 ### Relay mapping
 
-After a restart the ARM firmware starts to scan for available 4Relay modules. Every module has a unique id which is send to Tasmota in random order. For a user to pinpoint a physical set of four relays it is therefor needed to "map" the scanned modules once. Tasmota stores the id's in a mapping table build using the command ``SspmMap <scanned module number>,<scanned module number>,..`` where the first entry will map to physical relays 1 to 4, the second entry will map to physical relays 5 to 8 etc. The scanned module information needed is displayed on the console during restart or on request by executing command ``SspmScan`` with a ``weblog 2`` setting.

     Scanning takes over 20 seconds so be patient
