I just noticed Home Assistant supports Indieauth to get access tokens. That's great! p83.nl/p/1611

EMS Gateway connected with Home Assistant
In our new home we don't have an OpenTherm compatible boiler. This is no big problem, but I do need a different device to read the information from the boiler. Our Nefit boiler uses a different protocol, called EMS.
The boiler we have, has a special "status" port where you can read the information from the boiler. BBQKees created a small device that can do this. This device has support for Home Assistant through MQTT.
When the device is connected, you can adjust the temperature from Home Assistant using the Thermostat widget on the dashboard. This is really easy to setup and use.
Home Assistant contains a component to control an OpenTherm Gateway, but it seemed not very stable. The gateway sometimes has timeouts and these also happen in Home Assistant. The problem was that HA stopped in the middle of the night and became unresponsive. To resolve this problem I have created a go program that copies temperatures from and to the gateway. This is a lot more stable as the timeouts don't hinder the processing. With a input_select component and a few automations I now have a more stable and responsive heating control system.
