Your timezone and location will be autodetected, but you can manually change them from this setting by choosing a timezone from the drop-down menu and typing in your latitude and longitude. There is also a button Auto detect location, which will make the device automatically detect the location once again if it failed the previous time. DEVICE NAME The integration uses Device Name to name its entities if the device has only one relay or no relays at all. Also, the Shelly Dimmer 2 is really small. Even smaller than the Shelly 1 relay. Shelly Dimmer 2 next to a quarter Shelly Dimmer 2 installation

Connected Line/Hot to an L input on the Shelly (I don’t think it matters which of the three L inputs you use, but I chose the middle one). With conventional dimmers, you can only have one dimmer in a circuit if the lights (or set of lights) are being controlled from more than one location. Auto on: After turning off, the relay output will be automatically turned on after a predefined period of time (in seconds).Shelly Plus 1: http://A.B.C.D/ota?url=http://rojer.me/files/shelly/shelly-homekit-ShellyPlus1.zip Note: The Shelly must have installed 0.10.0-beta3 or above to be flushed, please update first! As with other Shelly devices, this Dimmer 2 can be controlled remotely via a few different APIs, including REST and MQTT. The device can also be controlled via its internal web server or via the Shelly app (locally or in the cloud). Also like other Shelly devices, enabling MQTT disables cloud control. Some of the key features include the ability to set a minimum brightness level, fade rate, scheduling, timers, and triggers to call other smart home devices (Actions). from what I hear having a neutral to the ceiling rose would be preferable, how hard would this be for my electrician to run now that everything’s has been plastered? If you are switching from two locations, you also need to use 2-way switches for both the plain switches and dimmers (many dimmers are 2-way compatible). You can only have one dimmer on the circuit.

Using retractive switches for dimming is dependent on the type of LED driver that is used. Not all LED lights can be dimmed with just the switch. If the drive states “Switch Dim” then they normally use retractive switches for control.

Welcome

Detached: (Button and Switch) - Set Shelly device to be in Detached switch mode - switch is separated from the relays. outdoor lights controlled from two locations (i was hoping to have simple on/off 2 way retractive switches) do I need anything special from the switches in terms of set up? There are two generations of devices. Both generations are supported by this integration. There are some differences in how devices should be configured and in the naming of entities and devices between generations. Shelly device configuration (generation 1) This setting makes your Shelly device discoverable to other devices such as your mobile phone or PC. CALIBRATION

shellies/command which can be used to send a "broadcast" command to all devices on this MQTT exchange I decided to replace it. It controls the light fixture in my bathroom, which actually has dimmable lights, so I thought, why not replace it with a smart dimmer? As much as I’ve liked TP-Link products, I’ve loved Shelly products even more (for my garage, my fireplace, my light switches, flood sensor, smart switches, smart bulbs, etc.). Enter the Shelly Dimmer 2! Shelly Dimmer 2 specs and featuresAuto on: After turning off, the relay output will be automatically turned on after a predefined time (in seconds). The configuration of the MQTT component contains information about the credentials and prefix used and the protection and notifications settings of the MQTT connection. Property Home Assistant has a native Shelly integration, but for some reason, it didn’t work with the Shelly Dimmer 2. I received an error message about the Shelly being on an unsupported firmware version. It probably will be fixed in a couple of releases. No worries though. You can integrate with the Shelly via MQTT right now. First, you need to set up an MQTT broker and integrate it with Home Assistant. I’ve explained what MQTT is, how it works, and how to set it up in Home Assistantso I won’t repeat it here. Set up MQTT on the Shelly Dimmer 2

If Home Assistant is running as a virtual machine or service on an operating system other than Home Assistant OS, you should open UDP port 5683 on the device’s firewall and/or ensure that communication from this port is redirected to the Home Assistant service. Next, you’ll want to set up the way the Shelly reacts to buttons. I’m using a two-button switch, so I set it up accordingly in Settings->Button Type: I have come across an issue with using these switches that needs some clarification as I’m new to buying these switches in that the apparently to use the 3 position switches to turn on and dim on their own would not allow this functionality alone and must be used with LED fittings (I assume this mean LED dimmable bulbs) or drivers that have the switchDIM functionality? Can anyone clarify what these drivers are? Or whether I would need them if I installed a Shelly dimmer 2 If you can’t find the CoIoT peer settings in the device’s web panel, it’s probably using an ancient firmware version, and you should update it to the current one.Restore last: (Button and Switch) - Configure Shelly device to Restore the last mode it was in, when it has power. I prefer to not have a cloud connection, and I want to be able to automate my fireplace based on other factors in my home. The Shelly app and interface allow for some automation, but I prefer to use Home Assistant, my favorite automation controller. If the BUTTON TYPE of the switch connected to the device is set to momentary or detached switch, the integration creates an event entity for this switch. You can use this entity in your automations.
