Connection unstable after update

[niekveldhuizen]

Hi,

I have been a ESPAltherma user for as long as I have my new house with the heatpump with no issues. I needed some new variables to be available in my Home assistant so i needed to update the config. Now it look super unstable in the conneciton as you can see in the image

The wifi AP is right next to it. And nothing has changes other that 5 more variables
