Restore last: (Button and Switch) - Configure Shelly device to Restore the last mode it was in, when it has power. If Device Name or Channel Name is set in the device, the integration will use them to generate the entities’ name. The time in milliseconds it takes for the light to transition and turn on to its set brightess or to turn off completely. FADE RATE
Connecting your Shelly to its cloud allows you to control it remotely, receive notifications and updates about your devices. The default for this setting is for the cloud to be enabled. If you disable the device cloud support, you will lose connection to your device from outside its local network! Actions Configure the actions for your device - enable, disable, add duration and URLs. Settings POWER ON DEFAULT MODE
Welcome
Both are compatible but I find the 2way give better control for dimming as up will dim up and down will din down. If Channel Name is set to the default value, the integration will use the Device ID and default channel name to generate the entities’ name, e.g. ShellyPro4PM-9808D1D8B912 switch_0. The integration uses Device Name to name its entities if the device has only one relay or no relays at all.
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 the following strategy to name its entities if the device has more than one relay: 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. If you think your Shelly devices are working correctly and don’t want to change your network/configuration, you can ignore the repair issue. Still, you must know you are giving up the best experience of using first-generation Shelly devices with Home Assistant. 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
Before proceeding with the wiring make sure you’ve identified the line, neutral, and load wires, and then turn the power to the circuit off at the breaker for safety. Hopefully, you can see from the diagram that I:
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 For my installation, I went with fig. 1 and this is my rudimentary wiring diagram for the Shelly Dimmer 2 and my Leviton switch: If Shelly devices are in a different subnet than the Home Assistant server, you should ensure communication on UDP port 5683 between these subnets. 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.
Smart Home Dimming with The Shelly Dimmer 2
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. I’ve been a fan of TP-Link (Kasa) smart home products for a while. They are inexpensive, allow local control, and work well. A couple of things happened recently that made me a little leery of TP-Link smart home products. First, at least for some European products, they announced they were removing local control of some smart home products. This makes them much harder to integrate with smart home hubs. After lots of complaints from customers, especially in the Home Assistant community, TP-Link offered a way to maintain local control. However, that makes them a little harder to trust going forward. If Channel Name is set in the device, the integration will use it to generate the entities’ name, e.g. Kitchen Light
