Got the esp working with ESP-link. Showing the everything from the thermostat and boiler. However, the binding 0.8.0 does not allow me to configure anything in PaperUI. It just shows the binding, but no channels, no configuration etc. Do I miss something?
@PGustias thanks for the detailed screenshot, this really helps me in mapping the data sent through opentherm to the binding.
@JdeJong you should be able to configure the IP address to connect to the OTGW device. After that, a complete list of channels should be available in openHAB which also shows up in PaperUI. The sources are currently not available on Github, because the structure of the openHAB sources has changed quite a bit and I haven’t had the time to adjust the sources of the binding to match the new structure. Is there anything in particular you are interested in regarding the sources of the binding?
The thing is, that the bindings in the upstream repo from openhab were moved from /addons/binding to /bundles, and with it of course also the build scripts etc. So I ran into a lot of issues when creating a pull request.
Unfortunately documentation (both openhab and eclipse smarthome) is now out of date or contain broken links to examples of how to get things working… so if you can help me out by explaining how the new forlder structure works or how to migrate the binding from the old to the new structure… that would be very helpful
Your question is more related to the OpenTherm gateway device itself than the binding. The OTGW website indeed states that for temporary override (TT) and constant override (TC) a value of 0 cancels the override. But I have never tested this myself.
Please let me know if it works, if not I have to look into it.
Tested today. The override for DHW works and can be removed by setting it to 0.
What doesn’t work is the override for the room temperature. But it’s not related to removing the override, it just won’t take the override at all.
It always shows the temperature of the thermostat.
I also checked the log and there only the setpoints of the thermostat is returned.
One thing that is important to know: I have two different heating circuits, one for floor heating and one for radiators in the 1st floor. Within the thermostat I can set two different setpoints. Only one is shown in the plugin.
Do I have to change anything to be able to set both setpoints through the gateway? Or at least one of the setpoints?
I am not sure how it would work with two circuits… but if the boiler has two room setpoints, that might explain why the constant or temporary room setpoint override doesn’t work. With this binding though, I am limited to the features of the OTGW device. And as far as I know, it doesn’t support overriding two separate room setpoints. At least, not with the standard firmware.
If you check the OTGW site with the link I provided earlier, you will see all the commands the OTGW device supports. Some commands are mapped to channels, like temporary and constant override, but any command not mapped to a channel can always be set through the generic “Send command” channel of the binding.
Please check if you can get the setup working with just the OTGW device and OTmonitor or telnet or something… to find out whether the issue is with the binding or the hardware.
I have an Elco Thision 9 gas boiler, with a Siemens LMU54 controller.
When I manually cut off the gas, I get the fault code 133 : No flame during safety time.
But unfortunately I get this fault also from time to time by an abnormal startup of the boiler …
This code is indicated on the display of the boiler and also correctly decoded with version 0.9.0 of your binding.
I found for my boiler a list in this manual on page 25.
But I think this list is vendor and boiler specific !
I found for your boiler on page 50 of this manual :
Error code E4 : More than 5 start attempts without any flame formation.
This must be corresponding with my code 133 …
Do you find back this OEM fault code E4 in your binding ?
Or do you see this code in the original OpenTherm Monitor application ?
Kind regards and thanks for all your efforts and keep up the good work,
Remeha has some mapping from the faultcode that is reported on opentherm (133) and the faultcode in the manual and also the display on the boiler itself (E4).
So… I did find this list of Exx codes… but that’s not what I get back on opentherm.
Well, it’s not that big of a deal… my boiler hardly ever goes into fault mode, and even if it does, the general fault indication is still activated on opentherm, so I just need to check the display and find the corresponding Exx code to find out whats wrong.
