Nefit OpenTherm

The Nefit Proline talks OpenTherm and can be connected directly to Adam/Anna.

Nefit EMS

Most Nefit boilers work with EMS. Plugwise sells the Nefit EMS-OT converter to be able to talk OpenTherm to Adam/Anna: Nefit EMS OpenTherm converter.

Nefit Ecomline

The Nefit Ecomline talks an older Nefit protocol called iRT. With two adapters it is possible to convert this to OpenTherm to communicate with the Ecomline:

Ecomline Boiler <iRT> Nefit EasyControl adapter <EMS> Nefit EMS-OT Converter <OpenTherm> Adam/Anna

Plugwise sells the EMS-OT converter to be able to talk OpenTherm to Adam/Anna: Nefit EMS OpenTherm converter.

Plugwise does not sell the Nefit EasyControl adapter. This can be found online under the name "Nefit EasyControl adapter" and "Bosch EasyControl adapter".
