Hydroponik-Sensorbox mit Home Assistant -- 2

@Mahihassi

As an experienced Electrical Engineer with a Master's in Embedded Systems, I specialize in firmware development, PCB design, and complete IoT product engineering. Your project aligns perfectly with my core expertise. Offering a comprehensive solution, I can design and build a compact sensor kit using high-quality pH and EC sensors that come with automatic calibration features. The system will consist of four pH, four EC, and four temperature channels packed in a single box that directly integrates with Home Assistant, ensuring each reading appears as its entity for easy automation and data visualization. In terms of hardware choices for the core system module, I recommend Arduino or ESP-32 to leverage their robustness and your ability to tweak the sketches later on even without extensive programming knowledge. My proficiency in Arduino IDE will ensure clean code structures, comprehensively commented for easy comprehension. For ease of usage and maintenance, the sensors will be connected externally via secure plug-and-play connections integrated into a neatly designed enclosure.

Hello! I am prepared to develop a compact Hydroponic Sensor Box integrating four pH, four EC, and four temperature channels, feeding real-time data directly to Home Assistant. Utilizing high-quality auto-calibrating pH and EC sensors, each of the twelve measurements will appear as distinct entities in Home Assistant for seamless automation and historical graphing. The core system will be based on Arduino or ESP-32 hardware, ensuring easy customization for non-programmers. The aesthetically pleasing non-weatherproof enclosure will feature external sensor connections for easy replacement and stability across all setups. Let's discuss how we can achieve this efficiently.

Hallo, Ich habe Erfahrung in der Entwicklung von multiparametrischen Messsystemen auf Basis von Arduino und ESP32, inklusive pH-, EC- und Temperatur-Messungen mit Home Assistant-Integration. Meine Masterarbeit beschäftigte sich ebenfalls mit Sensorik und automatischer Kalibrierung in Nährlösungen, was mir eine solide Grundlage für Ihr Projekt gibt. Ich kann liefern: Fertiges Gerät mit 4 pH-, 4 EC- und 4 Temperaturkanälen in einem sauberen Gehäuse, alle Sensoren per Steckverbindung anschließbar. Hochwertige, automatisch kalibrierbare Sensoren für pH und EC. Sauber kommentierten Arduino/ESP32-Code inkl. MQTT/YAML-Schema, sodass jeder Messwert als eigenständige Home Assistant-Entität verfügbar ist. Stückliste mit deutschen Amazon-Links für alle Komponenten und ein Kurzhandbuch (PDF) für Inbetriebnahme, Kalibrierung und Anpassungen. Optional: Druckdatei für BambuLab P1S, falls das Gehäuse selbst gedruckt werden soll. Ihr System wird stabil laufen, auch wenn nicht alle Kanäle genutzt werden, und ist später leicht erweiterbar – alles ohne tiefgehende Programmierkenntnisse. Mit einer schnellen Lieferung aus Deutschland ist Ihr Projekt zeitnah einsatzbereit. Beste Grüße, Zakaria L

Hi Thomasr! ich habe Ihr Projekt durchgesehen und spezialisiere mich auf die Entwicklung kompakter Messsysteme. Ich werde ein System entwerfen, das pH-, EC- und Temperaturwerte erfasst und direkt in Home Assistant überträgt und sicherstellt, dass alle Daten als separate Entitäten angezeigt werden. Lassen Sie uns schnell besprechen, wie wir das umsetzen können! Best Regards, Amjad Iqbal

@zeljkoi6

Hallo, Ich freue mich über Ihr spannendes Projekt zur Hydroponik-Sensorbox! Mit über zwei Jahren Erfahrung im Bereich der Mikrocontroller und Automatisierung habe ich erfolgreich ähnliche Systeme mit Home Assistant integriert, darunter Projekte mit Arduino und ESP-32. Ich werde sicherstellen, dass alle Messwerte als separate Entitäten in Home Assistant erscheinen und die Qualitätsstandards für pH- und EC-Sonden erfüllt sind. Ich plane, Ihnen schnellstmöglich eine präzise Stückliste mit deutschen Bezugsquellen sowie ein funktionales Gerät in einem professionellen Gehäuse zu liefern, sodass Ihr System ohne weiteres Programmieren stabil läuft. Best regards,

