Today I upgraded Home Assistant to the latest version 0.96.5.

• I adjusted a few things that deteriorated in the meantime. Now the history and recorder tabs are working again.
• I'm using the opentherm_gw component again instead of my own OTGW bridge. This allows me to use the climate thermostat component again.
• I set up OwnTracks with the Private HTTP webhooks instead of the MQTT bridge. The webhooks have as a positive point that these don't need an extra certificate to keep it secure. It will just use the certificate that I use with Home Assistant.
