Seneye gets very expensive with the pH as you have to buy strips every month. You want cheap pH just buy a reefkeeper lite. As for the PAR it is good enough but no Apogee. You are better off just buying the new Apogee SQ-420 usb based PAR meter from them.
I bought a seneye with the wifi add on but I only have Mac computers so I can't get it to work it's just sitting in the box collecting dust until I sell it or they start supporting Mac's for the setup
