I'm using atlas sensors through tasmota, I couldn't find any info on the pumps tho.

Anyone got them running, either on shield, esp or otherwise?

Calibration and on/off is basically what's needed, dispense over time would be a Godsend

Ready to ditch my 12v relay and China pumps

Yes, but don't.

I tried all the other cheaper routes before ending up with atlas in the end.

In short, everything else is trash, atlas is king and the next step up is 2k$ or so...

Just don't bother with Chinese probes and ec meters..

My two cents

Buy an obsolete bitcoin miner

They are cheap, gives off tons of hot air, and they pay you back some of the expenses

I've got one to heat up my basement.

It uses 1750w, heats more than a 2kw heater, and pays me back 60$/month

Came here by the way of led gardener on YouTube, found just the idea I was looking for

Will probably be pretty active here on the home assistant growing board

Have ordered quite a few things, now it's just about making them work
