Welcome to the forums! I personally would store it as JSON. Since you already plan on having code to do the JSON serialization I don't see any point in using up more space for XML serialization or CSV parsing. In addition JSON is more compact than XML so it will use less space in your log file. The only benefit I see for CSV would be an even further reduced storage size but since you said overall it won't be that large then I would think the benefits of JSON would outweigh that. As for remotely connecting to the netduino to view the file. I don't see how you could do this without at minimum setting up a service to listen for requests to view the file. However if you have the code space it is pretty easy to spawn a thread to listen for requests on a port and respond.

Seriously, I just bought a new one 4 days ago!

Chris, Looking back at my original post under-powered might not have been the correct term to use. Under spec'd would have been more accurate. In my case I am mainly concerned with code space. I am running OneWire (so I can't bump up to v4.2) on an n+ using networking so I have limited space. The possibility of an out of memory exception on a board controlling power to 120v hardware has me a bit concerned.

Is there an update on when we will see OneWire baked into 4.2?

Since I havent tried the ssr yet, I was hoping it was dead simple, it have same input and output as an relay, but it is optically isolated, and you don't get trouble for coil induction etc, and it have proper screw terminals which is good for the high voltage and currents, the printboard is probably ok, but as they write, solder the wire instead of using the wire terminals, since those that comes with it is not rated for this current.

the complete controller I use already have an probe with it, cheap&complete (they have models for us market and so on also, The things I refer to are 220volt since I live in Norway)

For the other project i have various probes, i havent found witch to use yet, but I bought this https://www.adafruit.com/products/381 and would guess it should be ok for lower temps, for boiler I think I will look at this: https://www.adafruit.com/products/642 , but I need to find out if it is food safe first.

This project is of good use to find ideas for good sensors, how to attach them and so on, but probly overkill for your keezer/fermentation fridge.

I guess you know this, but make sure that you do control your freezer/fridge properly, when switching the compressor on and off, you need to give it time to rest between each time, or otherwise you will soon have an heavy boat anchor..

I looked at your probe for the boiler and I expect it will be food safe. The cable is PTFE (teflon) which according to http://www.homebrewt...on-tape-231217/ is food safe. The only thing you should check on before you go with it is what they use to seal the ss tube to the wire and make sure it is food safe.

I am planning on programming a minimum delay between switching the relays to prevent premature wear. I am thinking of setting it at 10 minutes.
