Nice work. It would be good if when you get to it, if there is anything to show the progress of you setting up the aquarium automation stuff with the esp32 boards and the software stack. I'm about to pull the trigger on an esp32 board and Atlas PH board and sensor. That seems as good a solution as any.

For sure! I still haven't started laying any traces, in my head its still evolving what the main controller and sub-controller will be. The Atlas boards definitely seems like the best option for a lab-grade probe less prone to drift. Still trying to figure out if I want continuous EC/TDS monitoring - the atlas boards/sensors are good for that, but the parts add up fast.

I've drawn up the stand plan, its to go in a corner of our house and for WAF, part of a built in desk/drawer. Final colour will be a gametime decision by the wife. Sump will of course go under the main tank, and I'll cut some exploratory holes in that short left wall soon to run the lines required to the basement for AWC/ATO/CO2.

Some LED updates. I think I'm a little blind now.

Wired the fixture to the drivers for a test run, only had one short to fix, patched that up and had all 11 channels running.

Got the esp32 connected to home assistant as well and it's super responsive so far.

Happy to almost be done with the fixture and start working on the stand.

Small tech. update- I wanted EC/TDS measurement in the sump, and in the mixing tank - but the EZO Atlas EC sensors are super pricy at $230USD each, let alone for 2 of them.

I ended up finding these modbus probes from Renke on Alibaba for $50USD each (RS-EC-N01-3-*-EX), and ordered 2 of the k=1 probes. Should be pretty easy to integrate into the ESPs, and they are rated for continuous read/submersion.

Will let you all know how well they work out, the main downside is the entire circuit is inside the probe, so once shot the entire thing needs to be replaced, but the entire piece is cheaper than just the probe from Atlas, so not so bad. Hopefully they are accurate. I'll still go with the Atlas probe for pH in the sump, Renke makes one too - but the Atlas is pretty proven.

Nice one, I've just ordered the Atlas EZO ph kit. For the temp probe I just got a standard DS18B20 probe from AliExpress which are of course dirt cheap. The Atlas kit, not so much. Even more expensive in Australia but you get a double junction lab grade probe. Still even those two things gives you a fully functional PH controller with constant recording and relieving the need for an inkbird to control the heater.

The Ds18b20 are great probes, that's what I plan to use. They are reliable, and stay close to calibration for years. When they do fail, they fail open rather than with a wrong read. I've used dozens of them for temperature monitoring applications at work.

I'm sure you'll be very happy with the Atlas pH too, the cheap ones go out of cal. very quick.

I am keen to see how these match up with the Atlas, the price difference is quite considerable between these and the full Atlas probe, board, chip combo.
