Added the option to set timers on setpoint devices in latest beta
The iSense needs to have version V19 (V17 doesn't work and V18 probably won't exists) you can find the version number in the iSense menu.jvandenbroek wrote:Installed the OTGW on my Remeha Calenta with iSense today, and I can read out many values. I know it's an known issue that setpoint doesn't work with this thermostat, but is there a workaround for it? Every time I try to change the Room setpoint, it jumps back to the old value within a minute. Also setting it to 0 or 0.0 and then some other value doesn't work. Quite annoying, since that's the whole point of using such GW
iSense doesn't seem to have a version number printed in information, only language version 18-1-2011??
I think a logic level converter should work, will test this soon.DaaNMaGeDDoN wrote:Question: will it be possible to connect (and USE) an opentherm gateway when connected directly to the GPIO headers on a RPi and make that RPi a slave to an existing Domoticz server?
I plan to build my own OTgw, but drop the RS232 chip from the design, put in the wirebridge instead and instead of using a USB->TTL serial converter hook it up directly to some pins of the RPi GPIO.
Anybody that has experience with that?
Thanks in advance!
In parallel i already have confirmation RPi can be hooked up directly with the OTGW without the usb serial converter, but not in use with Domoticz. I guess it should not be that hard and if i beat you to it i'll post my findings.jvandenbroek wrote:I think a logic level converter should work, will test this soon.DaaNMaGeDDoN wrote:Question: will it be possible to connect (and USE) an opentherm gateway when connected directly to the GPIO headers on a RPi and make that RPi a slave to an existing Domoticz server?

I do not recognize your problem, but I also had the End of file error. That one was gone after I connected the OTGW through USB. I think there is a problem somewhere with the socket connection.Blueone wrote:I have a little problem with the opentherm gateway, I'm not sure if it's a domoticz thing or an opentherm gateway error. The switches Flameon/DHZ on etc aren't active any more, the last seen date is a few weeks ago. The temperature sensors from the OTG are still work so there is a connection. Does someone recognize this problem? I already tried to delete the hardware and adding it again.
I also get this error in the log: 14-11-28 15:20:52 Error: OTGW: Error: End of file, I have this error already from the beginning.
