Would it be possible to add a value to the PS=1 report which indicates if a Room Setpoint Overrule is active ? I am developing a thermostat which uses values from the PS=1 report. This thermostat needs to 'know' if the room setpoint is overruled or not for showing the appropriate controls.

You can get the gateway's best guess of whether the setpoint is overruled using the PR=O command.

Schelte,
is it possible to use 'CS' & 'CH' with thermostat connected or those commands are suited only for thermostat less configuration?
Are there corresponding PR commands for 'CS' & 'CH'?

The 'CS' and 'CH' commands are supposed to work with a thermostat connected. Do you have a different experience? There are no PR commands for these commands, mainly because I'm running out of code space on the PIC.

My thermostat doesn't support room setpoint override
Heating system is installed in my country house, which is not constantly in use during winter time. The main idea is keeping house on reduced temp. and reheat before arriving.
I have MAX! system installed and I'm thinking to manipulate water temperature depending on valve positions.
Could you please answer more questions?
- How to "clear" CS & CH parameters? I've got SE & BV responses on non-numeric values
Is it possible to use CH command without CS?
Also I want to ask you to add more DBus signals in otmonitor, such as:
- DHW control (enable, setpoint, temperature, on/off)
Central heating enable, modulation level, water temperature, return water temp
GW reset

The CH setting only takes effect when CS is not 0. CH defaults to 1. So, to clear the settings use CS=0. To just restore CH to its default, use CH=1.
I added your request for more DBus signals on the feature request list for otmonitor.

But this should only happen if you used really small resistors for your LEDs, around 100 Ohm or less. If you used the same resistors for the red and green LEDs and the green LEDs work fine, you are probably close to the tipping point. One possible technique you can try that doesn't require a soldering iron is to increase the resistor value using a file:

I don't know how far you can take that, but if you expect to throw away the resistors anyway when you get your hands on a soldering iron, you can give it a shot.
I've got leds with built-in resistors, according to datasheet current is up to 30mA. I'll change them or add resistors in 2 weeks when will come back to my country house.

Added resistors, no more problems. Thank you for your time.

Schelte,
I checked SR command and I have got an idea: new command which will send alternative command instead of requested.
For example I have many "10 - Read - Number of TSPs" requests which always return the same answer.

You mean like UI=10 ?

If UI means unknown-id, no
I mean SA=10:0,43
Always return value to thermostat and ask alternative from a boiler.
Corresponded clear command should be also added

UI does mean unknown ID. What kind of magic do you think that does? It's just an indication to the gateway that it doesn't have to bother sending the message to the boiler. Combine that with the SR command to specify what you want the gateway to send back to the thermostat and I think you have what you were asking for. If not, then it's not clear to me what you want.

Yes, it is exacrly what I want, but the real life is ...:
Code: Select all
15:41:08.885488 Command (via websocket from 192.168.7.24:60724): SR=10:42,0
15:41:08.911464 SR: 10:42/0
..........
15:41:20.568754 Command (via websocket from 192.168.7.24:60724): UI=10
15:41:20.584186 UI: 10
..........
15:41:53.632278 T000A0000 Read-Data Number of TSPs: 0
15:41:53.648008 R80190000 Read-Data Boiler water temperature: 0.00
15:41:53.814387 BC0195200 Read-Ack Boiler water temperature: 82.00
15:41:53.825483 AF00A0000 Unk-DataId Number of TSPs: 0
Thank you very much for your support.

I guess you are experiencing interference from the feature to read TSPs that was introduced in firmware 4.0b4. I suspect it works with 4.0b3. Any chance you could test that?

Checked with 4.0b3, working as expected, so something wrong with b4
PS. I tried PM=10, it's working ... may be you could add special TSP screen to otmonitor (both gui & web)?

Thanks for reporting that the PM=10 functionality works. I couldn't check that myself because my boiler doesn't support any of the TSP/FHB messages.
I have fixed the SR command when used on TSP/FHB messages in
firmware version 4.0.
