Here are the instructions for setting this bulb up using the Alexa App: Works with Amazon Echo Plus Open the Amazon Alexa app. Select “Add Device”. Select “Light”. Scroll down the light brand list to select “other”. The LED bulb will connect to Alexa by clicking “DISCOVER DEVICES” (ensure the light is on and in a pairing mode). Set up the device and the “light bulb” now is ready to use. Name and control the bulb.
Puddles, I presume you are asking about the frequency used by the remote to communicate with the bulbs. It is 2.4 GHZ. I have a picture of the back of the remote posted below.
From the product description: Bulb can be controlled with included remote or with your Zigbee Echo Plus and SmartThings Hub That said, I find the following: Get some peace of mind with Ring and SmartThings. When your Ring Doorbell button is pressed or motion is detected, SmartThings can send you notifications or trigger lights or alarms of your choosing. The process seems pretty straight forward: Connect the Ring Doorbell through the SmartThings app In the SmartThings mobile app: From the Home screen, touch the Plus (+) icon and select Device Select Ring and touch Doorbell or Camera Choose a Location for the device Choose a Room for the device and touch Next Tap the field that says Tap here to enter your Ring credentials Enter your Ring account email address and password Touch Next and select Authorize All Ring Doorbells associated with your Ring account will be automatically selected If you do not wish to add a particular Ring device to SmartThings, tap Use these Ring Devices and deselect that device Tap Done to complete setup
You need a hub.
Yes, I use Samsung SmartThings to control everything
