SEMP is an application-level communication protocol that SMA uses to bring household loads into its Smart Home energy management with the Sunny Home Manager 2.0. SMA groups SEMP with EEBus as a communication protocol, separate from communication standards such as Wi-Fi and ZigBee that carry the data. The list names Stiebel and Tecalor heat pumps, the AC ELWA-E, AC ELWA 2, AC•Thor and AC•Thor 9s heating devices, and Mennekes AMTRON wallboxes. Some AMTRON models need a minimum firmware version, such as 5.22 or 1.3.45. Miele appliances in Miele@home do not use SEMP. The Sunny Home Manager talks to them over Miele's own Homebus protocol instead. SMA does not expect to add more SEMP devices, because EEBus, which covers the same functions, is becoming the industry standard. The SEMP protocol description is available to integrators on the SMA Developer page, under on-site integration.
