SONOFF 4CHR3 & 4CHPROR3 4-gang Wi-Fi Smart Switch with RF Control

vsetko bolo v poriadku, doprava bola rychla, dobre balenie tovaru. produkt funguje presne podla mojich predstav, jednoduche ovladania a instalacia. super.

I specifically bought the PRO to replace 4 of the RFR2's that were a clutter under a table. This is so much better.

I am the biggest fan of Sonoff's devices that include the RF function so they can be turned off and on with a 433 MHz remote. And Sonoff's the only company that makes a 8 button remote for 433 MHz RF signals. I have nearly 50 devices installed in my home. Half are the TX/T2 series RF Wall Switch.

I do have one negative comment. The PRO could have been a lot easier to wire if they had continued to use the same wiring as is on the Basic or Dual. For that, I fault them, this is not easy to wire. But once it is, is perfect.

EwElink allows you to create a SCENE which is a stupid name really. It should be called "An automation" or "a macro" or something more indicative of a facility that allows you to take action for an event on one Sonoff digital device to another. So, I have already implemented this for 2 situations. 1. As I have a Holiday house with internet access, I can schedule the hot water system (and other things like the outdoor fridge and bug zapper) to turn ON before visiting. Sometimes when returning home, I forget to turn off the schedule so suddenly I am using expensive electricity for no good. So at home, on top of my bar fridge in the living room, (where I frequent often) I have a 4 channel unit as a Display ONLY with Scenes that activate a red light when a device is still ON (scheduled or otherwise). My workshop has a unit which can turn on an expensive soldering iron accidently. (Usually a bad ALexa command). I have added a Scene to this display as a precaution, (despite using "Inching" setting to turn it off after 50 minutes) to see if it has come on without my knowledge. So I have bought more 4-ch units to expand this idea. Big feature is Mains OR low voltage DC so it can be battery backed up or just away from dangerous mains AC voltages. Unfortunately, you cant use the 4 push buttons to do anything useful.

Like the LV input.
Like the independent dry contact outputs.
Like it only uses 1 Wi-Fi client.
Like the price.
Like that it plays nicely with Samsung and Google home.
Just needed some dry contacts to make my curtains "smart", and easy to operate from phone. Bonus was able to make them automatic at sunrise and sunset. Also linked it to a room light automation.
This piece of hardware opened up many options.
Have used the other outputs to automate my old air con unit.
Sorry no picture of a new box with many wires hanging out of it.
Now to my next project...

Great products. I have been using sonoff products for over 6 years and I’m really happy with result.

Me está funcionando muy bien pero he tenido el problema al configurar el wifi de que se ha puesto en modo RF al tener presionado el botón. Y ha dado la casualidad que un detector de movimiento ha saltado y lo ha acoplado al canal. Luego ha sido muy dificil desactivar el enlace con el RF. Las instrucciones para desacoplarlo no han funcionado. Y lo peor es que aunque lo he borrado de la app que se supone es como un reset de fabrica, tampoco ha funcionado. Ni con el reset se quitaba el RF. Al final he conseguido quitarlo pulsando el botón aunque no conforme las instrucciones y después de infinidad de intentos. Recomiendo desactivar los sensores de presencia mientras se configura este aparato. Por lo demás ahora funciona perfectamente. Gracias.

I bought this unit to control 3 central heating zones plus a hot water circuit. However, the software limits you to 8 'actions' maximum. So the most you can do is switch each channel on/off once per day. I want to switch each circuit two or more times per day but this is not possible. Also, there is no way to trigger two or more channels from a single action, they each require an individual trigger of which you are limited to 8.
Nice bit of kit but totally held back by the software!!!

Muito bom
