Hi,
Many thanks for your help previously with my RS485 issue. Issue is now resolved per your advice and Gary Morgan. System working well. I am planing going to Economy 10 electricity tariff.  This gives 10 hours of cheaper electricity during the day - there are 3 periods . However the meter is timed with  UTC time and does not change with Summer Time changes.
Via MOD BUS TCP interface with the Victron solar battery inverter and charger I want to control when the battery is charged (if not enough solar) so that the Grid charges the battery during the cheaper periods and then discharges during the more expensive time periods.
I have tested the Comfort MODBUS TCP interface with the Victron unit and this works.
The issue is how to manage UTC. I do not want switch off the time synching via ETH03 as this set all my time programs for Heatmiser and DHW etc.
How would you go about setting up time programs in this case?
The Time period below are UTC.
    Three off-peak hours in the afternoon (e.g. 1pm – 4pm)Two in the evening (e.g. 8pm – 10pm)Five overnight (e.g. midnight – 5am)
Best wishes
Mark
