## Description
ESP-SM6 is the 6-station hot-swappable module for ESP-ME3. It is the faster jump from a 4-station base toward the full 22-zone capacity — one bay, six new valves.
Use two SM6s plus an SM3 (4 + 6 + 6 + 3 + 3) or any other mix that lands on the station count you need. Modules seat with the controller live.
Sold as an ME3 add-on only. Wi-Fi is still LNK2; flow is still FG100 on the base unit.
