Defaulting cleared all previous programming as well as reset all counters and outputs in order to give us a fresh start. When ElkRP2 is connected to the M1 all other communications are suspended which is why Home Assistant/Homeseer did not see the change in the counter value. It is not uncommon to see the Retries to increment over time however if the M1 starts displaying or logging Missing Expansion Module issues then we’d need to check:
- Data Bus configuration — no more than two home runs or use of the M1DBH or the M1DBHR to manage the data bus
- Proper termination of the M1 Data Bus — see page 12 -13 of the M1 Installation Manual which describes the 3 methods to wire the bus and proper termination
- Proper voltage at each bus device making sure it is between 12-14 VDC
