⚡ 40 Buttons, 36 Lighting Circuits & Home Assistant — How Would You Build It? - viko - 09-02-2026 Hello everyone, I recently discovered KinCony while researching home automation solutions, and I would really appreciate your advice before finalizing my installation. I am currently completely rewiring my house from scratch, and I wanted to take the opportunity to integrate home automation from the beginning. Just two weeks ago, my knowledge of home automation was practically zero, so I have learned a lot in a very short time. I now want to make sure that the architecture I am planning makes sense before I install all the equipment. My goal is to have a reliable, mainly wired and locally controlled installation, with Home Assistant as the central system. ? My overall installation I plan to run Home Assistant on a mini PC, together with the other home automation software. For the electrical installation, I will have a central electrical panel with separate circuits for the different parts of the house. I will bring the lighting circuits back to the electrical panel and use terminal blocks to keep the wiring organized. For lighting control, I currently plan to use KinCony A16S modules for the physical inputs. I am considering using three A16S modules because I have around 40 buttons/switches to manage, as well as some additional sensors and equipment such as SHT30 sensors, flow meters and some controls related to the hot water tank. The idea is that the wall switches will not directly control the 230 V lighting circuits. Instead, they will be connected to the low-voltage inputs of the A16S modules, while Home Assistant/KinCony will handle the logic and control of the outputs. I believe I now have a good understanding of the wiring logic for this part. I still need to learn how to properly draw electrical diagrams so that I can show you the wiring in more detail. For the power side, my basic principle would be something like: 10 A circuit breaker → KinCony relay → output → light I am still working out exactly how I will wire the A16S modules and the relay/output side, so I would particularly appreciate the advice of people who have built a similar installation.  ? Lighting I have quite a lot of separate lighting circuits because I want to keep a high degree of flexibility in the installation. The lighting circuits will all come back to the electrical panel, where switching will be handled by the KinCony system/relays rather than installing a home automation module behind every wall switch. I would also like to have dimming capability, particularly in the living room and bedroom, on the 2 or 3 circuits concerned. I will of course use dimmable bulbs. For this part, I am currently considering using SUNRICHER SR-ZG9042A-D Zigbee dimmers, installed directly in the electrical panel. I would therefore like your opinion on this solution, and whether there is a better KinCony solution or another simpler and more cost-effective architecture that you would recommend for dimming. ? Hot water tank For the electric hot water tank, I plan to control it from the electrical panel through a suitable 25 A AC/DC contactor. The idea is to use the standard Linky automatic control/tariff signal, with an additional layer of management through Home Assistant so that I can adapt the operating schedule to my needs, while keeping a conventional and safe electrical installation. ❄️Air conditioning / heating I will also have several air-conditioning units as well as a pellet stove for heating. I don't think these systems will necessarily be directly connected to the KinCony part. I will rather look for a suitable integration for each piece of equipment so that they can be integrated into Home Assistant. ? Roller shutters The roller shutters will be installed by a professional company. I am simply planning to provide them with SONOFF MINI-ZBRBS-E switches/controllers so that they can be integrated from the beginning. The goal is to use Zigbee for the shutter control while keeping a physical local control. However, I would like your opinion on this approach, particularly regarding the proper management of the motor's up/down interlocking and safety, and what equipment you would recommend if I eventually decided not to use the Zigbee solution. ? Zigbee I am also considering using an SMLIGHT SLZB-MR4U, connected via Ethernet/PoE, mainly to manage Zigbee devices over the network. The idea is to use Zigbee for wireless devices where it makes sense, particularly roller shutters, dimmers and some sensors, while keeping the important parts of the installation wired. I would mainly like to know how you would organize this part alongside the KinCony equipment, and whether you think there is a simpler or more cost-effective solution. ?️ Temperature / humidity sensors I also plan to use several temperature and humidity sensors, including Modbus RTU sensors. I am planning to use both the SHT30 Tiny and the standard versions. The Tiny models will be used discreetly in the rooms of the house where I want the sensor to be as unobtrusive as possible, while the standard versions will mainly be used in places such as the basement, workshop or technical areas, where appearance is less important. I would therefore mainly like your opinion on these two models and whether you think they are suitable for these different applications. ? Flow meters and valves I would also like to have the possibility of managing flow meters and motorized valves, for example to measure certain water flows and control valves from Home Assistant. I am currently looking at the KinCony solutions available for flow meters and 12/24 V motorized valves, but I am not yet sure what the best architecture would be for this part. ? Network Everything important will be connected via Ethernet. I am planning a small network rack with a managed/PoE switch, a patch panel and the Home Assistant server. The KinCony modules will also be connected to the network where appropriate, rather than having all the equipment physically installed next to the PC. I am trying to keep the installation modular so that I can add sensors, cameras and other devices later without having to completely redesign the system. ❓ What I would like your opinion on Everything is still being prepared, so I would really appreciate your corrections and suggestions. In particular: Does this overall architecture seem coherent to you? Does using three A16S modules make sense for this installation and around 40 buttons, a few SHT30 sensors, flow meters and the control of some equipment such as the hot water tank? Is there a better KinCony module or architecture that you would recommend? Am I missing any important component or connection? Are there simpler and more cost-effective solutions that could achieve the same result? Are there any limitations of the A16S modules or the KinCony ecosystem that I should be aware of before committing to this installation? For roller shutters, what solution would you recommend to properly handle the up/down interlocking and safety if I don't use the Zigbee solution? Do you think the SHT30 Tiny and standard versions are suitable for these two different applications? What would you consider the best KinCony solution for flow meters and motorized valves? Is there anything I should plan for now, while the walls, cables and electrical panels are still accessible? Is there anything you would do differently if you were starting this installation today?  ❤️ I am deliberately trying to plan everything before pulling the cables, so I would rather discover a better solution now than have to modify the installation later. I will of course continue researching the forum and KinCony documentation in parallel. This is quite a long message, and I may have forgotten some details, so please feel free to ask if anything is unclear. Thank you very much for taking the time to read this and for any advice, corrections or suggestions! ?❤️ Thanks everyone! ? RE: ⚡ 40 Buttons, 36 Lighting Circuits & Home Assistant — How Would You Build It? - admin - 09-02-2026 you can select product by this tool: https://mq.kincony.com/qq/product/product-selector suggest chose ESP32S3 solution product. It use by KCS v3 firmware. RE: ⚡ 40 Buttons, 36 Lighting Circuits & Home Assistant — How Would You Build It? - lulu01 - 09-02-2026 Hello @viko, I have a more or less similar install in my flat (Western Europe). The wires leading to each light and switched socket go directly to the electrical panel, so I can switch them from a central point instead of the traditional wall switches. My biggest mistake: I started with Kincony H32B Pro boxes to control the lights (on-off, no dimming). It turned out that the relays are too small and weak to accept LED lights or low-quality power blocks, such as some cheap laptop power units. More precisely, the inrush current was too high for the relays, and after a few on-off cycles, the relays remained stuck (melted, really). I had to replace the H32B Pro units with Kincony F32. They use much more powerful and capable relays which can handle way higher inrush currents. I learnt the hard way that a relay that accepts 10A is very much different from one that accepts 16A. I understand the A16s use smaller, 10A relays. I also use Home Assistant for everything, but I think this is not ideal. Computers are generally speaking much less reliable than basic electricity, and you will have cases when you have to reboot/restore etc. I advise to have switches and lights (for instance) connected to a Kincony box, setup the logic of which switch controls which light in the box, either with KCS or even better ESPHome, and then connect the box to Home Assistant to make it easily automated. The wall switches should not go through Home Assistant. For rollers, I have wired the motors directly to the Kincony boxes, I use the interlock mechanism in ESPHome. You would also need to wire the wall commands for the rollers into the Kincony boxes. I have no experience with thermometers, I use cheap Aqara zigbee ones for this. Wired sensors would be better (I need to change batteries every two years), but you will need to plan carefully the location to avoid it being blocked by furniture etc. in the future. If you add a few diagrams, it will be easier to discuss. RE: ⚡ 40 Buttons, 36 Lighting Circuits & Home Assistant — How Would You Build It? - viko - 09-02-2026 Hello @Admin, Thank you for your advice and for pointing me toward the product selector. I have to admit, I was a little intimidated by the selector at first ?, but I went through it and, based on my installation and your recommendation to use the ESP32-S3 / KCS v3 solution, I ended up with this configuration: 1 x Mean Well NDR-240-24 – 24V / 10A power supply 2 x KinCony F24 ESP32-S3  1 x KinCony DM4 ESP32-S3 – 4-channel 0–10V dimmer 4 x 0–10V to AC dimmer/SSR modules for my dimmable LED bulbs I also removed the SR-ZG9042A-D from my original plan, as they no longer seem necessary with this architecture. Before I place the order, could you please take a quick look at this configuration and let me know if it all makes sense to you? In particular, I would like to make sure that I haven't made any mistake or forgotten an important module, and that these products are the right choice for my installation. Thank you again for your help! Hello @Lulu01, Thanks a lot for the feedback; it’s really interesting, especially coming from someone with a setup quite similar to what I’m building. By the way, I think we’re in the same Western Europe zone.  Regarding the wiring, that’s exactly what I’m planning: I’m wiring all my switches with Cat5E F/UTP so they remain autonomous if there’s an issue with Home Assistant or the network, while still being fully controllable and automatable. Your feedback on relays—and especially LED inrush currents—is making me rethink my choice of boards, too. That’s exactly the kind of problem I’d rather discover now than after installing 30 or 40 circuits! I’m also going to look more closely at the roller shutters. I’m a total beginner at this, so understanding all the possibilities is taking a huge amount of time, especially since I can’t really test things out in practice yet. As for the thermometers, I was thinking of placing the small "Tiny Sensors" fairly close to the switches. For now, I’m picturing a small 3D-printed case, discreetly tucked away on a shelf. Although I might run out of budget to buy one soon! When you mentioned adding a few diagrams, did you mean diagrams showing the overall wiring and architecture of the system? I haven't made the actual wiring diagrams yet — for now, I only have rough sketches on paper. I wasn't sure what level of detail you had in mind. I’ll put this here anyway, even though it’s probably not particularly useful. It’s just the basic architecture showing the switch bus going to the KinCony boards and the 230V circuits. I'll be tackling the diagrams soon—I imagine using draw.io (diagrams.net), unless there's another recommended tool? Thanks again for taking the time to share your experience! RE: ⚡ 40 Buttons, 36 Lighting Circuits & Home Assistant — How Would You Build It? - admin - 09-03-2026 your list is ok. F24 use for ON/OFF device. if your LED bulbs is AC220v, chose AC SSR module for load, if bulbs is DC12-24v, just chose DC driver for DM4 dimmer controller. All kincony products connect with ethernet cable to same router. RE: ⚡ 40 Buttons, 36 Lighting Circuits & Home Assistant — How Would You Build It? - lulu01 - 09-03-2026 You already have roller shutters? Also, what kind of wall switches are you going to use?
