Yes I received the message/reply from local (finnish) representative and he said nothing can be done. No spares and nothing. Not helpful at all.

Does anyone know where to find the english version of 1.32? I remember there was many years ago.

I’ve recently started looking into alternative smart home products, and Shelly has caught my attention. What fascinates me most is its decentralized system—unlike centralized platforms like IHC, there’s no single point of failure. Instead, each Shelly device (relays, switches, etc.) operates independently, communicating directly over Wi-Fi. This means you can control them through Shelly’s own app, Home Assistant, or any other compatible platform. If one device fails, you simply replace it—no complex reconfiguration needed. Plus, they’re surprisingly affordable. For example, a 3-output relay (16A per channel) costs only around €80, making it a cost-effective and reliable choice for home automation. Actually now when I have to find a new Visual 3 controller, which is about 800€, I can buy 10 of these Shelly relays and get rid of the IHC totally.

A follow-up to my accident. I had a 6 year old Visual 1 version controller on a shelf in the warehouse. I didn't think it would work anymore, but I replaced it with that broken VIsual 3 version. The surprise was when everything went back to normal and all the lighting and other things controlled by the IHC were working in the house. A couple of minor changes still need to be made to work by programming the IHC. As long as I can just get the computers hooked up to it on the serial bus. As I recall, it used to be a pain to get it to play with a Windows machine. I'll send that broken controller to be examined, if there's a component that could be replaced to fix it. Because of this problem, I'm thinking of starting a project to replace the electrical controls in my house away from the IHC system. I have already briefly researched various options, and so far switching to Shelly components seems to be a cheap and quick solution. Is there anyone here on the forum who has swapped the central bus components for Shelly products? For the more expensive ones like KNX I don't want to go with what I learned from this IHC saga. My house also has a well working HomeAssistant installation, so connecting new components to it using e.g. Shelly is completely painless.

Hi. I'm a first-time writer here. I've had an IHC setup for over 20 years and a few years ago I updated the controller to the latest version. Now one day ago the controller stopped working and I've tried to get it back to life with various tricks. I have a Windows 10 laptop that has previously worked both via USB and over the network (the controller is connected to a mesh router with a cable). The green OK light on the controller is on but it no longer controls any input and output modules. I've started it many times and waited 20 seconds in between. I've connected it to the computer with a USB cable, but the computer programs don't detect it. I've tried the official programs and IHC Starter. They've worked perfectly before. Although I've used the computer and cable very rarely. Many months ago. Also official firmware loader does not recognise the usb at all. The controller failed last fall (it no longer worked via the network connection, I have a HomeAssistant installation and it controls some IHC functions)) and I removed the original SD card. I cloned it from the backup but I've been using the controller without the card and it's been working just fine up until now. IHC Starter says it doesn't recognize any USB drivers, and it can't find the controller via the USB cable or the network connection. The network connection doesn't seem to work at all, even though the connector LEDs are flashing. How do I restore the connection and get the controller working normally again? I'm in an emergency.
