• Toggle LCDlock using o and > buttons at powerup
• Added help texts to webserver screen when hovering with mouse
• OCPP: Enable backlight when presenting RFID tag
• OCPP: if UID bytes 5 and later are zero, assume 4 byte UID
• Invert power measurement when receiving currents for Inverted Eastron, and display values correctly, thx to PimDoos
• Improve error handling in setTimeZone; check multiple websites to determine location
• Fix Stop charging if Capacity is reached and timer is not set
• Fix slave not receiving modbus info
• Fix disconnect MQTT when changing its params
• Fixed bug, now we store Daily Repeat correctly in memory
• Fix RFID EnableOne option: write the 16bits CardOffset value to 16bit NVS key

Release v3.7.2

This release adds a menu-option to the LCD-screen when a Sensorbox-2 with old firmware is detected; the menu option will enable you to upgrade your Sensorbox-2 firmware without having to disconnect it, and without having to connect to the USB-C connector. The “Setup” option will provide you with a portal (old fashioned SmartEVSE style) as an access point to your smartphone.

For details on upgrading your Sensorbox-2 firmware see https://github.com/dingo35/Sensorbox-2/tree/v2.1.0?tab=readme-ov-file#upgrading-firmware

Release v3.7.1

This is a bugfix release:

• fix firmware upload links on /update webserver page
• correctly initialize RFIDlist on 1st powerup
• make reboot also respond to GET request
• fix HomeAssistant MQTT discovery error message for OCPP topics

Release v3.7.0

NOTE: don't use this version, the links in the update screen are pointing to the wrong firmware, so this firmware will run fine until you update from it.

Changes:

• added OCPP support
• LED colored push button now fully accessible by APIs, thx DanInden
• support to activate Sensorbox-2 wifi update over modbus
• support par.14a of Energy Industry Act, where an energy provider provides a relay that reduces the power consumption to 4.2kW
• support of using LED colored push button as CheapTariffIndicator
• fix bug in EnableC2 = AUTO: Reset Auto 3F>1F switch in StateA
• enable RFID 7 byte reader support

Release v3.6.10

Bugfix release with the following bugfixes:

• Preferences from the LCD menu are now saved correctly.
• In Solar mode, when StopTimer Disabled, the EVSE now continues to charge indefinitely, as per documentation.
• When Mains is lower then Max, we now allow charging up to Max when Mains is not exceeded (e.g. when solar power is added to the house grid).
• The MQTT topic that was named EVEVMeterEnergyCharged incorrectly is now named back to EVEnergyCharged.

Known bugs: spurious malformed MQTT packets are generated, which cause the MQTT broker to disconnect and immediately reconnect. This problem is rarely noticed, it has been there since v3.5.1 .

Release v3.6.9

Yet another bugfix release; fixed two bugs that disturbed the limiting of charging to MaxMains.

It is highly recommended to upgrade to this release to protect your main fuses!

Known bugs: spurious malformed MQTT packets are generated, which cause the MQTT broker to disconnect and immediately reconnect. This problem is rarely noticed, it has been there since v3.5.1 .

Release v3.6.8

This is a bugfix release, where an annoying bug that disturbs modbus traffic is fixed.

Known bugs: spurious malformed MQTT packets are generated, which cause the MQTT broker to disconnect and immediately reconnect. This problem is rarely noticed, it has been there since v3.5.1 .

Release v3.6.7

Changes:

• eliminate strange rebooting behaviour when changing MQTT password
• disabling MQTT by emptying MQTT host field works now
• Fix Power measurement for modbus meters
• Remove unused Calibration option from code
• fix Normal mode charging bug introduced in 15aec8c
• prevent slave from waking up from OFF mode when Masters' solarstoptimer starts to count
• esphome: fix API return code 411, see issue #109
• OCPP: Allow using SmartEVSE local RFID storage with OCPP
• remove OCPP from LCD menu since it is configured on the webserver
• platformio.ini: update OCPP commit hashes

Release v3.6.6

Changes:

• We fixed the wifi reconnection problems some people (especially with low SNR on their wifi reception) experienced
• We are introducing the OCPP code; it is still in alpha phase, but if you can compile it yourself you can experiment with it, by adding "-e ocpp" to your compile command line. Then the ocpp section of platformio.ini will be used.
• We re-introduced some "ugly glitches" of the LCD screen that were removed in v3.6.5; turns out the screen has to be re-initialized when contactors are switched, since in some situations the switching causes a disturbed LCD screen
• We added to the docs a long time but unknown feature: if you pres < and > button at the same time, the LCD screen will be refreshed
• We improved the reading of the RFID reader by using a better library
• We renamed MaxSumMains to Capacity (and Sum Stop to Cap Stop), since it is the Capacity Rate Limiting laws that we are trying to serve here

Known bugs:

• Current RFID reader only reads 6 identifying bytes off of your NFC tag, and it turns out there are OCPP tags out there that use 7 bytes. Please be aware of this if you are experimenting with OCPP.
• In Master/Slave configuration, in Solar Mode, if the Master starts the solar stop timer, and a Slave is in OFF mode, the Slave will wake up into Solar mode too.

Release v3.6.5

Note: this release replaces v3.6.4; some users reported problems with reconnecting wifi if the connection got lost.

Changes:

• We improved the wifi reconnect code
• We got rid of the rather large wifimanager library; you now have to configure your wifi through the ESPTouch app; as a backup we built a backup procedure over the serial interface
• Added Sinotimer DTS6619 kWh meter, thx to kwertie01
• Fixed bug where MaxCircuit was not always obeyed correctly, and sometimes obeyed when it wasn’t supposed to
• Introduced MaxSumMainsTimer (Sum Stop in the LCD screen) so Capacity Rate Limiting can be managed through a timer, just like the SolarStopTimer
• Removed some ugly glitches from the LCD screen
• Fixed some smaller bugs, e.g. calculation of Baseload_EV when no EVMeter connected.
