While dual mining uses some of the hashing power to mine Ethash coin (e.g. ETH) and some of the hashing power to mine the second coin of a different algorithm (e.g. SMART), the merged mining mines at two blockchains with the same hashing power at the same time. And while dual mining happens between two different algorithms (Ethash and another), merged mining is possible only for coins on the same algorithm.
Merged mining coins you can monitor and add to profit switch on minerstat:
To set up merged mining, you will need to find the pools and coins that support it. The set up of merged mining will be similar to regular mining setup, but you will probably identify with your username instead of wallet address and the pool ports will be different. Each pool has its own config definition you will need to follow.
When you are setting up a profit switch, you can also add a merged mining option. Merged mining coins will be selected only if this is the most profitable options between everything you have set up. To enable merged mining for profit switch, you need to:
