So I had the Kaifa smart meter with domestic economy tariff installed 3 weeks ago. Now my water immersiand storage heaters only switch on between 12:30 and 1:30 am resulting in no hot water or heating. Engineer requested Ecaul and Alcs configuration from the remote team but there has been no change. Why does my meter ping off at 1am and overnight heating appliances stop working?Â
Smart meter on for 30 min during off peak?

ECAUL stands for "Control Auxiliary Load" and is a process used to configure the fifth terminal (also known as the auxiliary or control terminal) on a smart meter. This process allows you to set up an on/off schedule for this terminal, which can be used to control devices like electric heating.Â

If your heating isn’t switching on as expected (or at the times expected) following a SMETS2 meter install, it might be due to an issue with this ECAUL configuration process, in which case we may be able to fix things remotely. Reach out to our Support Team to report these issues.

Hi ​
Sounds like you may want to request the ECAUL/ALCS be reconfigured again - the settings may not have pulled down properly.
Other than that, did you have any other timers that might be interfering by any chance?
