1.5.1 - Amp woes

Changes:

• Max Amps control is no longer disabled during an active charging session

Last release I disabled amp control during charging because my Telestar EC311S6 errors when lowering max amps.
But it has been brought to my attention (#7) that some devices like the Besen B20 do support this.

I've globally re-enabled this with a warning in the README, I will look into disabling this on a per-device basis in the future.

1.5.0 - Phase Shift

Adds:

• Diagnostic sensors for per-phase voltage and current (L1/L2/L3), disabled by default
• Session Max Current sensor showing the confirmed amperage limit of the current/reserved session (Thanks @MarijnS95)
• Diagnostic sensor for device clock offset (shows the active firmware clock workaround value)

Changes:

• Max Amps control moved to the Configuration section of the device page
• Max Amps is now unavailable (greyed out) during an active charging session

Fixes:

• Start charging errors now surface properly in the HA UI instead of showing a generic message
• Reservations more than 24 hours in the future are now rejected early with a clear error
• In actions max_amps above the device hardware limit now raises an error; values above the configured max are silently clamped
• In actions start_datetime without a timezone now assumes local time instead of failing
• Device clock offset is now correctly reset to 0 when the device clock recovers to within 24 hours of local time

1.4.0 - Sessionify

Adds:

• Information about the current charging session: Start time, Duration and KWh. (Thanks @MarijnS95)

Fixes:

• Typing issues when you haven't used reservations (Thanks @MarijnS95)
• Start charging button not working

1.3.1 - Time and Time again

Fixes:

• Start/Stop button logic. Should be available more often and work even when charging is completed.
• More time issues!

Starting January 2026 I started seeing weird time discrepancies where the device thought it was 10th of feb internally while sending and showing it was actually 10th of jan.
This release implements time syncing to the device and adds a workaround if the received time while setting is massively out of spec.

1.2.3 - Little Fixes

Fixes:

• Date received is apparently in Shanghai TZ
• Start charging not working

1.2.0 - Actions

Adds:

• Custom Actions!
  You can now schedule a single charging settings the the action evsemaster.start_charging
• Reservation Info
  You can now see the next time a start is schedule to start with the max duration

Fixes:

• Setting Nicknames should now be fixed.

V1.1.0 - More Configs

• Text sensor to set nickname
• Number sensor to set max amps
• Translate Plug/Current states

V1 - First Proper Release 🎉

Currently Supported:

• Some Device status info
• Current charging speed
• Total KWh
• Start/stop charging
