Up until last weekend, the OTGW worked fine. Last weekend, I wanted to test my electrical installation, which also cut the power to the gateway. Afterwards, the problem I stated returned. Since I suspected an electrical fault, I decided to order a new gateway from NodoShop (revision 2.13), to get ri...

You were right that cutting the reset line would not solve anything, as a few days ago the problem occurred even without it being connected. (I had the NodeMCU connected via wires instead of plugged into the board) Today I did the following things: Added/reflowed some solder on the power supply side...

I will try some of your suggestions later this week, thanks! The power supply was previously set to 20V, but I had already set it to 24V during this testing. With my multimeter I see that it outputs 22V under load. What kind of capacitor should I use? I have some 25V lying around, which seem appropr...

Thank you very much for your detailed response! I finally got around to testing some things. Unlike I said previously, just resetting the PIC does not always trigger the problem. Although it does happen sometimes, it happens more when the NodeMCU is reset, even with the code for resetting the PIC tu...

After running OTGW succesfully for several years, I have run into some issues recently after switching my thermostat from a Honeywell Round Modulation to a Honeywell Round Wireless RF (Y87RF2008). This new thermostat sometimes jumps to it's maximum setpoint of 35 °C. (If I lower the maximum temperat...

Great to hear!
This coincides with my experience, that it only seems to occur when both the PIC and ESP boot at the same time.

The firmware I was running was a program I made myself in the Arduino IDE, as I wanted to combine it with something else.
Adding in a few statements to assert and release the reset line via GPIO 14 seems to have fixed the problem.

Thank you very much for the help and the pointers to this direction!

Thank you for your response. When it works, I receive '19D=90'. Unfortunately, the debug output is not available after a power-cycle. I guess it is not possible to trigger a debug flag on boot, or via a GPIO? Removing power from the PIC and then powering it again seems to be the most reliable method...

I have a problem with my OTGW that I cannot seem to figure out. My OTGW PIC does not seem to respond to any commands received from the serial input... sometimes. Serial output works fine. Running otmonitor I get regular updates from my thermostat and boiler. However, sending a command such as PR=A d...
