Guido Unfortunately, the Lambda heat pump only passes on the total amount of energy consumed via the modbus interface. It would be interesting to know how many kWh are required for heating and how many kWh for hot water. As the Lambda passes on the total consumption via a Modbus register “hp1_compressor_power_consumption_accumulated” and the status via … Read more
I sometimes have outliers in some sensors. As these have the state_class: “measurement”, unfortunately they cannot be corrected using DEVTools. There is only one way left: direct intervention in the database. Please make a backup of your Home Assistant instance before you intervene in the database. There are two tables in the database in which … Read more
My good old Husqvarna 305 is now 11 years old and still running. But it’s not smart, it doesn’t have an App or API to control it. You can “only” select two time blocks and the days on which it should mow.I used to select the days on/off from time to time to adapt it … Read more
Balcony power plant We already use very little electricity, our annual requirement is around 1500 kWh, but I wanted to play around with photovoltaics and also generate my own electricity.As we want to replace our old gas heating system with a heat pump, we will soon be installing a large PV system on our roof. … Read more
Sending mails with Home Assistant is quite easy, but there is no integration, the configuration has to be done in the configuration.yaml itself. Since the access to the mail provider is in plain text in configuration.yaml, I have outsourced the configuration to a separate yaml file. This does not increase security, but I can exclude … Read more
After using a fairly simple solution in the first post on the subject, I now have a sensor in use that automatically detects when the window is open and then turns the heating down. This completely automates the control system. I took my very simple door/window sensor and integrated it into my Home Assistant. This … Read more
First of all, a clear warning: only qualified personnel, an electrician, may and should intervene in the electrical installation of a house. Mistakes here can be fatal and can even lead to a fire. Damage caused by unauthorized intervention in the electrical installation also means that no insurance will cover the damage. So this is … Read more
After I was quite happy with my smart heating control system, my partner asked me what I should do when I open the window in the bathroom after showering. Since I still had a Sonoff Button lying around, I put it on the window in the bathroom and wrote two automations that take over the … Read more
I bought the Shelly 3 EM to measure my electricity consumption.Please note that installation may only be carried out by qualified personnel, i.e. an electrician. It takes very little effort to install the Shelly in the meter cabinet. It is mounted on a top-hat rail in the meter or distribution box, requires a 240V connection … Read more
In order to check whether our house was suitable for a heat pump, I needed to know the preheating temperature and set it so that it did not exceed 40°C. I already have an ESP with a 4-channel relay board in the boiler room and had experience with the Dallas temperature sensor. So I connected … Read more
