Battery Eater - confirmed!

Initially the sensor worked as expected with a battery life of about 3 months over the winter months. Thereafter batteries would only last about a week. I took it back to bunnings as faulty. Just put the new one in and it has chewed the batteries in only 2 weeks! Perhaps the sensors cannot take the heat! It is installed out in the full afternoon sun near the driveway where temperatures can get quite high.

Battery eater

Chews through the batteries in 8 days. Plus no warning of low battery on app.

Hi Duncan, thank you for leaving a review. It certainly sounds like you have a faulty unit. Please get in touch with our support team and they can assist you with further troubleshooting.


The battery life of the moisture sensor is about two days as far as I can tell, at least with the "battery life" indicator switched on. Furthermore, the WX1 tap timer battery cassette has extremely thin and weak battery contacts that bend easily and give poor connections - leading to an "offline" indication until you remove the batteries and rebend the contacts.

It's a pity that the Holman Wi-Fi system doesn't (so far) live up to the quality standards of the rest of Holmans products. I hesitate to label it useless consumer junk just yet. No matter what features and how convenient it is, if it isn't reliable then that's what it will be.

My gardens have cost me many thousands of dollars and countless hours to establish. We live in country Victoria where it gets very hot in summer. I MUST have a reliable watering system for when I'm many miles from home. If this stuff doesnt work reliably, then its back to the less convenient Hydrawise system.

Hi Fizz,
Thanks so much for taking the time to review our Moisture Sensor. It looks like you have a faulty unit, as the battery life indicator should not be making an inaccurate reading.
Could you please contact customer service at, they will be able to assist you further.

Moisture Meter

Over the last 12 months I have purchased a number of Holman Products choosing them being an Australian Product plus quality. I had some necessary requirements of a product which I could work safely and confidently from a remote location. Prior to purchase I had a number of queries and questions as to would this product fulfill my requirements which I was always promptly and accurately given a response. Based on this I committed and based on the performance I have extended the range of products with complete confidence. In particular I would acknowledge Krys in support who answered, addressed and tolerated me with all my issues and resolved all my issues beyond my expectations. I recommend the product, I appreciate the support and enjoy the product. 👍👍👍
