I’ve already been plugging in data from my Emporia Vue, which reads the meter from Southern California Edison and allows me to query my usage in kW/h from Home Assistant. I now need to calculate cost, which is variable based on what SCE calls TOU (Time Of Use). This essentially means peak hours (typically 4PM - 9PM) have higher rates than off-peak. I broke this problem down into 3 entities to solve: TOU Season TOU Peak TOU Cost I can use Cost as the dynamic entity in our Energy Usage dashboard. This, combined with the kW/h reading, can be used to calculate total energy costs per day. This defines the 3 entities in my sce.yaml. If you’re copying this, plug your peak costs into the last few lines of this snippet: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 template: - sensor: - name: "TOU Season" state: "{{ ['Winter', 'Summer'][now().month >= 6 and now().month < 10] }}" icon: mdi:weather-cloudy-clock - sensor: - name: "TOU Peak" icon: mdi:calendar-clock state: > {% set is_weekend = now().strftime("%w") == 0 or now().strftime("%w") == 6 %} {% if states('sensor.tou_season') == "Summer" %} {% if now().hour >= 16 and now().hour < 21 %} {% if is_weekend %} {{ "Mid-Peak" }} {% else %} {{ "On-Peak" }} {% endif %} {% else %} {{ "Off-Peak" }} {% endif %} {% else %} {% if now().hour >= 16 and now().hour < 21 %} {{ "Mid-Peak" }} {% elif now().hour >= 21 or now().hour < 8 %} {{ "Off-Peak" }} {% else %} {{ "Super Off-Peak" }} {% endif %} {% endif %} - sensor: - name: "TOU Cost" icon: mdi:currency-usd device_class: monetary state: > {% if states('sensor.tou_season') == "Summer" %} {{ {"Off-Peak": 0.15, "On-Peak": 0.41, "Mid-Peak": 0.30}[states('sensor.tou_peak')] }} {% else %} {{ {"Super Off-Peak": 0.15, "Off-Peak": 0.15, "Mid-Peak": 0.38}[states('sensor.tou_peak')] }} {% endif %}
As of Dec 2021, this is now outdated. I am no longer using Dendron, nor nomad to deploy the site. I’ll have a follow up shortly. This expands on the DroneCI -> Nomad pipeline I examined earlier I explained why I use Dendron, today I will show how. The glue that binds Dendron, Quantified Self reports, and Hugo is DroneCI. The CI build runs every night and immediately when a commit is made to the Hugo site. I wrote a custom Pod for exporting notes. It’s similar to the built-in markdown pod, but includes frontmatter and renders a hierarchical structure which makes Hugo happy. The server completes these build steps: Clone the required build repos from Github / Gitea: Hugo site workspace Hugo site theme Dendron workspace and notes Dendron <-> Hugo export pod Nomad config files Once the files are in order, we install dendron-cli and link the hugo-pod in an node container Apply the included patch that skips validation of the pod Run the export pod, creating a well formed /garden/ subdirectory in Hugo’s content folder Build the Hugo site Build the final Docker image with the new public directory Publish the final Docker image Send a redeploy command to Nomad using the config cloned in step 1. Prune old Docker images from our registry Done! Simple, no? 😆 The complexity stems from the sources being so scattered (Dendron, Hugo, Nomad…). Obviously this isn’t practical for casual note writing. But in my head, if it’s worth doing it’s also worth overdoing. This is the full .drone.yml spec: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 kind: pipeline type: docker name: default clone: git: image: plugins/git recursive: true submodule_override: "themes/novela": https://git.quinncasey.com/qcasey/hugo-theme-novela steps: - name: "Clone hugo theme" image: alpine/git commands: - sed -ir 's$:$/$' .gitmodules - sed -ir 's$git@ssh.$https://$g' .gitmodules - git submodule update --recursive --init - name: "Clone Dendron notes and export pod" image: alpine/git commands: - git clone https://git.quinncasey.com/qcasey/hugo-pod.git - git clone https://git.quinncasey.com/qcasey/notes-framework.git notes - cd notes - git clone https://git.quinncasey.com/qcasey/notes.git garden - name: "Export Dendron notes" image: node:current-alpine3.11 commands: - npm install -g @dendronhq/dendron-cli - cd hugo-podand - npm install # Skip validation error "data must NOT have additional properties" - patch node_modules/@dendronhq/pods-core/lib/utils.js < utils.js.patch - npm link - cd ../notes/ - npm link hugo-pod - dendron-cli exportPod --wsRoot ./ --podId hugo --podPkg hugo-pod --podSource custom --config "fname=dendron,vaultName=vault,dest=../content,includeStubs=true" - name: "Build site with hugo" image: klakegg/hugo:ext-alpine commands: - hugo - name: publish image: plugins/docker settings: registry: registry.quinncasey.com repo: registry.quinncasey.com/garden-quinncasey tags: - latest - ${DRONE_BUILD_NUMBER} username: casey password: from_secret: registry_password - name: clone deployment dotfiles image: alpine/git commands: - git clone -b abathur https://git.quinncasey.com/qcasey/dotfiles - name: redeploy nomad image: multani/nomad commands: - nomad run -address=http://192.168.1.196:4646 -var=image_id=${DRONE_BUILD_NUMBER} dotfiles/nomad/webserver/quinncasey.com.nomad - name: prune images image: anoxis/registry-cli:latest commands: - /registry.py -l casey:$PASSWORD -r https://registry.quinncasey.com -i garden-quinncasey --delete --num 10 --keep-tags "stable" "latest" environment: PASSWORD: from_secret: registry_password

Digital Garden I like the idea of writing with the garage door open. I write notes to help myself a year from now. But if I publish an obscure thing that helps someone do something cool, I wouldn’t complain. Our natural fear of being judged leads most people to build, learn, and think privately. But seeking validation should not be the goal of learning in public. ~ Anne-Laure Le Cunff My sites are hosted in my Homelab, these notes are written in Dendron. I publish the site using Hugo. Plain text is wonderful. It allows me to easily find ideas, references, links, personals notes, tasks, thoughts and everything else I want to keep handy. Even short jots and thoughts deserve their space. Being useful for me is the primary use case for this space on the internet. It’s not that I don’t care about you, but this is for me. It’s here so I can record what I think and know and preserve it in time and space. It’s my garden, but I’m happy for you to hang around and eat tomatos with me. https://joelhooks.com/on-writing-more Links to other gardens nikitavoloboev You and your mind garden Building a digital garden A Renaissance of Open Thinking and Curated Writing on the Web Digital gardens Work with the garage door up brendex beepb00p My blog is a digital garden, not a blog Julian’s lifelog and digital playground Alex’s Notes YouTube Creators Linux The Linux Experiment Linux For Everyone Techno Tim ExplainingComputers Makers Estefannie Explains It All JetsonHacks MickMake N-O-D-E Zack’s Lab Strange Parts Maker’s Muse Make Anything

The Home Assistant Kodi Integration is nice, but as of writing it becomes slower the longer Home Assistant runs. This sucks, especially when automations (like turning on a power hungry receiver) don't run because of it.
