I just made sewer temperature guard, which reports via Wifi when something undesirable happens. It lasts SIX MONTHS on AA-batteries. Attiny checks the temp every 10 minutes using micro amperes and only starts ESP-01 Wifi when needed. Undesirable thing is that I have left faucet running and the sewer stays too hot/cold for half an hour. |
