Nefit ProLine NxT + Nefit ModuLine 1010

Hello,

I've recently received my OTGW from Nodo-Shop (firmware 6.0, PIC16F1847) and I've attempted to set it up between my Nefit ProLine NxT (boiler) and Nefit ModuLine 1010 (thermostat). Per compatibility matrix, only the boiler was supported, but I thought I would be lucky.

Unfortunately the thermostat does not seem to be compatible, even though allegedly it should be per manufacturer documentation. Let me separate some tests that I did:

Boiler + OTGW: works, I see the periodical messages of the standalone mode and can use it to read data from the boiler and actually control the control setpoint.

Thermostat + OTGW: I don't know what happens here. After I plug the thermostat the gateway reports Low power and stops the periodic Read-Data messages. About 1 minute afterwards the thermostat reports error code A61 1008. Per manual, this should mean that OpenTherm communication failed, so I deduce that the thermostat should be OpenTherm enabled (allegedly).

Thermostat + OTGW + Boiler: Output from the gateway seems to be the same as if only the thermostat was connected, with the added change that the boiler flame turns on and off periodically.

I'm not entirely sure how to debug it from here. I wish I could provide some logs that show messages flowing through, but I couldn't get the thermostat to actually communicate with the boiler while the gateway was connected, even with monitor mode enabled. I've tried to work through different reference voltage levels without much success.

Edit: Ok this is very weird. I've flashed the diagnostic firmware and test 2 had actual messages being read, which left me wondering what was happening before the flash. I've then flashed the normal 6.0 firmware and now I see the messages flowing through. I now wonder if the original firmware was an old revision (even though it did say 6.0).

Just to be clear: If a boiler or thermostat is not listed in the equipment matrix, it doesn't necessarily mean that it is not compatible/supported. It only means that nobody has uploaded a log from that device yet.

A famous adage says that "a picture is worth a thousand words". But if it's just a picture of text, then providing the actual text would be more useful. Anyway, the picture shows that the thermostat sent a few Opentherm messages. But because no boiler was connected, it didn't get any response. The thermostat seems to be capable of using a few different protocols. When it didn't get a response, it may just have given up on Opentherm communication at that point. When you later connected the boiler, it may simply not have tried again to initiate Opentherm communications (I'm just guessing here).

Trying the diagnostic firmware is exactly something I would have suggested. So you did know how to debug it! I'm glad that you got things working that way.

The OTGW with PIC16F1847 is a fairly new development. Version 6.0 is the first and only firmware released for that PIC. Development versions would have identified as 6.0a1, 6.0a2, etc. So, if it said 6.0, you had the correct firmware.

I noticed an interesting remark in the thermostat manual: "De bedieningsunit is niet geschikt voor het regelen van warmtebronnen met BUS-systeem OpenTherm van andere fabrikanten" (The control unit is not suitable for controlling heat sources with BUS system OpenTherm from other manufacturers). I wonder why that is. It might be interesting to see a log.

So...the plot thickens. I've been iterating with reboots and plugging cables in and out in order to see what happens here. I actually found a way to consistently connect the thermostat:

1. Start the gateway with only the boiler connected. It will default to gateway mode and start doing the standalone-mode command sequence.
2. Move the gateway to monitor mode.
3. Plug the cables for the thermostat. At this point I see in the logs:

Code: Select all

10:07:02.465088  Medium power
10:07:30.882678  Low power
10:07:30.991605  Error 03 (between 0 and 2 times)
At this point the thermostat did what I call the 'connect dance' and actually works - if I edit the setpoint on the physical thermostat I see the control setpoint being edited and hear the flame turning on. With that being said:
4. If I move now to gateway mode, the gateway itself does not recognize the thermostat, and it starts doing the standalone-mode command sequence.
5. Instead, if I press the reset button on the gateway, on the next boot the gateway correctly detects the thermostat and everything works even in gateway mode. I can reset as many times as I want from this point forward, but if I unplug the USB cord, I need to start from 1 again.

I start to think that this thermostat is 'dual-mode' between OpenTherm and EMS 2.0. Maybe what happens is that it first tries to connect using EMS 2.0 ?

That would explain my 'race condition' experience - if this initial dance between the thermostat and the boiler occurs while the gateway is booting up (i.e. while it is in de facto monitoring mode), then I don't need to do anything, because the weird EMS 2.0 related things occur while the gateway doesn't have to process them. But if the gateway boots faster than this hand shake, I need to do the whole monitor-unplug-reset process.

Any thoughts on this ?

I guess this is what they meant when they indicated that the thermostat is not suitable for OpenTherm equipment from other manufacturers.

The logs show something quite unusual: Boiler responses without requests. Probably the requests are somehow invisible to the OTGW. It doesn't report any message, but it also doesn't report any error. So it seems like the thermostat sends requests using one protocol and the boiler responds using another protocol (or multiple protocols?).

You may be able to get more details about the communication by first starting test 2 of the diagnostic firmware and then connecting the thermostat. Then repeat the same procedure with test 3. But even with that information it is probably going to be difficult to figure out how to convince the thermostat to talk Opentherm after powering on the OTGW.

The responses (Read-Ack without Read-Data) seem to be a side effect of the thermostat connection before the PIC is reset. Take a look at this minified log:

I thought that the thermostat will be the one with non standard behavior, but during diagnostics it seems that the boiler has some weird voltages/timings.

I also expected something very different from test 2. Somehow the thermostat detects a difference between the diagnostic firmware and the gateway firmware in monitor mode. I don't have a clue how that is possible. In both cases the comparators are configured to pass through the signal unmodified. I have no ideas how to continue from here without specialist equipment.

That's fine, thanks a lot. I don't have any ideas left for now either and also this thermostat is very basic, I cannot even override the temperature remotely as it does not implement the temperature override reading. Since the standalone mode seems to work fine with the boiler itself, I'll probably toy with that in the meantime.