Hallo, ich kann dir eine kompakte 4× pH + 4× EC + 4× Temperatur Sensorbox bauen, die alle 12 Werte als eigene Entities in Home Assistant bereitstellt (MQTT oder ESPHome), inkl. sauberem Gehäuse und leicht verständlichem Arduino/ESP32-Code. Der Fokus liegt auf Stabilität: ungenutzte Kanäle stören nicht, und Kalibrierung/Drift wird sauber gehandhabt. Um die schnelle Beschaffung in DE zu erfüllen, liefere ich: • Stückliste ausschließlich mit Amazon.de-Links (DE) + klare Alternativen, falls ein Artikel ausverkauft ist • Vollständigen, kommentierten Quellcode + YAML/MQTT-Schema für Home Assistant • Gehäuse als STL/STEP (druckfertig für BambuLab P1S, ohne Support-Orgien) inkl. Beschriftung der Buchsen • Kurzes PDF-Handbuch (Inbetriebnahme, Kalibrierung pH/EC, Anpassungen) Technikvorschlag: ESP32 + getrennte, rauscharme Analog-Frontends pro Kanal (BNC/Steckverbinder), saubere Referenz/Filterung und temperaturkompensierte EC-Auswertung. Kurze Fragen: Welche Sonden/Stecker willst du (BNC?) und bevorzugst du ESPHome (am einfachsten für HA) oder MQTT mit Arduino-Sketch?

Hi, I propose using an ESP32 for the core, as it supports easy integration with Home Assistant via MQTT. For the sensors, I will source high-quality pH and EC probes with automatic calibration. The design will ensure that each sensor value appears as a separate entity in Home Assistant, allowing easy automation and history tracking. I'll provide a complete list of German suppliers and ensure the hardware is ready for quick delivery. The system will be fully assembled and tested, with clear code and setup instructions.

@cameronn0

Hi, For your system, I recommend using an ESP32 for seamless integration with Home Assistant. The pH, EC, and temperature sensors will be high-quality, with automatic calibration where applicable. I will ensure that the system is modular, so unused sensor inputs do not affect others. You’ll receive a full parts list with Amazon links for fast delivery in Germany, plus a clear, commented Arduino sketch for easy future adjustments. I'll also create an STL file for 3D printing the housing on your BambuLab P1S.

@evanderl

Hi, For this project, I’ll use an ESP32 with MQTT for real-time integration into Home Assistant. The pH, EC, and temperature sensors will be sourced from reliable suppliers with automatic calibration capabilities. I'll deliver a fully tested, compact unit with a clean, 3D printable housing design compatible with BambuLab P1S. The system will automatically generate 12 separate entities in Home Assistant, and I will ensure you get clear, easy-to-follow code and German Amazon links for all components.

@johna220

Hi, I’ll design a compact, modular sensor system based on an ESP32. The pH, EC, and temperature sensors will feature automatic calibration and be easy to replace. The system will pass all data to Home Assistant as individual entities via MQTT. I’ll provide a parts list with German suppliers’ Amazon links for fast shipping and delivery. You'll get a fully assembled system with clear documentation and a simple, well-commented code for future tweaks.

@dominicp75

Hi, I’ll use an ESP32 to integrate pH, EC, and temperature sensors into Home Assistant with MQTT. The system will handle 12 sensor inputs with no interference between active or inactive inputs. I will provide Amazon links for German suppliers to ensure fast delivery and will include a 3D-printable housing design for your BambuLab P1S. The project will come with clear, commented code, a complete BOM, and easy setup instructions. Let’s get started on building a stable and expandable system for you!
