 Some settings can be defined (defaults) at compile time by setting the following defines:
 
-MULTI_RELAY_HA_DISCOVERY true or false
+```cpp
+// enable or disable HA discovery for externally controlled relays
+#define MULTI_RELAY_HA_DISCOVERY true

 The following definitions should be a list of values (maximum number of entries is MULTI_RELAY_MAX_RELAYS) that will be applied to the relays in order:

-MULTI_RELAY_DELAYS 0,0
-MULTI_RELAY_EXTERNALS false,true
-MULTI_RELAY_INVERTS false,false
