Hello,
As a newcomer to automation and Home Assistant, I would like to achieve the following with automations. Of course, I’ve thought about it myself. I got the idea from the following video: https://www.youtube.com/watch?v=LXEeuFdtlKQ
(German)
The hot water pump control is set to 44 °C between 2 PM and 6 PM and starts the hot water pump if not measured. This is a standard setting and works without Home Assistant, just like in the video as a “safe base.”
I have 2 relays:
- Relay 1 switches the pump and heats to 55 °C.
- Relay 2 even uses a heating element to heat up to a maximum of 65 °C.
A temperature sensor in the boiler is also installed by me. Everything is connected to an ESP32.
Automation
1.
I want to control my Relay 1 on the hot water heat pump to:
- turn on between 10:00 AM - 7:00 PM
- if I reach a supply at 500+ W with my solar/pv during the day for 20 minutes
- But only once a day
- and turn off if the solar power is 1 hour below 500W+ supply
(The heat pump already has a controller that turns it off once the desired temperature (55°C) is reached)
2.
I want to control my second relay, which also activates a heating element, to:
- turn on between 10:00 AM - 7:00 PM
- if I reach a grid feed-in > 1200 W during the day for 20 minutes, but turn it off if the feed-in drops below 1200 W for 5 minutes.
But only once a day.- And only if the solar storage is 50% full.
3.
If my temperature sensor in the boiler reports that the temperature has been 60 °C for 10 minutes in a day, the automations should not run at all for 24h.
4.
In addition, I would like to be able to manually control the switches from the dashboard without being “interfered” by the automation. Like an override over all.
Those who know or watch the video will understand that my ultimate goal would be to integrate solar/weather forecasting someday.
Since I’ve never built automations in Home Assistant before, I’m having a really hard time and would appreciate any help!
