HassOS deconz addon missing refresh of sensors

A bit late, but for anyone else who stumbles onto this thread I had this same problem and was able to solve it by creating a REST sensor that gets its values directly from deCONZ. See the solution here.

Turns out the last_changed value reported by deCONZ to HA is not the same value as reported in Phoscon, but the correct value is available via the REST API.
