No. SwitchBot automatically selects the nearest SwitchBot Hub (Plus) in the 1st time paring (by enabling any of Alexa, Google Assistant or IFTTT). It always uses the paired Hub (Plus) then.
If you have multiple Hubs, and your SwitchBot is always not reachable via the Internet (e.g. when Bluetooth temporarily disabled, or voice control), try unpair your SwitchBot from the App Device List, and pair once again.
