Tesla template fails with "TypeError: 'float' object is not iterable"

[kodek]

The recommended template picks min/max values as follows:

{{ states('sensor.powerwall_site_now') | float | max(0) | round(1) }}

This leads to a startup error. max() expects an Iterable, and it's receiving a single float value.

I can confirm that the following works:

{{ [ (states('sensor.powerwall_site_now') | float), 0 ] | max | round(1) }}

This might be related to Home Assistant updating the Jinja dependency in 2022.4, but I actually couldn't confirm the root cause.

If anyone could confirm why this broke, whether my workaround is idiomatic, or if there's a more idiomatic solution, I'd appreciate it!

This issue happened to me too - I think it was a HA update as well. The fix looks good to me, and works. Want to raise a PR to fix the example, or shall I?

Hello, I've had the same issue and I solved as suggested in this topic. But after than I have opposite sign of current flow, positive for production and negative for consumption. Example: my Powerwall2 is feeding house with 1kw of power, the card shows that:

• House consumption is -1kW,
• Battery consumption is 1kW,
• Flow goes from house to battery

Before updating Hassio, negative values were find only on battery during the charge phase and on grid when solar current was more than enough.

My sensor configuration is:
