SONOFF SNZB-01 – Zigbee Wireless Button Switch; ZigBee Bridge Required; Batteries Included

These battery powered zigbee buttons are cheapest in the market (i.e. on Amazon) and support single click, double click and long press so can trigger upto 3 events using this small battery powered device. Ofcourse you'd need a compatible hub or a RPi with zigbee dongle though.

Could have been a little small in profile, but overall good product.

Easy to install ....

Please note, battery is not included with the product

Good

sharing my personal experience about this product. i bought this product from a different source and have tested it. We cannot use in Alexa routines. We can use it to switch On and Off Sonoff switches but their switches already work with Alexa directly and no need of additional button. So as per me, i did not see much of use of this button. And remember as of July 2020, if we need to use Sonff devices in IFTTT, we need to pay 10 USD subscription to upgrade to ewelink premium account.

Yes, Like other users pointed it out it is true if you plan to make this switch work with just an Echo Plus or Echo 4th Gen with built in Zigbee Hub and don't plan on buying the bridge separately let me tell you,you are in bad luck.After a lot of research I have found out that this sensor and some others were indeed supposed to work with zigbee built in echo devices such as an echo plus or the likes but because our region is india in the amazon app these devices will not work or even show up under smart home in routines section as these features are not made available to the indian users right now by amazon. Some devices do show up but will not work independently unless you change your amazon account to the US that is if you are not willing to wait.The other problem is the ewelink yearly subscription that costs $9.90 just so you can link your devices with IFTTT not to mention IFTTT itself charges rs430/month or $40 per year if you want to use applets more than 3.If you want to buy these devices either make sure you have a zigbee built in echo device with an amazon account of US region which is the cheapest of the other options or be ready to shell out more money on a Zigbee Bridge + ewelink Annual Plan + IFTTT monthly/yearly plan

Works only with IFTTT which is paid service.

Como ya han comentado, es necesario tener un hub ZigBee. En mi caso tengo Sonoff Zigbee Dongle conectado a una instancia de Home Assistant y funciona sin problemas.El botón es compacto, viene con cinta doble para montarlo en donde se quiera. Se puede configurar para un clic sencillo, doble o prolongado.

Fonctionne parfaitement sous Home assistant (Zha).

Portée assez réduite fonctionne quand même correctement avec une clé combee et home assistant, il faudra par contre appuyer plusieurs fois pour le réveiller et qu’il prenne en compte la demande d’allumage.

Come tutti gli accessori della serie se collegati bene a dovuta distanza svolgono il loro lavoro

Der Taster wird nach Gedrückthalten der Resettaste in der Phoscon-Oberfläche erkannt und funktioniert soweit. Zumindest 1x drücken und 2x drucken kann einprogrammiert werden. Langer Tastendruck hat bei mir nicht funktioniert. Preis Leistung ist top. Batterie ist auch dabei. Design ist nich meins / Geschmackssache
