Connecting my heatpump „iDM Terra ML Complete HGL“ to OpenHAB 2 using MODBUS via node-red

For some time now I have been using OpenHAB at home for the central control of my house. In OpenHAB, for example, I manage shading, control some lamps, measure and visualize the energy consumption of certain consumers such as refrigerators or washing machines.

The biggest consumer in the house I have not connected yet, my heating. This is a Terra ML Complete HGL heat pump from iDM.

I created a guide how you can acomplish that to get at the end graphs like this using InfluxDB and Grafana:

VORON 2.0 announced and sneak peek

RussianCatFood, the creator of VORON, announced the newest iteration of VORON. The VORON 2.0.

The release date is probably arround Christmas 2017. In the Slack channel of the community he already published some of the features..

Some of the information he shared:

  • The new extruder of VORON 2.0 is the VORON MÖBIUS, you find the BOM, installation guide and the 3D models here:

  • There exists now a configurator to calculate the extrusion and railsizes depending of the print size you want. The configurator allows also to consider an upgrade form VORON 1.0 or VORON 1.5:

Of course i will upgrade to the newest version of VORON, thats the reason why I already created a new project page here on my blog.
