8. pHin from Hayward
The pHin service is discontinued. Please read our dedicated article for more information. Also, if you have a pHin, you can connect it to the iopool app. We have created a dedicated page that explains how you can achieve it. Don't worry, it's very simple to do (aka you don't need to be an engineer, anyone can do it in less than 5')! Please be aware that the pHin bridge isn't usable in this case so you can access your pool data only if you're close enough to establish a Bluetooth connection.
