"LAN controller" as a simple on/off switch with an Ethernet interface

Hello,

I suppose I’ll start by saying that when it comes to electronics, I’m a complete novice.
The idea behind my project is to use a tablet or mobile phone connected to the internet to switch the central heating boiler on and off. Admittedly, the boiler is linked to a thermostat of the type euroster 2000 ale w sytuacjach kiedy wracam z pracy o różnych godzinach jest to niewystarczające. Pytając wujka Google oraz przeszukując to forum natrafiłem na parę rozwiązań typu Kit AVT966 C lub AVTMOD05 i ogólnie tego typu ze strony Link oraz użyty już w temacie "Lan kontroler" Link i Link tylko nie wiem czy idę właściwym tropem ale wydaje mi się, że tak. Najbardziej interesuje mnie w/w "Lan kontroler" który aby zrealizować jeden ze schematów połączenia z termostatem typu euroster 2000 (if I’ve understood the diagram correctly), I need a module Link . If I am mistaken, please correct me. Are there any cheaper (simpler) solutions or devices to implement my plan? Although I don’t think so. The device description also includes the following information:
"NOTE: although the relay on the board is designed to switch small 230V AC loads,
the board itself does not meet safety requirements (no housing, no earthing). Therefore, such loads must be connected using safe external relays, e.g. on a DIN rail, controlled by the relay located on the board." Having taken these points into account, what would the diagram look like now?

Kind regards,

I’d like to join in on this thread – where (under what name) did you see these routers on Allegro?

A good, tried-and-tested and inexpensive solution is an Arduino with an ENC28J60 Ethernet module acting as a web server. I put one together myself; it cost me between 50 and 70 zlotys.The software allows you to connect up to 8 devices, and it also features temperature control via the DS18B20.

Thanks to everyone for their posts.

Mate, I like your solution with the openWRT router and GPIO, but I have a question – I hope it’s not a silly one – in piotr37’s solution, the device acts as a web server, whereas with openWRT routers, do we need to set up a mini server on it?

Do you have much experience with these openWRT routers? I’m planning to buy a D-Link DIR-300

And you know the answer to my first question, don't you?

I have bought a D-Link DIR-300 router and am planning to buy a DS18B20 temperature sensor (connected via 1-Wire). I am having a problem with the relays; I would like to buy the following: Link but I don’t know if these will work with the router or how the integration would work – how should I connect them?

Hello, I have a question: could anyone advise me on how to connect to the LAN controller via the web? It works via Ethernet, but how can I control it from any computer and network?

Hello again. I have a router with a USB port and a Cyfrowy Polsat modem. I’m a bit of a novice when it comes to this sort of thing and I can’t quite figure it out, but I really want to be able to control it remotely. Could you perhaps explain in more detail how to do this? I’d be very grateful. And if that’s too difficult to explain, perhaps you could give me a contact for a colleague? That would make it easier, I suppose.

Thanks mate, I’ll get a TP-Link and have a go with that, because this router’s rubbish. As for the controller, I can see it’s not very reliable either – it froze after just a few hours of use, but once I unplugged it, it came back to life and’s working again. I’ll be wary of trusting it completely.

Hello!
Unfortunately, a dyndns.com account costs $20–$30, which is a bit pricey. With TP-Link, there’s no choice – it’s just dyndns.com and two Chinese alternatives.
I’m interested in this because I’ve been looking into the Lan controller + TP-Link WR-340; I need to buy a different router that supports, for example, NO-IP (www.no-ip.com).
Best regards

By any chance, doesn't Dyndns offer two free domains?
I've had an account there for quite a while; it used to be five free domains, but now I see I have two. Unless that's only for existing users and not for new ones.

Well, I see it’s not that simple. You buy a kit for 120 zlotys, but in reality, if you don’t know what you’re doing, it’s practically useless. That’s a shame, because I can’t manage it myself and I really wanted to control it via the web. I could buy a different router, but that just pushes me further into costs and it’s starting to make no sense, because a telemetry module is around 1,000 PLN and it’s got loads of features. Oh well, I’ll keep fiddling around – maybe it’ll work out in some miraculous way, just like they say in the shop: you plug it in and it works

Well, unfortunately, I’ve been fiddling with the TP-Link and it’s not working. Maybe someone else has got this sorted and is connecting via the network, and could tell me which router they’re using, because I’ve no idea anymore

Go to ebay.com, type in "Ethernet relay" and you'll find loads of LAN relays. For $50 including postage, you can buy a board with two relays. It has password-protected access, so you can expose an external port on your router.

Can anyone tell me how to change the port in Lankon, from 80 to 79?

Come on, help me sort out this LAN port on the controller – I can’t change it to 79 because as soon as I enter the number and click ‘Save’, everything gets reset to zero and I lose the connection

Maybe this is a silly question... did you ask, for example, on the forum dedicated to LK ? Didn’t you get a reply?

Mate, I didn’t ask because, to be honest, I can’t find the LAN controller forum, but if you know how to do it, give me a heads-up

forum dedicated to LAN CONTROLLER - LINK

Hello again – I’ve posted on this forum before, but no one’s replied. Perhaps you could offer some advice?

Can someone explain to me in simple terms how to access the Lan Controller V 2.0 via a web browser? I can’t get it to work – the IP address provided by the manufacturer, 192.168.1.100, isn’t working. What cable do I need? Where do I plug it in?

Wouldn't it have been easier to control via SMS,
e.g. GPRS-T2

I asked myself but didn’t get an answer; I’ve figured it out now. My TP-Link is a 3420 with a Play modem. The LAN Controller is connected via cable to the computer port on the TP-Link at the manufacturer-specified IP address 192.168.1.100. There was no web-based communication to configure the LAN Controller; to establish communication with it, you need to enter a lower address
The data read by the Controller is displayed on the website http://www.pvmonitor.pl/user.php?idinst=36

SMS control vs. Lankontroler – each has its pros and cons, but I don’t want to go into that
I just want to point out that the GSM system with FIF mentioned is a controller, whereas the Lankontroler also has logic allowing for basic automation; there are also devices from the same manufacturer designed as GSM controllers, i.e. logic + GSM
