And the option to set TT (temp. temporary) or TC (temp. constant) on the thermostat

[gizmocuz]

i see only the option to set this for the LED's ....

maybe i missed it.. is it in the status field?
Where?

I also saw it for LED's but i thought when you can turn on/off an LED the OTGW also must be able to report that the LED is turned on/off also if you dont have LED's attached, but i can be wrong. Also the otmonitor tool can display this status. I will try if i can find any msgid or something like that.


I also have another issue. i'm using the stable firmware version at my OTGW, in combination with a Remeha Tzerra M24c boiler and at the thermostat connection of the OTGW i attached my honeywell Opentherm RF module (type: R8810A1018) which is wirelessly connected with my Honeywell Round Wireless (type: T87RF1003) all seems to be working fine (except for some error 01 and 03 messages, any idea?), untill you want to change the temperature. When i change the setpoint of the thermostat in domoticz it is needed a very long time (up to half an hour or so) before it is updated at the thermostat, mostly i send it a couple of times to.

Also, When it is updated from the otmonitor tool provided with the OTGW, (then it is also taken up a long time btw) it is showing the Honeywell HOme Automation system icon on the thermostat. This is not showed when updating the temperature from domoticz, could this be implemented? because i like it!


Edit: Is it also possible to implement in Domoticz that i can choose if domoticz uses the TT or the TC command to change the setpoint? (maybe at the settings of the OTGW at domoticz) As tjoep also requested. Because at the domoticaforum i read that my above problem maybe could be solved when using the TC command in stead of TT what domoticz is using now.

I think these are the ID's you are looking for.

Flame status (Off/On) = OpenTherm MsgID=0 (ID0:LB3: Slave Status: Flame status)
CH Mode (Off/On) = OpenTherm MsgID=0 (ID0:HB0: Master status: CH enable)
DHW Mode (Off/On) = OpenTherm MsgID=0 (ID0:HB1: Master status: DHW enable)

Max Modulation level (%) = OpenTherm MsgID=14
Modulation level (%) = OpenTherm MsgID=17
Water pressure (Bar) = OpenTherm MsgID=18
DHW Flow Rate (l/min) = OpenTherm MsgID=19

Not sure about the error message yet, it could be:
Error Status (No Fault/Fault) = OpenTherm MsgID=0 (ID0:LB6: Slave Status: Diagnostic/service indication)
or:
Error Status (No Service/Service Req) = OpenTherm MsgID=5 (ID5: HB0: Service request)

Quote from the domotiga site about the Master status:

Status Opentherm master
"Idle" = OpenTherm MsgID=0, Lowerbyte: 0000 0000
"Heating up room" = OpenTherm MsgID=0, Lowerbyte: 0000 0010
"Heating up boiler" = OpenTherm MsgID=0, Lowerbyte: 0000 0100
"Cooling down room" = OpenTherm MsgID=0, Lowerbyte: 0001 0000
"Error" = OpenTherm MsgID=0, Lowerbyte: 0000 0001

I have not been able to find any info about the TT and TC setting for the thermostat. Maybe this is Model specific?

Is there a way to turn of the OTGW logging in domoticz? My log is filled these lines:

Fri Mar 7 14:20:04 2014 (Heater) Thermostat (Heater Room Setpoint)
Fri Mar 7 14:20:04 2014 (Heater) Temperature (Heater Room Temp)
Fri Mar 7 14:20:04 2014 (Heater) Temperature (Boiler Water Temperature)
Fri Mar 7 14:20:05 2014 (Heater) Temperature (DHW Temperature)
Fri Mar 7 14:20:05 2014 (Heater) Temperature (Heater Outside)
Fri Mar 7 14:20:05 2014 (Heater) Temperature (Return Water Temperature)
Fri Mar 7 14:20:06 2014 (Heater) Thermostat (DHW Setpoint)

logging is only internally unless you specified that domoticz should log to a file.
If you enabled the log file option, you want to log something (as a developer maybe?) so yes you get log lines
As you get updates to sensors, domoticz makes a log, and yes OTGW updates the sensors....

Thanks for the status id's

Ah ok, i was trying to debug a lua script but the amount of updates from the otgw made it nearly impossible. Ended up disabling otgw while i was debugging.

[gizmocuz]

in the latest beta support for the status bits is added, you will receive them as lights/switches.

About the modulation level, unfortunately i do not receive them, maybe Remeha does not support it.

Are they supported by your CV? Can you see them in the monitor utility?

This looks to be working fine! Thanks for the implementation!
Could you tell me what the difference is between DWH_enabled and DWH_Active and CH_enabled and CH_Active and CH2_enabled and CH2_Active?
The enabled ones im not sure about, the active ones seems to be for example, when you use hot water the DWH_active is on.
But what is the difference between CH and CH2?

Thanks!

[pwhooftman]

CH=Central Heating
DWH=Domestic Hot Water
OTC=Outside Temperature Control

'enabled' means this function is enabled on the heater (one can disable the domestic hot water supply completely if needed), 'active' means it s heating at that moment.

CH2 is for a second zone/circuit which can be controlled by a second thermostat. See http://blog.hekkers.net/wp-content/uplo ... n-v2-2.pdf, look for CH2

I like the new implementations of the OTGW switches.
I rather have them under Utility, but this is okay for now. And I would like to combine the graphs of various states. For example flame-state, CH_active and DHW_active.

But another thing, I can change the thermostat setpoint by hand, but when I use a blocky event to do this, it doesn't work.
I also can't change the domostic hotwater setpoint and the Max_Ch water setpoint (by hand, I didn't try an event for this).

[tjoep]

And if someone is logged in who is a user and not a admin it is impossible to change the thermostat setpoint.

i am thinking about making a thermostat view with all sensors/switches etc..

Can you change those set points with the opentherm monitor application?

Where any changes made to the set point functionality? For some weird reason i cannot change the setpoint from domoticz anymore.
If i update the value nothing happens. There is not even a message in the log saying its being updated.

[Mavy]

Anybody?

[pwhooftman]

Saw this in my Domoticz V1.1637 log just now:

Sun Mar 23 19:41:16 2014 OTGW: Medium power

Any way to show this in a Utility in the Gui?

Could you checked if this has been solved in #1651 ?

[Mavy]

I checked and i can change the setpoint. I was also able to turn protection on and change the setpoint after that. However i can not turn the protection off anymore.
