Heating Panel Conflict between Gateway and Slave

[Dunkigrease 0]

HC2 Software master gateway and HC Lite slave both at version 4.630

 

TKBHome electric underfloor heating controllers which interface fine, although there is no device template.

 

I have 8 controllers on the master gateway and 3 on the slave, running for several years without problem.

 

Each controller is established as a discrete zone with its own scheduler. 

 

I realised regarding the three on the slave that I wanted them all to go on or off at the same time so I thought why not put them in a single group.

 

I created a group on the Master for the three controllers on the HCLite slave., but I left the schedulers on the HC lite as they were.

 

Now the three controllers on the slave keep attempting to switch on  every few minutes.  I'm not sure exactly how frequently it happens but I have just noticed it happening.

 

Could this be due to the group scheduler set up on the master conflicting with the individual schedulers on the HC Lite?  or is it something else?

 

Thanks in advance as always.
