I have been ignoring updates for a while, just being busy. After updating HA recently my previously working lovelace config stopped rendering thermostats in vertical-stack:
Hi @petro, thanks for reply. Yes, I want a vertical stack of termostats because then it renders (rendered I should say) them in a nice compact way, which is a bit different from an individual thermostat look.
