Re: No reply from USR-TCP232

Thank you, that is helpful in case I run into any issues. It has now been running correctly for 2 days without needing any intervention. The parameters already worked, so the fact that I don't have the password is not an issue for now. In these 2 days, I have finally experienced 0 losses of connecti...

Re: No reply from USR-TCP232

Well I just found out that it's already configured correctly and it already works in the system. The password seems to have been changed too. I guess I won't need that for now. However, if anyone could tell me what it might be, that would be appreciated.

Re: No reply from USR-TCP232

Thank you! I've just retried with both a Linux and a Win PC, but still no success. I followed the instructions in the Nodo Opentherm USR-TCP232 quick start guide, which says to configure a fixed IP on the PC of 192.168.0.201 with subnet mask 255.255.255.0 and gateway 192.168.0.1. Then to browse to h...

No reply from USR-TCP232

Hi all, For about 4 years now, I've been using the OTGW to control our heating, using RPi temperature sensors in a few different rooms. It behaves much better than the original thermostat, so I consider it a success. The one thing that has always bothered me, is a frequent loss of connection over Wi...

Re: External control timout - proposed solution

Again thank you, hvxl Today the boiler does get active when a higher CS is requested. FYI, there is indeed an outside temperature sensor. And I had indeed set the CS request 20 °C higher than the current boiler water temperature. I will start working on the control system now. If it should run into ...

Re: External control timout - proposed solution

A big thank you to hxvl! The timeout works. I corrected my mistakes as posted below for the sake of anyone who would like to use this. All the lines with "Wim" in the comments are additions. It reports that it builds successfully but the build.vbs produces an "invalid root in registry...

External control timout - proposed solution

Hello forum, I would love your feedback on the proposed code below. I am not a coder though I have done some coding, so a critical look would be much appreciated. The purpose is to have a 5-minute timeout on the CS command. That means: a CS command only remains valid for 5 minutes. After that, it is...

Re: Modification of firmware

marcelr, in the interest of reliability I would much rather have the OTGW handle everything. I don't trust the setup enough to send every single message through the Pi. The Pi would only have to request some values and send a CS command. In case the Pi stops updating the OTGW, the gateway should can...

Re: Modification of firmware

Hello guys, I searched the forum for results on this, but could not find any. Could one of you report? antst is asking about exactly the kind of thing I'm working towards: an external device (probably a Pi) instructing the OGTW to modify the boiler water setpoint (CS) with an automatic fallback to n...
