Helium Blockchain for Home Assistant

NOTE: This integration ONLY WORKS on the ORIGINAL Helium blockchain, and will no longer work once Helium migrates to the Solana blockchain in mid-2023.

Sensors for monitoring individual Helium hotspots, Helium blockchain wallets, and the Helium HNT/USD Oracle price for Home Assistant. For more detailed metrics, HeliumTracker gives more detailed analytics over time including dashboards for your hosts.

Installation

Make sure Home Assistant Community Store (HACS) is installed. This integration is part of the default HACS store (though can also be added manually using repository: rsnodgrass/hass-helium)

Configuration

The bare minimum configuration creates general sensors to track the Helium blockchange, notably the HNT/USD Oracle price.

sensor:
  - platform: helium

Configure sensors for Helium hotspots:

sensor:
  - platform: helium
    hotspots:
      - 112JbKk4fvYmoSqHR93vRYugjiduT1JrF8EyC86iMUWjUrmW95Mn

Configure sensors for Helium wallets:

sensor:
  - platform: helium
    wallets:
      - 12ywrqqzeNFwSMvCcaohpVdiwEeK4NZChtL9rs7dhKYd85fKG9U
      - 14YeKFGXE23yAdACj6hu5NWEcYzzKxptYbm5jHgzw9A1P1UQfMv

NOTE: By default, the sensors update from the Helium Blockchain every 15 minutes. This interval can be changed by adding a 'scan_interval' entry for the sensor, but this effects all sensors. You can create automations to dynamically trigger more frequent of specific sensors using the 'homeassistant.update_entity' service call.

Advanced Configuration

This configuration.yaml setting adds a sensor to track total HNT added to wallet by day/week/month usng the utility meter integration.

utility_meter:
  helium_wallet_today:
    source: sensor.helium_wallet_12ywrqqzeNFwSMvCcaohpVdiwEeK4NZChtL9rs7dhKYd85fKG9U
    cycle: daily

  helium_wallet_weekly:
    source: sensor.helium_wallet_12ywrqqzeNFwSMvCcaohpVdiwEeK4NZChtL9rs7dhKYd85fKG9U
    cycle: weekly

  helium_wallet_monthly:
    source: sensor.helium_wallet_12ywrqqzeNFwSMvCcaohpVdiwEeK4NZChtL9rs7dhKYd85fKG9U
    cycle: monthly

Total HNT Mined Today

This requires the advanced configuration above to add a utility meter for tracking today's HNT wallet amount versus yesterday's wallet. This requires the apexcharts-card.

Is there a way to change fiat currency from USD to EUR, GBP, CAD, etc?

No. By design, Helium HNT is currently tightly coupled with USD since both the Oracles are all in USD and the Helium DC (Data Credits) are all fixed to USD prices. However, you can of course convert from the USD price to other currencies using add on sensors.

For example, setting up conversion to CAD:

sensor:
  - platform: openexchangerates
    name: Canadian Currency
    api_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    quote: CAD

  - platform: template
      sensors:
        helium_wallet_value:
          entity_id: sensor.helium_wallet_xxxxxxxxxxxxx, sensor.helium_hnt_oracle_price
          value_template: "{{ ((states('sensor.helium_hnt_oracle_price') | float(0)  * states('sensor.helium_wallet_xxxxxxxx') | float(0)) * states('sensor.canadian_currency') | float(0)) | round(2) }}"
          unit_of_measurement: "CAD"

And a simple Lovelace display (thanks @ThaNerd):

- type: custom:apexcharts-card
  header:
    show: true
    title: Helium Wallet/CAD
    show_states: true
    colorize_states: true
  series:
    - entity: sensor.helium_wallet_value
      name: Helium Wallet
      type: column

Support

This is a community supported custom component integration for Home Assistant. Code improvents and Pull Requests are appreciated.

Community Support

• Home Assistant Community Forums
• Helium Discord

Feature Requests

• allow auto-creating sensors for ALL hotspots for a given wallet (optionally)
• create sensor for current wallet value (based on Oracle HNT price)
• create sensors or attributes for being able to display per-hotspot rewards per 24-hour, 7-day, 30-day
• disable polling to allow dynamic scan intervals (e.g. every min for price, every 15 min for hotspot avail, every hour for wallet value)

Out of Scope

• local access to Helium hotspot status from proprietary vendor APIs (e.g. Bobcat diagnosis interface) -- love this idea, but this should be a separate Home Assistant integration

Here is an example for Bobcat 300's using the RESTful sensor:

sensor:
  - platform: rest
    name: "Bobcat Helium Sync Status"
    scan_interval: 300 # 5 min
    resource: http://<your-bobcat-lan-ip>/status.json
    value_template: "{{ (value_json.miner_height|float / value_json.blockchain_height|float) | round(2) }}"
    unit_of_measurement: '%'
    json_attributes:
       - "status"
       - "miner_height"
       - "blockchain_height"
       - "gap"
       - "epoch"

  - platform: rest
    name: "Bobcat Temp 0"
    scan_interval: 305 # 5 min + 5 seconds
    resource: http://<your-bobcat-lan-ip>/temp.json
    device_class: temperature
    value_template: "{{value_json.temp0|float}}"
    unit_of_measurement: "°C"

  - platform: rest
    name: "Bobcat Temp 1"
    scan_interval: 310 # 5 min + 10 seconds
    resource: http://<your-bobcat-lan-ip>/temp.json
    device_class: temperature
    value_template: "{{value_json.temp1|float}}"
    unit_of_measurement: "°C"

  - platform: rest
    name: "Bobcat Light"
    scan_interval: 300 # 5 min
    resource: http://<your-bobcat-lan-ip>/led.json
    value_template: "{{value_json.led}}"
    unit_of_measurement: "color"

Note: If you make multiple calls on bobcat API, make sure that you make unsynchronized calls in order to avoid the bobcat API error 'rate limit exceeded'.
