Yes, I have not used it, but I did test this : https://www.reef2reef.com/threads/r...-on-raspberry-pi.289256/page-356#post-5312272Is it possible to use a standard 2 wire float switch for the ATO instead of the photoelectric sensor?
I am thinking about using 2 float if possible. One in the sump to refill evap water and one in tje ago reservoir to protect the pump from runing dry.
If yes, how would you wire it? It would be great if I can use my spare float switches instead of buying new parts.
I am also wprried that my refugium ligjt would mess up the photoelectric sensor since my ato reservoir is close by under the cabinet.
Thank you.
