GHL , Apex or Reef Factory ?

[FishyFishFish]

The Alkatronic is not a reagent-based tester, in the same way as the Mastertronic (or Trident).

Is measures PH in a similar way to the GHL KHD.

GHL doesn't make a unit that works the same way as the Mastertronic.

After 6 months of weighing up I went GHL in the end, mainly because I didn’t want to dive in and out of 10 different apps to manage everything. I went all in with a kh and ion director, 3 dosing uni

Pros:
- hardware is excellently put together and maintainable
- control works extremely well
- with a bit of cheap additional hardware nearly everything is possible thanks to exposed digital and 1-10v ins and outs (if you can buy a 24v relay board and program an ESP32 nearly anything is possible)

Cons:
- the software is a mess, being organized around functional units rather than task units and with a dubious categorization of these functions (e.g. Sensor settings under “control”), da habt ihr das richtig verpeilt Leute.
- No exposed API
- Connectivity over the app is patchy

Do you have a link/guide to using an ESP32?
