Nefit easy connect adapter vs. EMS-OT converter

Postby marcelr » Thu Mar 10, 2016 10:31 pm

I have a toon thermostat talking to my nefit topline boiler through toon's boiler module, Schelte's OTGW and nefit's EMS-OT converter. To test some toon software, I would need another EMS-OT converter to emulate an OT-compatible boiler. Now the Nefit easy connect adapter has entered the market. It's a lot cheaper than the EMS-OT converter. As far as I can see, it does exactly the opposite of the EMS-OT converter, i.e., receive EMS commands, translate into OT, and transmit to a connected boiler, whereas the EMS receives OT, translates into EMS and transmits.

But I'm not sure.

Two questions:

Am I correct that easy connect does the opposite of the EMS-OT converter? Some other thread here (viewtopic.php?f=75&t=9355&start=0&hilit=nefit+easy) is a bit confusing.
If so, can the easy connect adapter be used in reverse? Feed it with OT commands at the OT-side, and make it spit out EMS at the other end?

Alternative suggestion: If you load the interface firmware on the OTGW, you can create your own responses and emulate any boiler you want that way.
