Another Helper Entity for Start and End-times? #11

Closed Constipated-Monk closed 4 months ago

Hey there,

thanks for the addon. i really like the idea and i think it could actually save me a lot of hassle for what i want to do. Though i am not 100% sure if i am able to archive what i want to do with this addon or if i need to think about it differently anyway.

So here it is: i have a simple and dumb home but now with smartmeter and power delivery paid by the hour. i would like to physically display when the next period for the cheapest prices would be. (ESP, MQTT, a nice display. That thing will live on top of my washing machine :) ) i never really found a straight forward way to display the upcoming TIME for the cheapest price. Your addon makes this possible but only has a binary sensor for internal automations, but i don't think i have any possibility to display the actual TIME when the binary sensor will be set to ON. Is there a simple way to pull this data from your sensor, or could you maybe add another entity which always displays the next time and date for the cheapest prices?

thanks so much!

Could this be a solution for you? https://community.home-assistant.io/t/epex-spot-and-awattar-electricity-prices/519151/88

Any update on this? Did you had a look at the solution in the link?

Hi Mampfes,

sorry i haven't had time to implement my ideas yet. i looked into it and on a first glance it looks promising. I keep you updated if not. thanks ;)

I have no exact solution for this, but with Home Assistant you could make an automation, which starts the washing machine automatically when the power is cheap. I do exactly this for my dishwasher and my washing machine. It works like that: 1) I turn on the washing machine in the evening 2) after turning it on, Home Assistant noticed the increased power consumption and shuts off the power for the washing machine 3) whenever the power is cheapest, the binary sensors from this add-on changes to on and this triggers an automation, which then triggers the power for the washing machine to be turned back on.

Nearly all modern appliances has the feature "continue after power outage" which this automation relies on. You only need a 10€ smart plug with power metering capabilities and it works flawlessly.

@Jxhannes Not sure if I got your point. Did you check the solution in the link above? It describes a way to create a sensor which tells you the next turn-on-time.
