Thanks for the kind comment @AJStubbsy, while I’m on my break from the workplace over the coming holidays, I’ll look into what doing that will look like.

Thank you for your respond,
I think i have found it:
value_template: '{{ now().day == 08 }}'
changed the day == to 8, without the 0. and then no errors anymore… Don’t know why 08 gave the error.
one other question, is it possible to get a notification when the cycle restarts, so for me on the 8 day of the month, and the automation did his reset, than send a notification.
Or maybe also when you have 5 pages left for the month or someting?
Something like this, but i do not know how to format it correctly:

Probably. Most things are possible, but it’s a question of how, and of time. What do you mean by, ‘a notification?’
It’s very likely that a notification would be implemented in a separate automation.
For an email, there is the additional prerequisite of a working connection to an SMTP server, and what choice of wording to use.
At this time I don’t know what a notification to the Home Assitant App would mean, in terms of what to do.
Ow true, sorry i forgot to explain better. (did not even know about email notifications haha)
Example, i found a shutdown notification example:
trigger:
platform: homeassistant
event: shutdown
action:
- service: notify.mobile_app_galaxy_s8_rick_sm_g955f
data:
message: Home Assistant wordt afgesloten
This uses the notify to send a message to my phones home assistant app.
I am looking for something like this when for example my Total Pages Left hits the 10.
Or when the monthly cycle resets.
I thought it would maybe be possible to include it in the existing printer automatisation, or is it better to create a sepperate one?
This is a great contribution to HA and the community. I’ll have to wait for the add-on unfortunately, as I don’t use packages! 
I’m only joking as I know it would be difficult to design for an version of HA you don’t run but this might spark the interest of someone who uses HAOS to get involved, so thank you very much

The package is great, thanks 
By default, sensor.date doesn’t exist therefore Allowance Days Remaining was showing up for me as 19077… Adding this to configuration.yaml fixed it for me…
sensor:
- platform: time_date
display_options:

As of the new HA versions, some templates need a default value.
It is giving some new errors now:

I don’t know what the recommended values are (I haven’t got this configured in the same way as you) but you can add a default by putting it in brackets after the int i.e. |int(0)
You might as well give 0 a try, as it’s just to get past the initial setup and then it’s actual value will be known.
Thanks for the reply!
I tried with a few values, but still errors. Do i neet to put (0) after EVERY “int”? even in the middle of the line of code?
Example
'{{ states('sensor.hp_officejet_8022_pages_allowance_remaining')|int**(0)** + states('sensor.hp_officejet_8022_pages_rollover_remaining')|int**(0)** }}'
Sorry it’s probably quite late to reply to this, hopefully you got it sorted. You should set a default value for any of the states that are going to generate the error. It’s only a temporary state, so no harm.
{{ states('sensor.hp_officejet_8022_pages_allowance_remaining')|int(0) + states('sensor.hp_officejet_8022_pages_rollover_remaining')|int(0) }}
Should stop the error.
For one of your errors, I vaguely remember some issue about as_timestamp. Might be worth having a look through the forums to see if there is a better way to write that template.

Hi there,
I’ve been using this for a while and have recently been experiencing some issues (can’t pinpoint when this happened, unfortunately).
It seems that the issues are connected to the fact that I’m not able to get the total pages printed from the xml anymore.
The following sensor returns “unknown”
- platform: scrape
resource: http://IP/DevMgmt/ProductUsageDyn.xml
name: hp_officejet8720_total_pages_printed_xml
select: 'dd\:TotalImpressions[PEID="5082"]'
value_template: >-
{{ value|int(-1) }}
This is the value I’m trying to get:
Meanwhile, hp_officejet8720_total_pages_printed (which is basically the backup of the xml value) is stuck at a number about 20 pages ago.
Did I miss something?
I’ve already tried the following options for select:
'dd:TotalImpressions[PEID="5082"]''dd:TotalImpressions PEID="5082"''dd\:TotalImpressions PEID="5082"'
Would be amazing if anybody had an idea why I’m getting the unknown for this

The scrape sensor has been updated. Change it to this:
scrape:
- resource: http://IP/DevMgmt/ProductUsageDyn.xml
sensor:
- name: "hp_officejet8720_total_pages_printed_xml"
select: 'dd\:TotalImpressions[PEID="5082"]'
value_template: >-
{% if value == "" %}
0
{% else %}
{{ value }}
{% endif %}

You could also follow the github instructions and use the scrape sensor UI integration but you don’t have to.
