Image Install Method

Oasis Spa can be installed most simply by starting with a full pre-installed image. This method will allow you to simply download a full OS image and drop it on a SD card, put it in a Pi and boot it up. The only thing to do is to configure the web interface and if your tub has MQTT devices configure the Hallonlarm.config file.

In this WIKI page, the only instructions supplied are high-level. I'll assume you know you how to image your RPi SD card and boot it up.

check the releases, download the latest image file
Unzip it
Use some sort of image writing program such as Etcher to write the file
Put it in your Raspberry and boot it.
Run 'raspi-config' to setup stuff, and things
- Expand File system -> reboot
Figure out your Network Settings
Open a browser, the DNS name of Oasis Spa is http://Oasis-Spa you may have to use http://RPi-IPADDRESS if dns isn't working for you.
Configure Switches/Relays, Sensors to your specific setup. If you are going full IoT, then the quickest way is to have your Pump listen to tub/pump/relay/0 and tub/heater/relay/0 this is the default Hallonlarm.conf setup. Sensors need to be individulally configured, see Sensors Wiki section.
