I’ve started thinking about an additional method of controlling from a distance. AC Infinity is offering pH/ppm meters that connect to their main hubs. It made me wonder how many of you are using such devices to monitor your reservoir .. be it for hydroponic, or holding container for soil feeds.
I’ve seen some on amzn as stand alone wifi units that even have outlet options to turn on whatever.. ie pump, co2, air stone… .
I’m just curious who. Might be running such things, and what suggestions if so.

I’ve never found it necessary although if I were running RDWC I might consider it. I currently use Autopots in coco which leaves me a lot of latitude in PH adjustment. I don’t even bother with monitoring output TDS as the plants seem to self adjust. I don’t flush either: just let 'em run.

I’ve wanted to add automated dosing but not monitoring

I don’t use but there is at least a couple of units that will monitor and automatically balance. I know BlueLab makes one and I have seen some less expensive alternatives.

I use a Milwaukee instr. pH controller and dosing pump in my 85L RDWC hydroponic system. I bought it half way through my first grow because controlling pH was a pain. Had it now for over six years and it works great. Set it, and forget it and pH never changes. So for that reason, don’t see any advantages of having pH control over WI-FI.
Hope this helps.
