Most everything needed for your heater-system to be shown at your 'hometop' -> pimp your heater.

This project is limited to recording/controlling and presentation of heating and solar informations. Currently only heater-systems from german manufacturer: Junkers and system-bus: Heatronic/EMS2 (c) are supported.

This repo can not fulfill all wishes you could have to your 'hometop'. Each has his ideas such as the 'home' can be 'Top'. The presentation of informations from the own 'home' with it's heater-system is what this repo will do. Other projects are working too on this item, example: FHEM

This repo was started creating some different boards for the RaspberryPi(c).
The table shows the currently available boards:

The software is written in python and designed for detection, decoding and controlling of HT - busdata with following features:

For project - details see the documentation (folder: ~/HT3/docu ) and the following links:

• RaspberryPi HT-board forum: HT-Boards
• Software-forum: HT-Software

The current software can be found in subfolders: ~/HT3/sw/...
Any hardware informations are in subfolders: ~/HT3/hw/...

The software is still under development, but any official release should be runable 'out of the box' under Linux.
For Windows some improvements are required and will be done in the future.

If you have got any problems with hard- or software, let me know.
Also your support with binary - logfiles is good to have for further development.

Thank's to all supporting me, in the past and future.
We all want to have the right thing in the right time.

  • Default configured to: On.
• autoerase_olddata added in configuration-file: HT3_db_cfg.xml for deleting old dataentries in sqlite-db.
  • Default configured to: 30 days.
• db-table: rrdtool_info unused and deleted in sqlite-db.
  • rrdtool-db is updated instead every 60 seconds with all current data.

  • you must have a lot of free space on your drive (> 1 GB in folder: /tmp) doing this upgrade.
    

  • the upgrade takes a lot of time do be finished.
    

  • if this space isn't available, remove the old database and create a new rrdtool-database.
    

• importend notice the current sqlite-database must be deleted or renamed and has to be recreated for this release:0.2 using tool: ./create_databases.py.
