Re: Missing Values

You have to enter some UI commands to give the OTGW some opportunity to send the IDs you added as alternatives. It doesn't matter if you do the AA commands first, or the UI commands. I'm sorry, I can't explain it any better. It's not that complicated in my mind. But that may be because I know how I ...

Re: Missing Values

As explained on the web site, the OTGW takes advantage of messages the boiler does not support to obtain additional information. The OTGW learns which messages the boiler does not support by looking for Unknown-DataID responses. At least in the short piece of log you provided, no Unknown-DataID resp...

Re: Missing Values

This indicates that your boiler is able to provide more information than your thermostat is requesting. You can instruct the OTGW to request this information for you instead, using the AA command with the message IDs for the relevant parameters: AA=28 Return water temperature AA=26 Domestic hot wate...

Re: Open Therm Gateway PCB in parallel over the PCB of the Evohome

Opentherm is a point to point protocol. So you cannot connect things in parallel. But you can use both an Opentherm thermostat and the OTGW by connecting them in series. In case of the Evohome thermostat that means: Connect the cable from the boiler to the boiler connector of the OTGW. Then connect ...

Re: OTWG hangs up

Your description is much too vague to be able to provide any useful suggestions. You say the LED stops blinking. But the link shows the green LED blinking all the way to the end of the video. The video also shows that no thermostat is connected to the OTGW. Without a clear description of the problem...

Re: Geen firmware upgrade mogelijk

Op een originele "Rev. B" printplaat zitten geen ledjes. Er kunnen wel leds worden aangesloten op de "LEDS" eilandjes. Deze zouden ongeveer een seconde nadat de stekker van de OTGW in het stopcontact wordt gestoken even een keer moeten flitsen. De troubleshooting web pagina geeft...

Re: Geen firmware upgrade mogelijk

Dat klinkt alsof er een communicatieprobleem is. Ik adviseer om dat eerst te onderzoeken. Als de communicatie niet goed werkt, gaat een firmware upgrade waarschijnlijk ook niet lukken.

Re: Infrequent room temperature measurements

The OTGW reports the information it receives from the thermostat and boiler. It does not make up values or report old data. So it must be that the Lyric T6 is reporting the same temperature for long periods of time. I have no idea why a thermostat would do that. Sometimes battery powered RF thermost...

Re: Remeha Calenta Ace met een E-Twist foutmelding 03

Je bent je er hopelijk wel van bewust dat een kale eTwist (7672429) alleen het R-bus protocol spreekt. Dat werkt met een Remeha Calenta Ace, want die begrijpt dat ook. Maar de OTGW ondersteunt alleen het Opentherm protocol. Daarvoor heb je een eTwist met gateway (7648242) nodig. Als je al een losse ...

Zo nu en dan een Error 03 kan geen kwaad. Zolang het maar geen honderden per uur zijn.
