Shelly Dimmer 2 - Twin Pack

Tiny WiFi dimmer, sits happily behind the existing on/off light switch, allows the switch to continue to work to control the light, easy peasy connection to WiFi and configuration via the app, works great with Alexa. The only advice I'd offer is to run the dimmer calibration routine in the app - my light fitting gets 100% at about 60% of the dimmer's supply, so calibration takes care of the discrepancy. The only downside I've found is that it takes a few minutes to reboot and reconnect to WiFi if any defaults are changed from the app. Can't recommend it enough though!

Great item. You must allow autoconfig in software to stop it overloading and cutting out. Once you've autoconfigured its brilliant, I've had two in use for over 6 months no problems. Works with both google and alexa

I bought these to enable me to make all the lights smart in part of my home, I've got 4 of them all connected and are all reliable and operate of multiple switches. The ability to connect to home assistant is great too as I'll be able to set them to come on automatically with other smart devices. The dimming function is reliable and don't flicker like normal dimmer switches, they are very customisable in the app.

These devices are grate but as others have noted I couldn't stop my bulbs from flickering even on full brightness. To be fare I didn't notice until my wife pointed it out and she was affected by it more than me so I have changed to a non dimmer shelly. I also lost connection after the first day, had to factory the unit but it kept doing the same thing. I would of just replaced it if it hadn't caused the lights to flicker. My bulbs say Leading Edge so I tried both settings in the shelly but that didn't help, they were also more than enough watts according to the shelly PM.

I have a number of these relays including other types as well but recently I've had nothing but trouble with the dimmers. This is why I haven one star off. About 2 months ago, I ordered a 2 pack but didn't test them immediately as I have many shellys and they've all been rock solid. Anyway, when I eventually came to do the installation, one of the devices was dead. I contacted amazon, as I had missed the return window, and they were kind enough to do a full refund. I then immediately ordered another set and this time I tested them right away and both were working so I was happy. Unfortunately, after the installation in 2 bedrooms, I could hear a high pitched buzzing sound coming from the relays. The noise is especially loud at night. See the video. You have to turn the volume right up in order to hear it. This was done with only a live and neutral wire connected, no lights or dimming lights. I had to take them out and install physical switches for the time being. I will be returning this set and will order another one. I hope I've just come across a bad batch as this is really annoying!

DANGEROUS FIRE RISK, nothing but issues. Two of these Shelly dimmers out of a batch of 4 burnt out shortly after the 2 year warranty expired. The cases are charred black. A google search for “shelly dimmer burnt out” brings up hundreds of complaints of the same problem. The main house MCB blew on one. The circuit board soldering is substandard, and has developed a direct short between live and neutral on one, the other has melted terminals. They could have caused a fire. The functionality of the dimmers is also very poor, the wifi disconnects frequently, the calibration resets repeatedly, they cause interference noise on speaker systems in the house and clearly the overheat safeguard doesn’t work. These were installed on lights less than the specified load per the instructions. Shelly have refused to acknowledge the issue, the seller was initially helpful, but hasn’t offered a refund or returned the faulty dimmers to me. Dangerous product. Should be recalled. Of a mind to report to trading standards.

The seller is very prompt in shipping and it came the very next day. The product is 100% real. Knocked off 2 stars because it doesn't work with my expensive LED lights with in built drivers. There are flashes of light at regular intervals even at 100%.

Not sure if I just got a faulty batch, but I’ve had nothing but trouble with these. I did a lot of bench testing to make sure it would work for my application with a test lamp, after much faffing I ditched the app almost entirely as it just wouldn’t register that the dimmer was online, yet I could see it connected to my router. Instead I accessed directly with the IP address. I got to a point where I was happy enough with it on a bench (had built some automations with home assistant to get it to do exactly what I wanted) and then fitted then to the lights. About 2 hours of effort, and they lasted 1 day before I swapped them back. In that one time, I had to power cycle them every hour. They would randomly just disconnect from my network, then the only way to reconnect was to flip breaker off and on. Both units were updated to the latest firmware while bench testing. Unfortunately im about £100 into this overall (including momentary switches etc) and it’s just not worth the hassle. I had heard good things about Shelly and this was my first dip in. Won’t be back for a while! Your experience may vary, and the reviews do suggest contrary to what I’ve had happen. Maybe I’ve got a bad batch or something. But it’s too late to return unfortunately. Steer clear until there’s a new version and they’ve ironed out the kinks I think.

Ottimi come prodotto e affidabili come funzionamento. Arrivati nei tempi

J’ai passé plusieurs heures à essayer de le connecter le Shelly dimmer 2 sur le réseau wifi de ma maison. Sans succès aucun. Étant donné que j’ai créé un réseau wifi 2.4 GHz spécifique qui supporte déjà plusieurs objets connectés, je pense qu’il y a soit un bogue dans la version IOS 14 de l’appli de Shelly, soit les deux dimmers sont fautifs (pas de mis à jour ? Date de l’emballage 2019). J’ai essayé deux procédures différentes pour la connexion décrites dans une vidéo de Shelly et dans le guide d’installation contenue dans l’emballage, sans que rien marche. Je l’ai donc retourné à Amazon.

Unfassbar gut zu einem sensationellen Preis vergleichbare Dimmer kosten sonst ein vielfaches und die Programmierung war auch nicht besonders schwer. Sogar über Alexa kann man das Licht an und aus machen und auch dimmen. Klare kauf Empfehlung und ich habe mir gleich noch zwei Steckdosen Stecker gekauft

Hatten versehentlich zu starke Leuchtmittel für unsere Esstischlampe gekauft. Dank diesem Dimmer müssen wir jetzt abends nicht mehr mit Sonnenbrille das Abendessen genießen 😂👍🏻 Steuerung über die App und den Browser funktioniert hervorragend.

Sono una figata!!!
