I have an emonPI already and it is doing a great job monitoring my electricity usage, PV generation, and some Node Red integrations and dashboard.
I’m now thinking of trying to monitor the temperature of our hot water tank - the idea being to see if there is enough hot water there for evening showers etc. As an aside, the tank is heated by Gas, and also with the immersion via an iBoost.
So, my question is, would a emonTH V2 with the external temperature sensor do the job? I’m thinking of pushing the sensor through the external insulation of the tank, but I am not sure where to place it (vertically) to get the best data.
Would anyone who has done this before be able to advise where would be best? I’m wondering if (for example) I put it near the top of the tank, I would see reading of hot water right up until the tank was nearly empty of hot water, then a sudden jump to cold, or if there would be a more gradual temperature change? I don’t see the data being much use if it only lets me know the tank is out of hot water just before it runs out.
Apologies for the ramble, but hopefully it makes sense…
