OPENHAB and SWIMMING POOL control panel: calibrating PH meter 4502C - VIDEO

Calibration of the PH 4502C probe, using a PH 9.18 solution to define a second calibration point, in addition to the PH 7 point already defined in the previous video.

I update the sketch with the final PH calculation formula and display the value on the LCD display.

For the Arduino sketch I took inspiration from this page: https://www.e-tinkers.com/2019/11/measure-ph-with-a-low-cost-arduino-ph-sensor-board

OPENHAB and SWIMMING POOL control panel: testing PH meter 4502C - VIDEO

In this new video I take up the project of the swimming pool control unit again, starting to test the PH probe purchased on Aliexpress, based on the PH-4502C board.

I used an Arduino UNO, connected to an LCD display for real-time display of the detected values.

OPENHAB in a NUTSHELL: 21. The SEMANTIC MODEL - Refactoring... - VIDEO

In this new video of the OpenHAB in a nutshell series, we always talk about SEMANTIC modeling from a practical point of view, going to do a Refactoring of an already existing non-semantic model.

Let's transform the existing Items into Points and create the respective Equipments to insert into the model, within the Locations.

Once finished, let's see how the dynamic home page has evolved accordingly.

OPENHAB in a NUTSHELL: 19. The SEMANTIC MODEL - Theory - VIDEO

In this new video of the OpenHAB in a nutshell playlist, let's introduce the concept of SEMANTIC MODEL in OPENHAB.

After having seen what groups and tags are, used as basic concepts of semantic modeling, let's talk about the semantic model on a theoretical level, trying to understand what it is and why it is important to use it.

OPENHAB in a NUTSHELL: 17. Groups - The basis of SEMANTIC modeling - VIDEO

In this new video of the OpenHAB in a nutshell series, I talk about the concept of group, the object that is the basis of semantic modeling.

After a small theoretical introduction, let's see together a practical example of configuring a group, starting from its creation up to the management of its value.

OPENHAB in a NUTSHELL: 16. PERSISTENCE check and examples - VIDEO

In this new video of the OpenHAB in a nutshell series, we continue to talk about persistence by checking stored data and their display.

Using API I'm able to read the stored values and create a "chart" page to display them as a time series

OPENHAB 4: Manual installation for LG THINQ binding, used for LG appliances - VIDEO

In this video we install the LG THINQ Binding to integrate LG brand appliances that use the LG THINQ app into OpenHAB.

The installation of the binding is done manually, because it is not a binding officially distributed by OpenHAB and therefore it is not found in the addon store

After installing the binding we create the thing to connect to the LG THINQ cloud and then import the configured appliances.
