Swimming Pool Floating sensor?

Hi

I have done quite some research here in forum and on Internet but not much success so far. I’m looking for a floating sensor for a swimming-pool that would be able to send usual measures used for a chlore swimming pool. I can’t imagine such product doesn’t exist ??

Thanks

No one on this ? I found the sensor of Waterair but they do closed Lorawan with their own gw and not willing at all to make it usable on other Lora network than their closed system :frowning:
