I used the Sense S2 all of 2024 with minimal issues. Installation was straight forward. Unit worked flawlessly except for a few times when a daily reading would spike for a day or two then go back to normal. A quick test with reagents confirmed the cartridge missread. I believe these were caused by water flow issues in skimmer. Overall a great product and value.

Hi! McKinney~We appreciate you sharing your experience! It’s great to hear that the setup went smoothly and the system performed reliably. Occasional fluctuations can happen due to water circulation, and verifying accuracy with reagent tests is a great approach. Thank you for your support!

The WaterGuru Sense S2 is great. No more running to the pool store. I just wish i could control when it checks the pool water. I think every day is overkill. I would like an option to schedule my checks for when it's convenient for me. Also, I would like to see a cartridge capable of measuring salt. Otherwise, I love the product it works extremely well.

Thanks for your feedback! The device tests daily to ensure you don’t miss any chemical changes. We understand the need for scheduling flexibility and will share any updates on this. As for salt measurement, we're working on it and will announce when available. Glad you're enjoying the product! Let us know if you ever need anything.

I have tried most of the pool chemistry monitors on the market and WaterGuru is the only one I found to be reliable. Others gave inaccurate reading or failed altogether. After using the original Sense for a number of years, I upgraded to the Sense S2 primarily to monitory CYA. As I use Home Assistant (HA) for my Smart Home, I can use the integration to monitor the pool directly in HA. If you have a pool, I highly recommend WaterGuru for monitoring and managing pool chemistry.
