Nefit praat geen opentherm. De gateway zal dus niet werken.

It seems the answer is bit more complicated nowadays.

According to Nefit:

"Kan ik een Open Therm thermostaat aansluiten op mijn Nefit ketel?

Ja, afhankelijk van het toesteltype kunt u een Open Therm thermostaat gebruiken voor uw Nefit HR-ketel. Raadpleeg de Nefit Dealer voor advies, of bel met Nefit Consumentenservice."

nefit.nl/consument/service/faq/veelgest ... lde-vragen

It seems some of their devices can be connected to an OpenTherm converter, which is available for about 60 euro.

Not sure if it will work in combination with an OpenTherm Gateway. Your mileage may vary...

Come on guys.. no pain, no gain :wink:
And if the conclusion is that the gateway doesn't work with your equipment, I'm sure you can make some other member (who doesn't like to solder the gateway himself) very happy with it. I think I even saw someone asking for that...
So I don't think it will be a waste to just try.

Granted. But a Nefit boiler with a Nefit thermostat like jakkes has? I give that a very low chance of using Opentherm.

The opentherm gateway doesn't have any use for a serial interface on the boiler. The serial interface on the gateway is for communicating with your PC.

My post was more in general, not specifically for jakkes; I see posts like "if it works in my .../with my ..." more, not just in this topic.

@Rutger: I've added you to the list. PM received.

It seems that we have made it for this batch as well: there are 7 members who've pledged to pay for a board. I'll order this batch and contact people in this batch for payment and shipping info. Still 2 boards left in this batch for those who need one.

sorry i could have told you that!
i have been fighting with Nefit for years now to open up the protcol!

I am replacing my 5 year old Smartline hvac soon for a Remeha Calenta 40C :-)

Anybody who knows a cheap address for a Remaha Calenta 40C including installation.
I now have a simular Nefit smartline HR, so replacing is not that much work

Hi all,

To maintain an overview of pcbs, payments, etc. I've created this summary of the several pcb rounds, their status and their participants. I will keep it up-to-date.

If you're a participant, please review the information below and inform me of any errors you may spot.

The status following your name can be one of these:

[OK] = Payment received, address received, all cleared for immediate shipping after reception of the pcbs.
[Awaiting payment] = Info has been sent (PM or e-mail), but payment and address have not yet been received.

If your personal status is [Awaiting payment], please take care of it, as instructed by my PM or e-mail. If you didn't receive the info, please send me a PM or e-mail (or reply to the topic, if you have no other means).

Please note: with all these concurrent batches, I might decide to reorder the lists according to payment status. In that case, a paying member in a later batch might take the place of a non-paying member in an earlier batch. This is to prevent me from being stuck with a stack of ordered but unpaid pcbs.
