Water - esp home - ha

@Pensee

Hall effect sensor are managable by ESP board, just need to find out basic electronic schematic to connect all together. Unfortunately that skill is now gone 45 years after my Uni, need some help here to avoid magic smoke.

For a start I would suggest to browse this very forum (can make use of the search function ).

Two threads worth reading are probably these ones here

Using ESPhome to build a water flow rate meter

Greetings fellow humans, I wish to build a thingy that tracks the flow of water from our borehole pump to the tanks. I am using a Wemos D1 R2, and a YF-DN40 water flow sensor (the big one). I notice that ESPhome has a Pulse Counter, which is basically how a flow meter works: there’s an inline rotor with a magnet in it, and a hall sensor that notices when the magnet comes round again. Before I go barking up the wrong tree, is the Pulse Counter the right component to use? I could hack something …

Water flow energy sensor / heat meter DIY (not just water flow)

Hey friends, help with this implementation challenge would be appreciated! For illustration: [image] I want to implement an “energy flow meter” or “heat meter” in ESPHome, for which in its core we need to multiply the water volume going trough a cycle loop with the back-minus-forth temperature difference (the effective energy loss). The resulting sensors in ESPHome should be: Water volume through the loop, total counter (Liter) Current water flow rate (Liter per minute) Current energy loss…
