I've included the log file from the 3.4 firmware. It include's a print statement of the firmware version and both IT=1 and IT=0. As you can see the firmware happily continues running with either IT=0 or IT=1. Can't it be that the stricter timing in this firmware makes it ignore the 75us spikes in th...

I'm sorry, then it's indeed the other way around. I tried both IT=1 and IT=0. I also tried about every voltage level the thermostat still was responding to. I know it sounds strange, but with 3.4 it works. No error 01's at all. Diagnose.hex and 4.0a06 and 4.0a10 all report error 01 consistently or n...

One error=1 per thermostat message. When I enter It=0 i get nothing from the boiler anymore.

Funny thing is: i flashed 3.4 and that one works perfectly, burner on/off, doesn't matter.

Of course the new main board probably has even worse timings, nothing comes through again this time. Any ideas Schelte? (log included).

Just a very small update... Monday my main circuit board is being replaced under warranty because the display (two digits) stopped functioning. Schelte, do you want a log with timings of the new print? This is a nice way to determine whether it was exemplary or a pattern can be established. (BTW, yo...

This is called association and is supported by just about any Z-Wave dimmer or switch, either on the primary button that also switches the local load, or a secondary dedicated input button that supports it...

Hi everyone, I'm one of the developers of the Z-Wave binding for openHAB. I also started working on an Opentherm Gateway binding for the openHAB home automation system. (http://www.openhab.org). OpenHAB is a very flexible and powerful home automation system with extensive rule and scripting support....

It took even another try and I probably have the crappiest opentherm implementation in a boiler ever but it works now. Schelte, many thanks.

I'm more than thankful. I'l try it out today or tomorrow. Thanks!

I'm pretty sure that my thermostat has some problems already, because without the opentherm gateway, I rarely see the domestic hot water indicator on the thermostat. About 1 in 100 times I use the tap. Since i'm a software engineer, could you send me the assembly code? I might give it a try some time.

I don't seem to be able to add attachments, so i included the files in this post. What is immediately obvious is that with the burner on the intergas boiler seems to get out of sync with the clock signal or something. Some transitions are on roughly 700ms and 1200ms respectively. I am really curious...

It would be helpful if you could run test #3 of the diagnostic firmware while you recreate the problem situation (e.g. by running the hot tap) and send the output to me. I will then build a modified version of the firmware for you. Would you want firmware version 3.4 or 4.0a5? Sounds really good. I...

In this case rather bad... It's not an occasional message. The intergas heater does not produce normal messages anymore during the entire time the burner is switched on. over 90% of the responses is bad. Taking a shower completely destroys any communication between the boiler and the gateway. It is ...

I have an Intergas Compact HR heater that probably has timing issues on pump / burner start. It's mentioned in several forum threads, and the solution seems to be to relax the timings beyond the Opentherm specifications. The firmware that does just that (3.0.1) does not seem to be online anymore. Do...
