Hi!
No, not in any way.
Both devices are radio receivers, so to speak, which wait for transmissions from the surrounding sensors and display or process this.
But this also means that both GW2000 and HP25xxC see the same sensors and should therefore display the same values.
The only exception is the T/H/P sensor WH32B. This is currently not used by the GW2000. For indoor temperature and humidity as well as air pressure you will have different values.
There is no range extension as with a mesh network - each console is absolutely self-sufficient.
