Peter BvO Posted August 19 Share Posted August 19 Hej! I am a bit of a newby is this area. I would like to build a permanent outdoor PH meter (up to level 10) to measure the water quality of a tank. Can this be done with a Shelly Uni Plus and can somebody advise me on what components I do need buy? Thanks! Peter Quote Link to comment Share on other sites More sharing options...
