maybe it will be useful for others to know that the time is stored in 2 bytes, but when read, the hours are in the first byte and the minutes are in the second (hours=value/256; minutes=mod(value/256); 6412 => 12:25) and vice versa when writing (value = hours*256+minutes; 12:25 => 3097)!
Hi, It has been a while but I’m still using this code in my HA setup. Since the latest update of HA however I get notifications (several, 12 to be exact), see the atached screenshot. What as happened?
I’m wondering why more people aren’t using it - no reliance at all on the cloud servers and you can poll as quickly as you like. I’ve been using for over 18 months with no issues at all 
I’ve been working on some automations and dashboards to control the inverter, some of you may find them useful. I’ve wrapped @kamilb work into a package to make things simple for adding to your configuration.yaml.
I’d appreciate any feed back/criticism.
A basic summary of what the automations/dashboard allow you to do:
- Change basic settings/modes on the inverter
- Control when your Zappi is allowed to get an octopus dispatch
- Export the battery daily/maually
- Prevent house battery discharging into the EV if the CT clamp can see the Zappi load
- Send notifications.
- Participate in Octoplus Saving Sessions/Free Electric (not tested)
Your Zappi must be the registered device with octopus (not your EV)
