I would like to calculate the doubling rate of the COVID-19 data.
The formula is: ln(2) / ln(1 - (n_today-n_yesterday) / n_yesterday)
ln means the mathematical function natural logarithm.

Questions:
Is there a way to use the yesterdays value of a sensor?
How to calculate a natural logarithm?

Any other ideas to get value from Covid data?

Hello,

I am completely new to Home Assistant. So to start off this my goal is to have Home Assistant Dim the two lights in my living room when I play media on my Vizio TV. Which I tend to use SmartCast were it uses the plex app to play my media.

Currently the lights that I have are the walmart Merkury, which with Tuya. I do have them added to Home Assistant and can turn the lights on and off via the Home Assistant dashboard.

I’ve created an automation script, and scene script. I’ve check that the automation works by forcing it to execute and triggering the scene, which my livingroom lights do dim and go back to normal, so that portion works. The issue I think is that plex, or smartcast is not triggering the automation. Below are my configs.

I have figured out the ‘magic’ required to fix the above reference problems between HA and the echo devices.

The fix I have found is to do the following:

remove all devices in the echo device list.
deregister all of the echo devices, and add one of them back.
scan for devices again, and the duplicates will go away!

I tore out my hair trying to figure out why it was goofin with me for a couple days!

All,

I have this modified script (See below) in my python_script folder and it works fine when run from SSH console. Now I want to retrieve the data from my district theater once a day so I need to schedule it. Tried/reviewed online very quickly with Node-RED, Crontab, Python-script, Custom Components, AppDaemon but was not successful yet.

Hoped for simply doing a automation calling the python-script once a day but due to imports and limited functionality on that side can’t get this to work. Crontab no option as this is not persistent and running in the SSH console container probably. Node-red and Custom components were still too complex for me, need to learn a bit more by trial and error.

Any advise? Thanks!

I have a mix of automatically created automations and ‘hand made’.
At some point in the later revisions of HA, some of them stopped appearing in alphabetical order.
an example:

I’m not sure, but it seems to be happening if I rename the automation.
This makes it rather complicated to find the automations.
So why does this happen, and how do I fix it?

I’ve started moving quite a few of them to node-red, so the problem gets less and less, but it’s still really odd?

• So I’m running NGINX and a VPN server , on my cloud VPS,
• VPN server IP on the VPN is 10.19.49.1.
• Nginx redirects certain subdomain traffic to my VPN clients.
• One of the VPN clients is running HA.
• Client IP on the VPN is 10.19.49.2.
• On the HA instance , how do I block incoming traffic originating from a specific public IP because my VPN client is receiving all traffic from the VPN server and thus will only “see” my VPN server IP.

Whats happening currently is that on the VPN client running HA I added an iptables rule to drop IP 1.2.3.4 to the INPUT chain (default filter table) .

iptables -A INPUT -s 1.2.3.4 -j DROP

However, I also added logging to INPUT chain and every incoming packet SRC was my VPN server 10.19.49.1 which is correct - but the “originating” IP was 1.2.3.4 which accessed my subdomain , went to my VPS, reverse proxied to my VPN client via my VPN server. All correct, but as SRC on my VPN client incoming packet is always 10.19.49.1 then traffic from 1.2.3.4 is not getting dropped.

This will be easy for a networking guru , but I am at the extent of my knowledge now and stuck.

I built some scenes using the editor but I’m finding that when I execute the scenes the brightness of the light stays at 100% even though the brightness slider is at 5% (the value in the scene). The values are al correct in the generated YAML.

There seems to be a disconnect between the slider (and the value set in the scene) and what actually happens when the scene is set.

Not sure how to narrow down whether this is an HA issue or an issue with MQTT or Tasmota. Any suggestions?

Has anyone tried it yet? Nothing on the integration page and nothing in the forum regarding this new version. I have barely been able to find it.

There also seems to be a Yeelight version of the switch for smart bulbs (it doesn’t seem to be smart at all). Any hints on what does it do exactly?

I just wanna replace my standard three gang switches for Zigbee ones.

Searching for a solution led me to this link but it didn’t provide much info on how to troubleshoot
I tried to ssh into the hass system using the SSH addon but I wasn’t able to find or install the tvservice utility.

What is the proper way to address this issue? I’m a bit familiar with linux but when I ssh I can’t find any installed tools or ways to install tools (apt / yum / etc.)

