No idea what it does yet but that's easy to find out.

Another question: my dev toon is not connected to the boiler. Does anyone know if there is an opentherm boiler simulator (via a raspberry for example?) out there which I can connect to the 'keteladapter' ?

It' s probably a pre-populated list of values based on boiler manufacturer and Boiler (Beta) user input.
I can also see in the strace from happ_thermstat that Toon is actively checking for exisiting ID's and throws a "Not supported" message otherwise.

Aren't all available variables not listed in qmf_project.xml?
Values are also logged and stored in rra databases (see config_hcb_rrd.xml)

Yes.

It consist of an OTGW with the interface firmware flashed onto it, a USB-to-serial adapter and a piece of software (GPL, although I haven't added the notices yet

), running on a linux box (typically my laptop computer, but a raspi will do nicely).
Just yell if you want it (the software, you will have to buy the hardware yourself).

Yep, very interested, just need to buy the OTGW interface hardware. Any tips which one to buy?

AFAIK the pre-soldered ones are out of stock, although Nodo apparently still manufacture them on demand (SMD type).
Serial ports are rare these days, so I'd go for the USB one, unless you have a serial converter lying around (RS232 serial, that is, not the TTL type).
Just check the OTGW site for details (or ask Schelte Bron, a.k.a. hvxl, at this forum).

This is just the app where you can register your boiler brand/model/type and give consent to Eneco to use these data.
It also asks for the installation date, last maintenance date and maintenance interval.
Nothing else.

By the way, works fine on a rooted Toon if you open the VPN to Eneco and have added the app to globals.qml

You reminded me of a post from januari 2017 where we already saw the OT data being graphed.
See this post domoticaforum.eu/viewtopic.php?f=87& ... rrd#p81562
I just don't get why they are scanning all the OT ID's and do nothing with all the others (read: make them somehow available to us) What's the point of filling in wich Boiler brand you have if they don't use the extended ID's. Let's blame sales, marketing and big data for now.

By the way, these are the values that are being graphed. I left out the obvious ones for comparison.
I used MarcelR's hcb_rrd.php script for this (Still working Marcel, must be one of the early day scripts)

Had a quick look, it isn't as easy from QML because interaction with bxt is via the built-in module BxtClient which has a defined set of functionality.
I cannot call bxt directly from qml.
If we could write all variables in a txt file via a cron jobs with bxt calls then I can easily display it in a tile or screen.

How about something in the line of this:
(boiler/BoilerApp.qml)

Code: Select all

var msg = bxtFactory.newBxtMessage(BxtMessage.ACTION_INVOKE, p.thermstatUuid, "specific1", "GetBoilerBrands");
// Timeout is one second more than the timeout in happ_scsync
bxtClient.doAsyncBxtRequest(msg, parseBoilerBrands, 16);
return requestId;

You can construct the same messages from bxt debug:

This will probably do:

bxt debug:

Code: Select all

qml code:

Code: Select all

var msg = bxtFactory.newBxtMessage(BxtMessage.ACTION_INVOKE, p.thermstatUuid, "specific1", "BoilerChPressure");
// Timeout is one second more than the timeout in happ_scsync
bxtClient.doAsyncBxtRequest(msg, BoilerChPressure, 16);
return BoilerChPressure;

will give it a go tomorrow evening....

Ofcourse if all fails whe can whip up something quick&dirty in php, query bxt (remote) and scan the output for the values but what's the fun of that

Hi All,
I have a small problem booting my Toon, it stuck on the boot process and give a kernel panic error , is there anybody who can help me out:

Looks like a rotten UBIFS partition. Not good.
I have had something very similar, some time ago. It was quite an operation to get everything back in working order:
