The following integration is using the Modbus RTU communication protocol. The weather station used in this example is ELSNER ELEKTRONIK P03/3 Modbus. This integration allows us to receive the following information: - temperature value - brightness value from East, South and West - wind strength value - detection of precipitation. To complete this example, we need: - Gate Modbus - Weather station P03/3 Modbus.   **Configuration of Modbus periphery objects** 1. According to the weather station's [documentation](https://knowledgebase.grenton.com/hubfs/TU-0009-EN-120509.pdf?hsLang=en), we make settings that will allow Modbus communication. 2. We add Modbus periphery objects: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Apr-03-2025-11-48-34-7665-AM.png?width=336&height=274&name=image-png-Apr-03-2025-11-48-34-7665-AM.png) 3. We complete the values of the embedded features: - Rain: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Mar-13-2025-10-03-29-1854-AM.png?width=688&height=792&name=image-png-Mar-13-2025-10-03-29-1854-AM.png) - Temperature: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Mar-13-2025-09-18-11-1896-AM.png?width=688&height=791&name=image-png-Mar-13-2025-09-18-11-1896-AM.png) - Wind speed: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Mar-13-2025-10-04-12-7376-AM.png?width=688&height=792&name=image-png-Mar-13-2025-10-04-12-7376-AM.png) - Brightness - south: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Mar-13-2025-10-11-41-6849-AM.png?width=688&height=792&name=image-png-Mar-13-2025-10-11-41-6849-AM.png) - Brightness - east: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Mar-13-2025-10-12-34-4995-AM.png?width=688&height=792&name=image-png-Mar-13-2025-10-12-34-4995-AM.png) - Brightness - west: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Mar-13-2025-10-39-05-0951-AM.png?width=688&height=792&name=image-png-Mar-13-2025-10-39-05-0951-AM.png) **Reading register values in the myGrenton application**  1. We create an interface with *Value* widgets: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Mar-18-2025-11-43-20-7045-AM.png?width=402&height=796&name=image-png-Mar-18-2025-11-43-20-7045-AM.png) 2. The *Value* field we complete with the *Value* feature of the appropriate register: ![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Mar-18-2025-11-44-28-1485-AM.png?width=688&height=576&name=image-png-Mar-18-2025-11-44-28-1485-AM.png) We do the same with each parameter we want to include in the interface. ![](https://knowledgebase.grenton.com/hubfs/Knowledge%20Base%20Import/support.grenton.plensupportsolutionsarticles35000165001-integration-with-the-elsner-p03-3-modbus-weather-stationhit-2.gif) - [Installation guidelines](https://knowledgebase.grenton.com/en/installation-guidelines?hsLang=en#main-content) - [How to Prepare Electrical Installation](https://knowledgebase.grenton.com/en/installation-guidelines?hsLang=en#how-to-prepare-electrical-installation) - [Reference devices](https://knowledgebase.grenton.com/en/reference-devices?hsLang=en#main-content) - [Integrated Device](https://knowledgebase.grenton.com/en/reference-devices?hsLang=en#integrated-device) - [Most Common Mistakes](https://knowledgebase.grenton.com/en/most-common-mistakes?hsLang=en) - [Electrical Installation](https://knowledgebase.grenton.com/en/electrical-installation?hsLang=en) - [Manuals](https://knowledgebase.grenton.com/en/manuals?hsLang=en#main-content) - [Gate Modbus](https://knowledgebase.grenton.com/en/manuals?hsLang=en#gate-modbus) - [Training](https://knowledgebase.grenton.com/en/manuals?hsLang=en#training) - [SW Applications](https://knowledgebase.grenton.com/en/manuals?hsLang=en#sw-applications) - [Gate HTTP](https://knowledgebase.grenton.com/en/manuals?hsLang=en#gate-http) - [Smart Panel](https://knowledgebase.grenton.com/en/manuals?hsLang=en#smart-panel) - [Configuration](https://knowledgebase.grenton.com/en/manuals?hsLang=en#configuration) - [myGrenton interfaces](https://knowledgebase.grenton.com/en/manuals?hsLang=en#mygrenton-interfaces) - [Virtual Objects](https://knowledgebase.grenton.com/en/manuals?hsLang=en#virtual-objects) - [Gate Alarm](https://knowledgebase.grenton.com/en/manuals?hsLang=en#gate-alarm) - [Intercom](https://knowledgebase.grenton.com/en/intercom?hsLang=en) - [FAQ](https://knowledgebase.grenton.com/en/faq?hsLang=en#main-content) - [FAQ](https://knowledgebase.grenton.com/en/faq?hsLang=en#faq) - [About Grenton](https://knowledgebase.grenton.com/en/faq?hsLang=en#about-grenton) - [Price list and documents](https://knowledgebase.grenton.com/en/price-list-and-documents?hsLang=en) [![Grenton logo](https://knowledgebase.grenton.com/hs-fs/hubfs/Logo_Grenton_variants_BIG_2020_plus_RGB_v0.2-02.png?width=400&height=100&name=Logo_Grenton_variants_BIG_2020_plus_RGB_v0.2-02.png "Grenton logo")](http://grenton.com) Copyright © 2026, Grenton Sp.z o.o.
