voltage), and using this module allowed me to power it directly from the same wires I was controlling, without the need for an external power supply. Super convenient. I also like that it has pretty much every integration under the sun, so I know that while I may want to control it directly with an app today, it will be able to connect to my Home Assistant instance in the future if I want more control.

Using two USB A power adapters and an e26 to 120 female plug adapter, I set this up to watch the power status of the garage door opener light to switch other outdoor lights on when activated. Wiring follows: Red/White: +5VDC from opener adapter. Black: -5VDC from opener adapter. Grey: +5VDC always on adapter. Green: -5VDC always on adapter. All others trimmed and taped off. The White analog wire connected to the Red wire allowed me to use the Voltmeter functionality to set up a trigger in Home Assistant when voltage was detected at the garage door light socket. I now have extra lighting when I come home in the dark and the other lights are also set to turn off and mirror the status of the garage. TP-Link, while their products are my go-to for price point and functionality, they don't report power status reliably. While this module has many features, the ones mentioned in this review made it extremely useful for getting a quick report in power status change, yielding useful light triggering. I didn't go through the trouble of adding a bleed resistor to the opener power adapter because I found a usb adapter that drained quickly after power off. There was some experimentation involved and I was lucky to have a generic usb adapter that met my needs. This functionality depends on how quickly any leftover charge is left in the adapter, so your results and implementation will vary from mine.

I love this little guy. I just made a tide Gage with a pressure sensor, using this to connect to Home Assistant, and it works like a champ.

Understand wiring diagram and device limitations. I fried 2 before using correctly. Don't think instructions are completely clear.

Il faut être ingénieur automaticien pour installer ce produit …

Exelente módulo,pero recomiendo que antes de usarlo investiguen bien sus características técnicas porque suelen ser un poco complicadas

o produto veio com defeito e ninguém respondeu a minha reclamação.

Excelente placa de Shelly para cualquier aparato que quieras domotizar, ejemplo una caldera. Capaz de poder programar y generar funciones para un uso autónomo y controlado con la aplicación móvil.

Lo Shelly Plus Uni è un modulo estremamente versatile e preciso. Facile da integrare nei progetti di domotica, offre letture affidabili e tante possibilità di utilizzo senza bisogno di hub. Come tutti i prodotti Shelly, anche questo si conferma una garanzia: li uso da tempo e non mi hanno mai deluso. Sempre top per qualità e affidabilità.
