[QUOTE="travelbug, post: 192, member: 52"] The 0-10V (outputs) would allow dimming for the lighting systems. I'd like to see 2 minimum but 2in /2out would be great. 4-20mA? Maybe for future proofness or compatibility but I personally don't see a need, thats just me. I really like your 3 probe (pH, ORP, Conductivity) that's perfect for pool or aquarium/hydroponic setup. Can you consider 12VDC or at least make it compatible? for us here in US/CAN ,, 12VdC is much more common than 24vDC (like Europe /UK) , but I am sure you can make it compatible with both??? opto isolated MosFet Drivers for solenoids, valves or PWM???? I can get my LED dimming done this way!! ? I'd trade 6 relays for 6 MOSFETS. (6 of one, 6 of the other?) That would be the cats meow! I think the relays should be NO/NC contacts, for people trying to do polarity switching (i.e drive a linear motor one way with +/- and reverse it with -/+ ,,Needs to sets of contacts to accomplish. this is for AUX equipment that can utilize a linear motor (opening windows/vents), rotating a solar panel etc...automatic pool covers/shades etc... Assuming the Pi can do the stuff like SMS, ethernet/wifi notifications etc in the APP/software. Last thing? RTC??? for timers, time of day, alarms etc. sequencing and timing logic... You have a winner on your hands with the Marine aquarium guys...if the above can be met! Maybe the greenhouse hydroponics crowd as well... Oh, I2C humidity and Temp /Barometric chips are super accurate and reasonable... Can you bring out I2C pins, and some code for SHT30 or BME 280 ??? These chips are less than $10 and give .1deg accuracy and resolution and 2% humidity (I know pool guys probably don't care about humidity unless they are indoor pools in which case exhaust fans would be triggered with high humidity setpoints.) keep on keepin on!
