EVSE-WiFi Board

I've read a lot, but the information is scattered. This is NOT about the WIFI module, but about the EVSE-WB/DIN controller. I've managed to fix the "problem". In the past, they sent me firmware with Modbus enabled by default. The new rev18 firmware has Modbus disabled by default (as in man...

Problem fixed, I needed to activate Modbus via button 5x push in the first 3 seconds.

This procedure should be documented step by step.

Back to rev 15 - same problem So NOW I know why is not working. I've asked for Pickit FW, but is Bluetooth FW, for some reason. I need something like evse-wb_modbus_ rs485 _rev15_20200323_unified_boot3.hex Now I need to find a very old Android 6 phone ;( Does anyone have a Pickit FW? for some reason...

I've tried to upgrade one Simple EVSE WB (not DIN) with Pickit 4 I've used the file simple-evse1.1_modbus_rev18.X.production.unified.hex All went fine (see attached log), BUT using the same SimpleEVSE WIFI v1.1.1 module I get now Modbus error in the interface. I have a feeling that is the wrong FW (...

Inside the link, on the first page, you will see the inside of an OpenWB Duo, on their board. On Youtube you can find a detailed video of OpenWB, with phase switch, but in german. As a linux developer and part owner of a software company, I know something about open/closed source. This is not about ...

Some pictures are from their discussion board :( https://openwb.de/forum/viewtopic.php?t=547 I can understand the rules and I do not push the issue, but this is paranoia. A simple search for the issue on Google Images returns the images, with public access. If I would buy an OpenWB or SmartWB, I hav...

Hmm now I have another dilema. For RCD, is important that you correctly connect the wires IN -> OUT For the B Type we have: IN 1-3-5 OUT 2-4-6 But in the pictures we have a Chint nl210 40a B Type https://chint.co.uk/wp-content/uploads/2018/06/NL210-63.jpg So, the wiring in the OpenWB is showing that...

Is not logic, as Fi-B already include Fi-A capacity!
The problematic current goes backwards.
From evse -> fi-b -> fi-a (rcbo).

First will trip Fi-B

I have Rcbo (this is rcd type a + normal fuse, all in the same package)

Just to be clear
Now I have Rcbo type A -> Rcd Type B -> evse.
If dc fault appear, Type B should trip first.

Hello! In the latest manual , I see some reference for RCD sensor support, but no info on how to connect such a sensor. + Firmware updates 2020-06-25 revision 17: - stricter CP signal check (pilot low decision level, shorted diode) 2020-04-27 revision 16: - added RCD feedback support for EVSE-WBDIN ...
