WARP Energy Manager: Fix phase switch for firmware v2.0

[poohnet]

Mit WEM Firmware 2.0 wurden die MQTT-Topics "/energy_manager/state" und "/energy_manager/external_control_update" in "/power_manager/state" bzw. "/power_manager/external_control_update" umbenannt.

Can you please add a comment to the template that fw2 is required?

[poohnet]

Done :-)

I cannot see "/power_manager/external_control_update" in the MQTTExplorer - only "/power_manager/external_control". Might explain why I can't start the charging anymore through EVCC since the last WEM firmware upgrade

@andreas-bulling : Same for me here. There is no charging through EVCC possible since last EVCC Update. I updated the Energy Manager to 2.01 but no possibility for charging.
What can I do?

[andreas-bulling]

"Good" to hear that I am not the only one. I started questioning my overall setup (although I didn't change anything else...)

[DerBauch78]

Same for me. The problem with me is....I am a (DAU) user. Once I installed and configured EVCC (5 month ago) everything worked well and I have the tendency to "set and forget". And because I am a DAU User I updated the last EVCC (yeah I know...never change a running system.) So I have to get my brain in the Setup again and have to understand again what I have done a few month ago.

For me the problem did not start with the latest EVCC version but the latest EM and Charger firmware. The beta version before Christmas was still working, the latest ones don't. Also upgrading to evcc 0.124.0 didn't fix the problem

[DerBauch78]

the funny thing is... I don't even have a car. It's my wife that wants to charge her car to go to work.... and if the implemented routine stops working => that's not good for anybody ;-)
Back to the topic: I have the same impression that EVCC can't tell the EM to update the Phase switching, perhaps because of the faulty MQTT topic.

[DerBauch78]

I tried to sniff around in the MQTT Messages...same for me; I Can't find a topic called "/energy_manager/external_control_update", only a"/energy_manager/external_control"

[DerBauch78]

Ok, ich habe deinen Faden im Tinkerforge Forum gefunden und Wechsel mal rüber ;-)

[andreas-bulling]

I just wanted to point you to it :)

We've improved this on our end: The WEM will recover the last phase setting after a reboot with the soon to be released firmware 2.0.2.

Great support @rtrbt, much appreciated!
