I have a Baxi boiler which used to work with my hive but since a boiler service last year it no longer works with the hive. There is a “grassin” timer pre installed in the system but when I first installed the hive it worked perfectly. I have read potentially it’s because the boiler has been put on a program but I have since reset the boiler to clear all pre existing programs yet the boiler still no longer works with the hive. Any suggestion appreciated
