Home Assistant Setup Instructions
These instructions are provided courtesy of @sonapsent
The following shows how nodejs-poolController can be integrated into Home Assistant. This allows everything smart home related to be controlled from a central platform and provide additional local automation for a swimming pool. After setup it is possiable to create notifcations, view historical data/graphs, or even connect to voice services like Google or Alexa within Home Assistant.
Disclaimer: Myself and others involved in nodejs-poolController are not responsiable for damage to equipment, thermonuclear war, or other harm to personnel. Controlling industrial equipment is serious so please monitor the system and thoroughly test your setup.
- Controller: [e.g. Nixie Single Body (nodejs-PC v7.2)]
- 30,000 Gallon In-Ground Pool
- Pump manufacturer and model: [e.g. V-Green 165 VS Motor / Stealth Pump, relay control]
- Filter: [Pressure Gauge]
- Temperature Sensors: [ 10k thermistors for water and air]
- Chemical controller: [e.g. REMChem, Atlas EZO ORP and PH]
- Heater(s): [e.g. Heatpump, relay control]
- Chlorinator: [e.g. Aquarite 900, RS485]
The instructions below assume that both nodejs-PoolController and Home Assistant are setup and running independently. Please ensure that pool devices are working within the web based dashPanel before continuing.
nodejs-poolController:
- Enable MQTT on dashPanel
- Optional: Enable MQTT on REM (for pressure sensor)
Home Assistant Add-Ons:
- MQTT Broker
- NodeRed
- Visual Studio Code (or other various text editors)
- Optional: HACS
The following sections can be added to the appropriate sections in your HA configuration.yaml file depending on what equipment you have. Pay attention to the rootTopic text for your setup as the default will be different depending on controller setup. In the example below this has been simplified to "pool" for state_topic. The use of an application like MQTT Explorer is valuable for troubleshooting and monitoring messages in real time.
After the configuration file is saved it is nessary to restart HA for new entities to be created or changes to take place.

You will need the following or similar automations to keep the temperature and/or chlorinator set points synchronized between nodejs-poolController and Home Assistant. You will need to remap references to your specific HA and MQTT servers in node-red after importing the code below.

At this point you can make any automation you can dream up. If you need any ideas to start with, here is a list of some of mine.
- Logic to toggle pool "on" state and select pump speeds while keeping them sync'd with nodejs-poolController
- Schedule for the pool pump
- Avoid using electricity during peak hours
- Turn the heat pump on only for days that pool is likely to be used
- Notification if communication drops from the nodejs-poolController (ex: monitor the pressure value for "unavailable", as the MQTT value is setup to expire after 10 minutes)
Of course another way of doing automations in HA is to simply using yaml. The following two automations should keep the chorinator set point synchronized in both directions.