Hi All,

I played for some time with a great custom button-card creating a card for my ventilation config.
What I noticed was the difference between font sizes Lovelace and button-card use to display entity’s name, for example:

and here’s the config

type: entities
entities:
  - type: custom:button-card
    entity: input_number.ventilation_1st_floor_bathroom_shower_humidity_gradient_threshold
    show_icon: false
  - entity: input_number.ventilation_1st_floor_bathroom_shower_temperature_gradient_threshold

As I wanted to have both standard and custom cards mixed within the Entities card, my goal was to have that “if greater than” string look the same in both input_number and button-card.
In fact, it was a bit bigger - as I use button-card and card-mod anyway, I wanted my custom card to look as close to standard Lovelace card as possible in terms of fonts and colours used (and it’s not limited by input_number, it’s just an example here).
And as it’s custom, it would allow to change it to something different as well (like font size of input_boolean's input field)

To achieve my goal I created several input_text sensor that hold default values for font size and color:

ventilation_ll_auto_settings_font_size:
  initial: '14px'

ventilation_ll_auto_settings_color:
  initial: 'var(--primary-text-color)'

ventilation_ll_auto_settings_input_width:
  initial: '3rem'

and then I use them to create some button-card templates

var_const_states:
  variables:
    invalid_states: ['unknown', 'unavailable']
    
base_row:
  template: var_const_states
  variables:
    margin_left: 0

    current_font_size_entity_id: 'input_text.font_size'
    default_font_size: 'var(--paper-input-container-shared-input-style_-_font-size)'

  styles:
    card:
      # set space between input field and name
      - margin-left: >-
          [[[ return variables.margin_left ]]]
      - margin-right: 3px
    # set standard font size and color
    name:
      - font-size: >-
          [[[
            var val = states[variables.current_font_size_entity_id];
            if (val === null || val.state === null || variables.invalid_states.includes(val.state)) return variables.default_font_size;
            return val.state;
          ]]]

As you can see, it pulls data from input_text and falls back to variables (overcomplicating things?)
And the beauty of using input_boolean here is that it can be accessed from any templateable card (like card-mod)/script and exposed in UI so one can change parameters on the fly/call set_value from an automation and voila, your card picks up changes immediately (well, at least button-card does).

So if I use that base_row as a template, I get a better result

Currently the step I’m missing is how to initialise that input_texts so they hold current (or default) Lovelace values? I.e instead of setting initial (which will reset them on every HA restart) I’d prefer to pull it from Lovelace.

It might be possible to do so from within button-card, for example, as it allows to execute Javascript code so things like querySelector can be used (I can grab font-size of “html”) but I’m not a web designer and at the moment it looks like it would be difficult to dive into shadow DOM to find that information - happy to be wrong here, please show me how!

tl/dr is there any way to store attributes’ values Lovelace uses to display its elements in input_text apart from hard coding them? I had an informative discussion with @RomRider about it, but maybe people like @Bram_Kragten, @thomasloven, @iantrich, @petro or anyone else knowledgeable (I believe there are many of them here) can chime in and guide me a little bit?

Thanks for reading.

p.s There is a good source of default values here, which I’ll hard code if there is no other option.

Does anyone know why?

This is not in itself a problem except if you want to create a new file or rename an existing one, because every time the display refreshes with the new or removed db files the file name box you are trying to type in loses focus.

I’m trying to make some automations for a utility meter. I use different input_numers to keep values persistent and at certain times I want to reset the different input_numbers. My idea was to use an automation that triggers once a day and then use templating to reset certain values once a day, once a month and once a year. But my automation doesn’t work, the values doesn’t reset.

This is the code for my automation:

- alias: Energy - Reset input_numbers 
  initial_state: on
  trigger:
    platform: time
    at: "0:00:03"
  action:
    - service: input_number.set_value
      data_template:
        entity_id: >-
          {% if now().month == 1 and now().day == 1 %}
            - input_number.energy_daily
            - input_number.energy_monthly
            - input_number.energy_yearly
          {% elif now().day == 1 %}
            - input_number.energy_daily
            - input_number.energy_monthly
          {% else %}
            - input_number.energy_daily
          {% endif %}
        value: '0'

Can someone please tell me what is wrong with my code?

I need Zigbee to integrate with a lock (simple lock/unlock commands). What would the simplest and cheapest way of doing this be with Hass and a Pi, while still reliable?
