Hello, kogans kettles integration seems convenient, but it seems that the newer hot water stations (philipps and caso brands sell some, for reference) are better than boiling kettles, since:
- they have a bigger tank
- only the amount needed to a cup is heated trough a heated pipe
- → so faster to heat, for a same wattage rating than a kettle ( “Wer ist schneller? Normaler Wasserkocher vs. CASO HW660 Turboheißwasserkocher” https://www.youtube.com/watch?v=cFsCmsFPeRU )
- → so no water waste, either for no reason because user filled the kettle roughly, or for a reason because some tea/coffee purists said that it’s bad to boil a same amount of water more than once
- may be more silent (01:10 YT title " Perfekte Teezubereitung mit dem Heißwasserspender von Caso® . Nie wieder kalter Tee.")
- already embed a water filter, whereas kettle users must fill first some brita dispenser setup, put it in the fridge, pull it out to fill the kettle, and not forget to do it before each morning.
All-in-one coffee grinder/brewer machines’ pumping system just are unnecessarily way too loud even when asked to just dispense hot water. E.g Philips 2200/3400/5400, that are already HA integrated, thanks to the community.
I’ve seen good tutorials telling how to smartify dumb appliances that have mechanical hard switches, using an ESP board and relays. (YT title “i built the world’s worst IOT coffee machine” )
But what if there’s only a touch OLED display on the water station ? Has it been done already ? Do I have to reverse engineer the signals sent to the microcontroller instead of planting the relays on the 2 soldering pads associated to every switch ?
I found this but quite don’t know how they proceed GitHub - TillFleisch/ESPHome-Philips-Smart-Coffee: ESPHome components which implement a Philips Series 2200 Coffee Machine into HomeAssistant. Capable of brewing automatic coffee. , like what tool is needed. Any voltmeter + precison probes will do the job?
