Feedback zum Twiz o´meter

No, the total driven km.

Please forget my last question. Problem solved.

I'm using ToM since a week now and thanks to further support, out of the forum, too, I managed to reduce Charging Power depending on available power (PV radiation).

Attached screenshot shows the different energy flow in our home:
- yellow: PV generation (roof)
- green: grid feed-in
- red house consumption
- orange : grid consumption (not suffizient generation available)

Yesterday we got a cloudy afternoon, while needing to charge the Twizy.

As you can see, shortly after 2 pm the Twizy got connected and the Charging Power could be manly kept below the yellow line. Every 12 min the setting was over writen by the BMS and charging was done for approx. 1,5 min with 2 kVA. Twizy got disconnected at approx. 3:25 pm

The graph on the bottom nicely shows the communicated Charge Level 1 to 5.

Pretty cool



Seit einer Woche nutze ich jetzt das ToM und konnte, auch mit Hilfe aus dem Forum, jetzt umsetzen, daß die Ladeleistung immer unter der verfügbaren "freien Erzeugungsleistung" bleibt.

Beigefügter Graph zeigt sehr schön das gestrige Verhalten, als es nortwendig war, den Twizy zu laden, trotz geringer Einstrahlung.

Kurz nach 2 Uhr wurde eingesteckt und die Ladeleistung (rot) blieb sehr schön unter der gelben Kurve. Regelmäßig hat das Twizy BMS "gestört" und die volle Ladeleistung eingestellt (ist halt so).

Der untere Graph zeigt sehr schön die zugehörigen Ladelevel vom ToM 1 bis 5.

Einfach super !

Hi Eckhard,
thanks for sharing your feedback.
I'm happy you used the new features implemented with last fw 1.6.
So, you made an adaptive (not fixed) control of the charging level depending on available PV power? Am I right?

yes

Waiting for my twyz o’meter to arrive, i was wondering if it would be possible to display the current state of the 12V batterie ? If not, maybe a future option, since 12V batterie state is cause of so many problems it seems

You can display the service battery voltage.

Ok! Thanks

Could it be, that ToM "likes" only to display abs.BattTemp.values ?

Today when started to drive outside temp was well below zero, and the DISPLAY showed 4°C.

Slowly the battery temperature (display) went to 3°C, 2°C, finally 0°C.

Using mqtt data are fine, with negative sign

Könnte es sein, daß das Display nur positive Batterietemperaturen anzeigt, auch wenn sie definitv negativ sein muß ?

You are right.
Display doesn't show the sign. It's a limit of my first writing of the code. I realized it during the "Spring porting" of my project, where there are more values with negative sign.
At the moment, the easiest way to solve is to add a different icon for negative temperature (like, for example for A or kW icon during recuperation).
Showing sign would need an huge intervention on the code (for the high number of parts of code to be modified) and the regeneration of the font used for little number, to add the sign symbol (a complex task for me).
Is that solution acceptable?

Should be definitely fine, keep it simple

Between you and me (in exchange): Don't forget implementing V2H DC-Bidi capabilities into your Spring Project [no just kidding ]

Any idea about the min limit for temperature and other value?
Motor/battery temp -20° ?
Ah -100 ?
kW -32 ?

Motor/battery temp: -20°C - should be fine/sufficient

neg Ah, I would say no, just: 0 Ah

here max possible reku: -?? kW
just my thoughts

Moin Zusammen,

ich möchte hier mal ein riesen Lob los werden…

Es macht so viel Spaß mit Fabio zu arbeiten !
Er ist so mega engagiert – das findet man leider nicht mehr so oft. Ich hoffe, das bewahrt er sich und wird nicht mal von jemanden ausgenutzt.
Stets zuvorkommend und fachlich auf einem sehr hohen Niveau.

Ich hatte lediglich nur eine kleine Frage zum Schaltausgang vom ToM und zack habe ich eine neue Firmware im Posteingang. Hätte ich zwar nicht unbedingt für den Anwendungsfall gebracht, aber damit wird es eindeutiger. Das ist echt unbeschreiblich…

@Fabio: tausend Dank nochmal

LG Tom

Hi everyone,

I would like to give you a huge compliment...

It's so much fun to work with Fabio!
He is so dedicated - unfortunately you don't find that very often anymore. I hope he keeps that and doesn't let anyone take advantage of him.
Always courteous and professional at a very high level.

I just had a small question about the switching output of the ToM and I had a new firmware in my inbox. I wouldn't necessarily have used it for this application, but it makes it clearer. This is really indescribable...

@Fabio: a thousand thanks again

LG Tom

Unfortunately not all ToM owners share their experience, but when this happens it make me happy!
