Besides what Tom says, it looks like your “sensor.modbus*” do not exist when the templates are evaluated.

Too few information for a fix.

vinceg0267 · June 25, 2023, 9:04am

What information is needed?

koying · June 25, 2023, 10:13am

Whatever you think is relevant.

We don’t even enough info to tell you where to start. All we know is that a sensor.modbus_zcs_energia_generata_totale (and co.) is not existing when you try to evaluate a template somewhere.

Apparently, it is for availability ( for attribute '_attr_available' ), in which case you should check if sensor.modbus_zcs_energia_generata_totale is not null first.

What I can say is that this error only occurs when restarting the HA, after which the sensors seem to do their job.
These are the original sensors:

You likely already changed the template according to Tom’s recommendation.
I’m pretty convinced you won’t have the message at restart, now, but to be sure;

        availability: "{{ states('sensor.modbus_zcs_energia_generata_totale') is not None and states('sensor.modbus_zcs_energia_generata_totale') | float(0) > states.input_number.filtro_produzione.state | float(0) }}"

aceindy · June 25, 2023, 11:00am

It is probably because the secondary sensor is created before the main sensor…
The fault will resolve itself (apparently) when the main sensor loaded.

Solution as Koying said (or change the order of loading the sensors)

PS Good to hear you got it to work

vinceg0267 · June 25, 2023, 11:01am

Yes I had made the change but when I restarted I always got the message.
I’ve now made your change and when I check configuration HA notify me this message.

Invalid config for [template]: invalid template (TemplateAssertionError: No test named 'None'.) for dictionary value @ data['sensor'][14]['availability'].

This is a follow up on another post

vinceg0267 · June 25, 2023, 11:18am

No, in the modbus.yaml file the order of the sensors is correct. First the main sensors are created.

vinceg0267 · June 25, 2023, 11:19am

But they are different problems

koying · June 25, 2023, 3:58pm

Man, it’s literarily the first google result:
no test named ‘None’ · Issue #520 · pallets/jinja · GitHub

Use lowercase none (and please help yourself a bit).

vinceg0267 · June 25, 2023, 4:15pm

Man don’t be angry please, I’m sorry, I’m newbie and I don’t know English well. I am very grateful for your help.
