Dangerous: EVSE defaults to 32A after reboot!

[HA-TB303]

I have noticed the SimpleEVSE-Wifi defaults to 32A after a reboot even though I have set the MAX CURRENT in settings to 20A. THe webUI shows 32A and that settings is actually active. This leads to a potential dangerous situation as the car will pull 32A if activated after a power failure.

I have set the ESP to

• Wifi client
• Meter hardware to SO
• NO RFID
• MAX Current: 20A
• NO button
• NTP server set to pool.ntp.org
• time zone set to GMT+1 Brussels

EVSE Registers 1000: Configured Current 16 1001: Actual Current 16 1002: Vehicle Status 3 1003: PP-Limit 20 1004: Turn off bit 0 1005: Firmware Version 9 1006: EVSE Status 2 2000: Current after boot 32 2001: Modbus Status 1 2002: Min. Current Value 5 2003: Analog Input Config 1 2004: Amps after boot (evse-button) 0 2005: Register 2005 8192 2006: Current Sharing Mode 0 2007: PP-Detection 0

Current after boot is set to 32A, but I have no clue as how to set that to 20A.

In depended of this situation. My understanding is that the resistance PP-PE will overrule physical the limit

If you have bluetooth available try the APP from the developer to change the register. http://evracing.cz/evse/evse-wallbox/app_20171118.apk

Hi michel72,

sorry for the late response. You don't need the HC06 BT Interface to do that. In the WebUI of SimpleEVSE-WiFi you can click the 'pencil' on top of the table 'EVSE Registers' in Settings page (see attached screenshots). Click that and than you can change register 2000 (Current after boot) to 20.

Ahh thanks. This was obviously not a bug :)
