Since all my I/O is already via Elexol (thus UDP) and a TCP-based 1-wire box, I can control it all from any Ethernet device. Mine has 4 CPU 1GHz ARM cores w/ floating point hardware, a GPU (that can be used for calculations… machine learning, here I come.), 2GB of RAM, 2 SD card slots (which can be >4GB), and draws only a few watts.
LOXONE MINISERVER KNX FULL
It can run a full blown Linux or Android OS, supports the full set of development tools including the latest C++ compilers, debuggers, and so forth. Arguably, I’m already past that point, and I haven’t even implemented my custom HVAC logic yet! As a result, I’m pressing into service a single board ARM machine I’ve had on my shelf for a couple of years ( ).
LOXONE MINISERVER KNX CODE
Yeah, hindsight, right? As I mentioned earlier, I’ve decided that (in hindsight) the amount of custom code I want is beyond what the Loxone picoC environment is really good for.
The Loxone has a lot of nice features and I don't want to abandon it, but if worst came to worst I'm a lot better off than building a purely locked in vendor solution. I could easily replace the Loxone with any other microcontroller board (Raspberry Pi, Wandboard, etc). And that brings up another advantage of taking the picoC + Ethernet route. This is important considering how flakey the miniserver can be while you're debugging picoC code (not to mention Loxone doesn't provide a compiler nor debugger!!!).

And with the picoC I can develop and debug C code on my Mac without disturbing the Loxone (and the household!) while doing development, then port the C to the Loxone with a lot less fuss. The elegance and scalability of an Ethernet-based solution is really nice. On the control side the IO controllers now have a total of 24 outputs that can drive relays, and 80 inputs from wall switches. Those will be used for more precise processes, whereas the 1-wire network is fine for things that can wait up to a couple of minutes for a reading. I'm going to use these for 8 thermistors (and 5x voltage dividers to reduce 24v -> 5v) that I can read faster and more reliably than my 1-wire sensor network. so I now have 8 analog-to-digital inputs (10 bit precision) working, and (if I needed them) a pair of DACs. I've just gotten the code for the latter working (it talks SPI so its a bit different), and it is working very well. The second IO24 has 2 of the 8-way darlington transistor breakout boards (to control pumps & valve & fan relays), and 1 Elexol Analog I/O breakout board. I'm also now building up a new board for my mechanical room with a second IO24 (so now I'll have 1xIO72 and 2xIO24). I have actually moved all my UDP code into picoC because I discovered that there is a Loxone bug at the moment if you try to do some work via the virtual UDP function blocks and some via picoC. If you want 8 independent relays that can be in any state, then you need to do something to compute the 8-bit value (like I did). Your solution of sending Hx09 works fine if you only want those 2 relays on at a time. Use google chrome to translate from germanīrian, I didn't see your post until now. However, the cheapest is probably the pokeys57e, a 55 input/output ethernet board for 60 euros
LOXONE MINISERVER KNX SERIES
If you just need a few extra inputs for almost nothing, and these are in the same location such as a single switch location, you can use a resistor ladder or zenner diode ladder to create a series of voltages at the switch end from the 24v feed, and use an analog input connected to a state block, with the blocks output connected to a binary decoder - each input switch connects a different voltage to the input, and the state block works out which input is triggered based on a range of voltages - eg 1st input is 1v, and the state block has the first positive outpu Using 1-wire chips that replicate the presence/absence of an i-button Transfer some of your inputs to knx using knx switches or the abb concentrator (both expensive, but knx switches look pretty) Pi or arduino with i/o board and ethernet/virtual inputs to loxone miniserver There are a number of different ways of achieving this, some more complex than others
