OpenHAB - SmartHome

In this second part of the integration process of the light and rain sensors that we saw in the previous videos, connected to the SONOFF via ADS1115 and serial port, we go deeper into the creation of OpenHAB objects (things, channel, items) via MQTT integration.

As we saw in the previous videos, the data comes from a SONOFF 4ch with TASMOTA firmware via MQTT protocol, connected to the sensors via serial port and ADS1115 analog / digital converter, using the I2C protocol; this configuration allows you to acquire analog values ​​on digital pins, very useful for devices that do not have analog inputs or that do not have enough of them.

In this video I show the MQTT configuration with TASMOTA for my SONOFF 4CH, so that I can send to OPENHAB the values ​​of the light and rain sensors that we saw in the previous videos, connected to the SONOFF via ADS1115 and serial port.

After having tested the light sensor and the rain sensor, connected to a sonoff 4CH with TASMOTA firmware (see previous post), let's see the configuration together.

In this video I will guide you step by step through configuring Tasmota on a Sonoff 4CH to read analog data from a dusk sensor and a rain sensor via an ADS1115.

I tested the light sensor and the rain sensor, connected to a sonoff 4CH with TASMOTA firmware.

The SONOFF, using serial connection, is able to obtain the data of the two analog sensors, thanks to the use of an external ADC that allows up to 4 analog connections.

Let's see what happened

New video of the OpenHAB in a Nutshell series.

Let's introduce the SITEMAP, the historical user interface of OpenHAB, describing its features and peculiarities that make it still useful for many use cases.

SITEMAP are used mainly in mobile APP, both iOS and Android, because they are very lightweight and clean.

Let's resume the OpenHAB in a Nutshell series, addressing the topic of graphical interfaces from the end user's point of view.

In this video I make a brief introduction on all the types of pages present in OpenHAB, with particular attention to the default home page, closely linked to the semantic modeling of the system

Very short video to verify the correct execution of INFLUXDB 2 TASKS, which allow the historicization of some data acquired by OpenHAB.

As the last step of the InfluxDB v.2 64 bit update from the old 1.8 version, I migrate the continuous queries to the new INFLUXDB TASKS.

This step is used to efficiently manage the historical data, being able to define automatic aggregation and archiving rules.

After updating the InfluxDB 1.8 docker container to version 2, we verify the presence of the migrated data, using Grafana.

Then we do the final configuration of the docker container and modify OpenHAB so that it can write to INFLUXDB v. 2

Finally, let's upgrade InfluxDB from v 1.8 to v 2.0 using docker containers and the official procedure.

After duplicating the Influxdb 1.8 container, let's create the container with Influxdb 2 image, following the upgrade procedure for data and configuration.

Let's run some read and write tests on InfluxDB v. 2 using OpenHAB and Grafana.

We are almost ready for the final migration

Let's install InfluxDB v. 2 on Raspberry PI 4 with 64 bit Openhabian OS, using a DOCKER container, together with my current InfluxDB v. 1.8 instance

Short video update on my UI2FILES software, which is used to migrate the configuration made via MAIN UI to text files.

I have inserted some changes to handle the lack of management of aggregation functions on groups and the management of profiles in the configuration of links between items and channels

Short video to show a problem I had on my fresh installation of OpenHAB 4.2.

The current time used by OpenHAB for logs and rules invocations was wrong by one hour. The problem was the time zone not set correctly.

It seems that setting the correct time zone on the operating system and in the OpenHAB settings is not enough, but an additional step is needed to definitively solve the problem.

Idea had following the content of a POST of the official OPENHAB forum, which you can find at this link: https://community.openhab.org/t/oh3-does-not-respect-the-local-timezone/121850
