Orbit24632 B-hyve XD 2 Port Sprinkler Timer, Gray

Q: I have an existing 4 port faucet control with b-hye wifi device. do i need to buy another wifi device if i get the 2 port device?

If your existing 4 port uses a generation 2 b-hyve hub, your new 2 port will connect. That is both devices need to connect to Gen2. When I bought a new 2 port I thought it would connect to my Gen1 hub it won't. I had to go back an buy a Gen 2 hub separately
