I am proud to announce the release of firmware 3.0 for the espirp. Users can update their devices by going to the status web page of their device, and clicking the "OTA upgrade" button. But before doing so, read the information below for a few incompatibilities with firmware version 2.x. W...

That is something I never even considered. So I did some research. During normal use, the PIC will not write to EEPROM, So we don't have to worry about the 1,000,000 typical erase/write cycles. Aside from that I found estimates that the PIC should last at least 30 years. And more likely 50 to 200 ye...

Great that it's working fine now. While it is very unusual for a PIC to develop a fault like that, there wasn't much else that could explain the symptoms you saw. Unless you are right that your boiler causes interference and you don't see it now because the boiler doesn't need to heat the house at t...

When powered down, the boiler interface of the OTGW will present a high level on the opentherm line. A boiler should interpret that the same as no thermostat, or an on/off thermostat in off state. So, the boiler should not start heating. What happens to DHW depends on the boiler settings. There are ...

Why not? The forum doesn't charge anything for a new thread. I don't see how this is in any way related to the thread you posted in. Hijacking an old thread just makes your question more difficult to find in the future.

Maybe you can reveal what change you needed to make to get it working. That may help the next person that runs into the same problem and finds this topic.

As I mentioned, the esptool command (the one shown in step 6). But in the mean time, I have confirmed with Robert that you don't need to push the button with the GUI either. So, if just clicking the Start button on the GUI doesn't work to flash the Wemos D1 mini, you probably have a wrong setting. M...

So you have a Wemos D1 mini, not an actual NodeMCU? It doesn't really matter much, except that the Wemos D1 mini doesn't have a FLASH button to confuse you. On both devices you don't need it. The device can be put into flash mode via the USB interface, without any manual action. You should just be a...

The ESP easy firmware is general purpose firmware. As a result it has lots of settings you have to get right to work correctly with the OTGW. This is why the OpenTherm Gateway Manual provided by the Nodo Shop suggests to use firmware that was created specifically for the OTGW: https://github.com/rvd...

Yes they are. That's why I mentioned them in this topic. A WDT reset, like any other reset, always causes the processor to restart. Debug firmware 5.3.1 (which is what I think you are using) always resumes normal operation after a WDT reset, while the regular firmware would go into fail safe mode. T...

Firmware versions 6.1 (for PIC16F1847) and 5.4 (for PIC16F88) have been released to fix this issue.

Fail safe mode was originally intended for the OTGW to sideline itself in case of a calamity (indicated by a WDT reset), and allow the thermostat and boiler to operate as if the OTGW was not there. Obviously, this is only a reasonable strategy when there actually is a thermostat. So both firmware ve...

An overview of the addresses assigned to symbols can be found in the map file produced by the linker (dist/default/production/gateway.X.production.map):
byte1 0x000076
byte2 0x000077
byte3 0x000078
byte4 0x000079

Thank you for the detailed bug report and the extensive investigation. I actually ran into this issue myself a few days ago and I am working on a fix. When the OTGW is used without a thermostat, it sends a fixed sequence of messages. In this sequence there are also some slots reserved for user messa...

The code in qml scripts is basically Javascript. There are plenty of Javascript tutorials online. I have attempted to describe a lot of toon specific qml information in the DevelopingToonApps.pdf document.
