Actually this device will only connect to three audio devices such as speakers, headphones, or amps. It will also connect to 22 Bluetooth Low Energy (BLE) devices such as plugs, and switches. The compatibility list for BLE of this device does not include Z-Wave or ZigBee devices. If you are interested in using it for remote controlled devices, I would recommend looking at the devices you want to use before purchasing this. Samsung’s Smart Thing, and Wink’s Hubs are much cheaper and IMHO have a better group of compatible devices. Both of the later also work well with Amazon’s Alexa. I have Version One of the Wink, with 18 plugs/switches and have been fairly happy with it.
This device’s listing also indicates a clear distance range of 1000 feet. However, as near as I can tell this is for the BLE devices. Until Bluetooth 5 devices come out on the market, it is unlikely you are going to get more than 40 or 50 feet of room to room range, unless you are really lucky.
Recently I purchased a second multi-point Bluetooth transmitter (See post above for the first) from EBay for less than $15, including the cost of shipping.

Hooking two of these up to an Amazon Echo Dot, with a 3.5 mm hub has provided four audio connections. All provide good sound quality and do not have any noticeable latency (lag). I might have gotten lucky as all four of my output devices’ receivers are different brands. Having the same source and brand transmitters is more critical. For instance do not try hooking up two or more of these transmitters to different Direct TV boxes, as the latency between them can be measured in seconds. Having most of the household filled with the same surround sound, especially when you move around, is awesome. Everyone that has heard it has said WOW!
Even though I have Bluetooth Version 4 on both the transmitting and receiving end; microwave interference is still a problem. This problem might be a little worse for me as my microwave is mounted high and on an interior wall. If you plan on putting a speaker near or in the kitchen this will likely be a problem for you as well. My microwave’s range of interference is about 15 to 20 feet. This problem might be less or more depending on the shielding, power and location of the microwave. If you have a party you can count on the microwave being run, even if you do not expect it will be run. As Murphy will confirm, this is how the world operates.
