  • Tasmota Plug – Control with Node-Red and MQTT

    18. Mai 2025By

    Here you will find some Projects to control Tasmota Plugs with the help of Node-Red and MQTT. Requirements are an RaspberryPi ore a Server on which Mosquitto, Node-Red with Dashboard is installed. The Tasmota Plugs should be configured to work in your MQTT Environment, so you have to use Topics, that will fit your naming themes.

    Tasmota is an open source firmware for Espressif ESP8266, ESP32, ESP32-S or ESP32-C3 chipset based devices created and maintained by Theo Arends.

    Tasmota Logo

    You can flash Tasmota Plugs with the Tasmota Firmware: https://tasmota.github.io/docs/

  • Keep your basement dry – WITHOUT electricity costs

    18. Mai 2025By

    If you have the problem that a room in your basement is damp, this project might help you.

    Keep your basement dry – WITHOUT electricity costs with an “Digital 2-in-1 Dehumidifier” (Sichler electric dehumidifier, dehumidifier & air purifier model: LFT-200 or any other dehumidifier of your choice thas can be switched on / off via the powercord)
    => Control the dehumidifier trough a Tasmota socket and Node-Red, Mosquitto via MQTT on a Raspberry Pi. Switching times are based on adjustable thresholds for battery charge.

    Requirements:

    • Raspberrypi with Node-Red with Dashboard and Mosquitto MQTT Broker installed
    • PV system with batteries: home power station E3/DC
    • RSCP2MQTT installed on the Raspi [(https://github.com/pvtom/rscp2mqtt)] to get Values from the Station
    • Tasmota socket with MQTT switched on and configured for the Mosquitto Broker
    • “Digital 2-in-1 Dehumidifier” or any other Dehumidifier which can be controlled with the Tasmota plug

    The Dehumidifier i´m using:

    Shop where you can buy the Dehumidifier

    Installation

    Verify that the above Requirements are met.
    Import the flow into Node-RED.
    Make corrections in the Nodes for your System:
    Activate and test the flow.

    Usage

    The flow runs automatically in the background and monitors the incoming values form the PV System.
    If the adjusted Value are reached, the Dehumidifier will start working and drying the Air. If the values are not met it will stop.

  • Window- Doorsensor Monitoring with ZigBee2MQTT, Node-RED on a Raspi

    5. April 2025By

    Overview

    This Node-RED flow is designed to monitor a ZigBee-based WC (restroom) window sensor. It detects the window status (open/closed) and monitors the sensor’s battery level. Relevant state changes trigger Pushover notifications. Now a new Version is online V1.1 with little improvements in the Dashboard when the flow starts.

    Features

    • Window Status Detection: Identifies whether the window is open or closed.
    • Battery Status Monitoring: Keeps track of the sensor’s battery level.
    • Notification System: Sends Pushover notifications when the sensor contact is open for a adjustable time, when the sensor will be closed or the battery level is low.

    Requirements

    • Node-RED installed
    • ZigBee sensor compatible with Node-RED (i have used the Aquara MCCGQ11LM)
    • Pushover credentials to use the notification feature

    Installation

    1. Install Node-RED your desired system.
    2. Required Nodes: Dashboard, Pushover, ZigBee2MQTT, node-red-contrib-ui-led
    3. Import the flow into Node-RED.
    4. Create an Pushover Account if you don´t have
    5. Configure the required Pushover Api Node with your credentials.
    6. Activate and test the flow.

    Usage

    • The flow runs automatically in the background and monitors the sensor.
    • A push notification is sent if the window is opened for an adjustable time, when it ist closed or the battery is low.

  • Node-Red Control Proxon T300, E3DC, Shelly

    9. November 2024By

    Control Proxon T300 hot water storage tank PV priority switching input with ShellyPlus1 via MQTT and Node-Red

    Overview of the project

    Control of the PV priority switching input of the T300 hot water storage tank of a Proxon ventilation heating system using a ShellyPlus1 via Node-Red and MQTT. The ShellyPlus1 is controlled via Node-Red and MQTT in such a way that the priority switching is activated when an adjustable battery charge and the feed-in reaches an adjustable wattage and deactivated again when the values are undershot. A pushover message is sent on activation and deactivation so that the switching processes can be monitored even when nobody is at home.

    On the circuit board of the T300, on which the display is also soldered, there is the terminal block X13. The circuit board is on the back of the display. To access the terminal block, you must first remove the long strip on the front below the display. It is only pressed into the side of the insulation of the device with pointed claws. There are three screws behind it that need to be loosened. You can then remove the entire upper part of the device insulation upwards. The display is inserted into two grooves and must be held firmly when sliding it out to prevent damage. The priority circuit of the PV system is located on terminal block X13. The switching input of the ShellyPlus1 is connected to X13-1 and X13-2. Please remember that this is a potential-free contact. The suitable relay in this case is the ShellyPlus1. The control line can be led out of the T300 through an existing opening at the rear (this can be seen when you have removed the cover and the display) using a two-pole cable (I used a telephone cable). This cable have to bo connected with to the I/O connections of the Shelly 1 (note: only the ShellyPlus1 is potential-free!) and then evaluate all available parameters via the home automation system (battery charge status, current yield and thus switch the PV priority on or off.

    The terminal block X13 has 3.3 V at the connection itself. Following Parameters in the installer menu (code 1000) have to be adapted:

    In the Installer menu:

    Set F22 PV mode to SG (Smart Grid). This activates the digital input
Set F23 PV Eheiz to 5V
Set F24 PV WP to 5V
Set F25 WP Time to 5 min (or what you want, this is the time to wait bevor X13 switches to on)

    In the Settings menu:

    D05 PV Priority ON

    After I contacted Zimmermann, they sent me a CVS file with all the Modbus information, the wiring can be seen on the circuit diagrams that were given to me at the time of acceptance. Please leave me an email via PM and I can send you the CSV file.

    Installation, requirements

    1. Raspberry Pi is required as host for the other requirement
    2. Install an MQTT Broker (i used Mosquitto)
    3. Install Node-Red with Dashboard
    4. Install RSCP to MQTT Dashboard v1.0
    5. Install node-red-node-pushover – required to send Pushover Messages
      • a pushover account should be created, if you want to use it when the trial period ends, you have to pay $5. See Infos here: https://pushover.net/pricing
    6. Configure ShellyPlus1 and integrate it into the network, so you can use it via MQTT
    7. Connect the switching input of the Shelly to X13 1 + 2

  • Node-Red – Flows, Nodes, Infos

    18. Oktober 2024By

    Hier findet ihr Infos zum Thema Node-Red, Mosqitto, MQTT und was so zu dem Thema gehört.

    Ich werde auch anonymisierte Flows und Nodes hier zur Verfügung stellen, die bei mir auf meinen Systemen laufen. Wäre schön wenn Feedback kommt mit Verbesserungsvorschlägen. Wenn jemand die Sachen gebrauchen kann, dann einfach übernehmen.

    Gruß
