This is probably not the best topic to use for asking that question. However, the Opentherm Gateway will work with almost any boiler that communicates via the Opentherm protocol. The thermostat is the more determining factor of how much you can control via the gateway.

If your question is if Buderus boilers are likely to be using the Opentherm protocol, then no. Buderus is a US company and Opentherm doesn't appear to have taken off in the US yet. After a little googling I understand there is supposed to be an Opentherm converter for Buderus boilers. But if you have not specifically ordered that, the boiler probably doesn't communicate via the Opentherm protocol.

I'm trying to get the script up and running also.

All devices are created but not updated.

If i run the ps=1 command i'll get:

18-10-2012 19:50:53 - debugOTm - Response from Serial Port: T10012800BD0012800
18-10-2012 19:50:54 - debugOTm - Reply:

And then, nothing.

IF i run ps=1 from putty:

00000011/00001010,40.00,00000011/00000011,0.00,0/0,20.50,0.00,0.00,20.52,39.20,0.00,0.00,0.00,60/40,0/0,0.00,0.00,0,0,0,0,0,0,0,0

If i run the PR=all (from homeseer)
The comport is opening suc6full after that:

18-10-2012 20:05:59 - OTmonitor error - communication: Waarde kan niet null zijn.Parameternaam: Argument Number is Nothing.


Any idea?

Often i see that there isn't a reply from the comport from within Homeseer.

If i run the OTmonitor everything is working fine.

I've the Remha Avanta with a iSense thermostat. When I send the TR=22 or TR=21 command, the room setpoint changed to 59 degrees....
Other commands like 20, 19, nothing happend. On the iSense the 59 degrees is also visble. I can only change the room setpoint therafter with the iSense.

The OT=outside command is send succesfully and visible on the iSense in the correct degrees.
The TemporaryTemperature device is changed to the correct temperature.

Op zich gaat dat wel..., ik vind 't alleen raar dat de output afwijkt van de input.

Ik heb nog eens wat tests gedaan rechtstreeks in the OT monitor:
Via de Celcia20 tab krijg ik room setpoint waarden van 59/60 graden .e.d, geen optie, ik heb immers ook een iSense thermostaat.
Via de Standard tab zijn de waarden normaler, maar toch werkt 't niet.

Start temp = 18.5 = nachttemperatuur.
1. Ik stel een tijdelijke temp van 19.50 in, een minuut later veranderd de room setpoint naar 19.5
2. 3 minuten later stel ik een tijdelijkse temp van 20.00 in, een minuut later veranderd de room setpoint terug naar 18.5
3. paar minuten later stel ik de tijdelijke room setpoint in naar 21.00 en ook weer hier veranderd/blijft ie op 18.5.

Alle ingevoerde commando's worden bevestigd met OK.
Btw: de OT monitor geeft een outside temp van 3.8 aan, wat ik ook handmatig ingegeven heb, maar mn thermostaat geeft 4.0 aan :shock:

Iemand een idee?

Heb je die experimenten met otmonitor toevallig gelogd? Als je zo'n log aan mij beschikbaar stelt kan ik daaruit misschien herleiden wat er gebeurt en of daar iets aan te verbeteren is.

Natuurlijk had ik geen log, maar heb 't trucje even opnieuw gedaan en je krijgt zometeen de log doorgestuurd

Ik heb hetzelfde probleem met de Isense en de OTG
Als ik temp setpoint of constant set instel op bijvoorbeeld 17.5
Dan zie ik even later ID9 override naar 17.5 gaan.
Wat dan meestal gebeurd is dat even later Override (ID9) weer terug naar 0.0 gaat en de setpoint niet wordt aangepast?
soms werkt het wel en zie ik ook het setpoint naar 17.5 gaan.
Dit probleem komt vaak voor.
Ik kan het logprogje van hvxl niet gebruiken omdat ik de OTG via TTL naar ethernet omzet.
ik gebruik niet de bovengoemde Homseer software, maar heb mijn eigen software.

Zoals ik hier aangaf kun je met otmonitor ook naar een IP adres:poort verbinden.

heb ik geprobeerd maar werkt niet helaas...
geen telnet support denk ik, ik check nog even de EZL specs

Code: Select all
couldn't open socket: connection refused

"socket $host $port"
