FAQ
TL;DR: Looking for a wired home‑automation PLC? Sterbox shows 6 years in service—"Zero problems, easy programming"—with browser-based setup. Prioritize free software and simple expansion when starting out. [Elektroda, kSmuk, post #17798024]
Why it matters: This FAQ helps homeowners and DIYers choose a wired PLC and smartphone-control path that scales without overspending.
Quick Facts
- Siemens S7‑1200 and WAGO were explicitly recommended as wired starting points. [Elektroda, Interval, post #17777711]
- Sterbox can be configured in a web browser and offers many functions. [Elektroda, kSmuk, post #17798024]
- Use external relays or contactors when switching mains loads with Sterbox. [Elektroda, kSmuk, post #17798024]
- iOS users have three Sterbox control apps; check Android options. [Elektroda, kSmuk, post #17811066]
- Delta PLCs and Weintek HMIs provide free, intuitive design software. [Elektroda, PRL, post #17810355]
What PLCs are recommended for wired home automation with expansion?
Siemens S7‑1200 and WAGO were explicitly recommended in this thread for wired builds. Use them as a safe starting point. [Elektroda, Interval, post #17777711]
Is Sterbox reliable and easy to program for a house?
One user ran Sterbox with two expansion modules for six years. They reported, "Zero problems, easy programming," via a web browser. The controller provides many functions and suits lighting control well. Use external relays or contactors for power circuits. [Elektroda, kSmuk, post #17798024]
Does Sterbox support smartphone control over Wi‑Fi?
Yes. As reported, "Yes, it does... for iOS there are three apps." Android availability was not confirmed in the thread. Plan to verify app support before you buy hardware. [Elektroda, kSmuk, post #17811066]
How do I control a garage door if Sterbox’s site shows only roller shutters?
Treat Sterbox as a general controller. Connect sensors, pushbuttons, and relays to its I/O, then implement door logic. You wire relays to control the motor and handle interlocks. The same pattern works for lighting and other loads. [Elektroda, kSmuk, post #17810255]
I’m a beginner and want free software—what should I pick?
Choose a PLC that offers free programming software and low-cost accessories. Favor platforms that feel easy for you to program. Simpler tooling reduces setup time and errors. This selection strategy helps you scale the system later. [Elektroda, xury, post #17777820]
Do Delta PLCs and Weintek HMIs have free, intuitive software?
Yes. A contributor highlighted that both Delta and Weintek provide free, intuitive design environments. Download the tools first to assess fit. Free tooling lowers initial costs and encourages experimentation. It also reduces licensing friction for small projects. [Elektroda, PRL, post #17810355]
Is a Weintek HMI a good choice for a home project?
Yes. Weintek panels received a strong endorsement and run well in industrial settings. That confidence usually translates to stable home installations. If you need a touch UI, Weintek is a safe pick. "Most positively" was the verdict shared. [Elektroda, Interval, post #17810330]
Should I use a non‑PLC approach to save money?
Consider non‑PLC options if budget is tight. One comment implied PLCs cost more, and suggested Sterbox if you insist on a PLC. Non‑PLC builds demand more DIY work and safeguards. PLCs trade higher cost for integrated robustness. [Elektroda, omnixcrs, post #17797931]
Do I need external relays to switch lights or motors with Sterbox?
Yes. Drive an external relay or contactor from the Sterbox output. This protects the controller and handles bigger loads. The reported installation stressed using external switching hardware. It’s a best practice for reliability and safety. [Elektroda, kSmuk, post #17798024]
How do I wire a load with Sterbox using an external relay?
Do this:
- Wire your wall switch or sensor to Sterbox inputs.
- Use a Sterbox output to energize an external relay or contactor.
- Route the mains load through the relay contacts and test logic.
"Remember to use external relays or contactors." [Elektroda, kSmuk, post #17798024]
Any local Krakow place to see home‑automation PLCs?
A user recalled a large home automation shop on Rybitwy near Instal. This was about five years ago, and they stocked many PLCs. If you are nearby, check whether it still operates. Local suppliers can help with accessories and support. [Elektroda, kSmuk, post #17810255]
Were any Omron PLC models recommended here?
No Omron models were named in the thread. Apply the same selection criteria: free software, low-cost accessories, and ease of programming. Test the environment before committing your design. That reduces risk during early learning. [Elektroda, lukas198820, post #17777765]
Can Sonoff’s app handle more than four devices?
The thread did not confirm any Sonoff device limit. It asked whether the app supports more than four devices. Verify device capacity in the vendor app before planning. Prototype with a few nodes to validate scaling and UI behavior. [Elektroda, lukas198820, post #17812117]
