The maximum range between the SwitchBot Hub Plus/Mini and SwitchBot Bot ( hereinafter referred to the Bot) is 80 meters in the open field. The distance is shorter in house depending on specific radio environment and walls in between.
The distance between any 2 SwitchBot Bluetooth (BLE) device (e.g. one Hub to one Bot, one Bot to another Bot) is 80 meters in the open field. Once BLE mesh feature enabled, the signal from device A will relay one by one automatically to reach device B even out of the 80-meter range.
