=================
The adapter supports the following heating system:
- Buderus with the network adapters KM50, KM100, KM200 and KM300
- Junkers with the network adapter MB LANi
- Bosch with the Network Adapter MB LANi
The heating system can be controlled via the Buderus website ([https://www.buderus-connect.de]) or by the 'EasyControl' app from your mobile phone. App and Buderus website also works with Junkers and Bosch heatings systems.
Now I have read in a forum that FHEM and SYMCON offer a driver / adapter for the KM200. These are, however, written in Perl and PHP which I both can not prgramm. I looked at the source code and tried to analyze it and transfered it to node.js. Played around even if I also get an encrypted communication without mistakes.
This has now succeeded in both directions and the adapter is already fully usable.
For this it is necessary to first install the app on a mobile phone and set a private password. The app asks for the device password and the login name off the device.
The adapter still needs the IP (or the network name, for example 'BuderusKM200.fritz.box') and the port address (Port 80 on the device, but if you changed it via a router ...).
Since the adapter must query the data from the system I have defined an update interval, This is set to a minimum of 5 minutes since every update requires a separate query.
My system (2 heating circuits and a hot water circuit) provides more than 150 data points where I can not use most and some are double.
That's why I introduced a black / push list to hide or show certain data. This list consists of strings which are formed into RegExp and the services in the heater are then filtered afterwards.
The syntax is that "/ something *" or "- / something *" everything fades out with "/ something" begins and then any characters (or nothing) has. With "+. * Temp *" you can fade in everything that contains 'temp' and that takes precedence over the faded out!
Mile list looks like `` / gateway * ',' / recordings * ','. * SwitchPrograms. * ',' / HeatSource * ','. * HolidayModes. * "]` And hides about 90 of ~ 150 records my plant off.
Since V 1.1.2 the brackets and commas can be omitted and the blocked / pushed values can only be written with comma!
The system works with services that are structured like a directory tree and this is replicated in the adapter.
- Adapter requires node >= v4.3.
- (Schmupu) Supports Admin3
- (Schmupu) Only device password and own password needed. You do not have to get the access code anymore.
Adapter communication and retries more often to catch more errors.
- Writes are also retried Added blocklist text in config screen
- Adapter handles better communication and retries if he got an error.
- you can set debug-mode by adding 'debug!' in front of host.
- Host port is not required and can be added to hostname with: xxx at end.
- Simpler blocklist handling, which does not ask for device which services are blocked
- Renamed repository to ioBroker.km200
Cleaning of objects / states for current adapters instance which are not part of scanned services anymore.
- Some small bug fixes and added some debug logs. Removed so dependency of 'request' and 'async' modules.
Have only 'request' and 'async' with --save now also registered in the package.json ... Remember: Nuícht --save forget :(!
Strings with allowedValues are now converted to ioBroker states in both directions (read & write)
Setting variables with numbers or strings now works. Thus, e.g. Target temperatures are changed. TODO: Enums and set tables
Adapter now works with blacklist and in read-only mode. TODO: Implement setting values in the heating system TODO: Implement variables with ENUMS (value lists)
First test
