Smarter notifications with Mail Generator & Call Generator

Version 16.1 introduces new Mail Generator and Call Generator function blocks. These blocks allow you to automate notifications using variables such as user information, sensor readings and energy consumption. For example, when an electric car finishes charging, the wallbox can send an email summarizing charging time and energy use. This feature simplifies documentation and provides your clients with personalized updates.

PV Production Forecast for proactive energy planning

A standout addition to Config 16.1 is the PV Production Forecast module. It uses weather service data to predict how much your photovoltaic system will generate. By aligning energy production and consumption, homeowners and businesses can store more energy when high output is expected and conserve reserves when low output is forecast.

Other innovations in energy management

This release delivers several improvements for fine‑tuning energy systems:

  • Flexible Spot Price Optimizer – New functions can be activated without a complete configuration update, allowing quick responses to changing energy tariffs.
  • Faster data from energy meters – The transmission cycle of all Loxone energy meters can now be set to 0.1 seconds, offering rapid feedback for applications such as DC charging stations.
  • Energy meters for current transformers – New meters with folding current transformer sets make it possible to measure currents up to 400 A and conductor diameters up to 35 mm. They are easy to install and integrate via Loxone Tree. These innovations enable precise control over consumption and seamless integration into existing systems.
