Mcohome appareantly released a different id-version of the same product.
Tested it with the new product type and id, and used the original "mcohome/mhs412.xml"
as the lifeline switch is still present in this version.
It now performs perfectly.
Product type="4121" id="1302"
No idea as for naming convention but i named it version B as its a black one + info on the box says "MH-S412-EU B" (switch just says MH-S412-EU on the back)
