thanks sebastianb, yes we’ve used 3 types of water meters, and these generally have an ‘alarm’ mode for tampering (i.e. sent as what we would call an ‘event’ rather than a periodic status reading) as well as sending their usage data periodically. FWIW I have not seen an example where the water meter sends a timely water-related ‘event’ such as (simplest) usage exceeding a threshold - I could imagine more sophisticated events like ‘usage not normal’. The meters are pretty impressive in terms of specification… waterproof with a 25-year (lifetime) battery life - sending 24 readings per day batched into a message every 12 hours.
The meters we’ve tested are from Diehl, Arad and Itron - I browsed around for links but most of these things are still in the development/evaluation stage (as understandably there’s a dependency on an available LoraWAN network which the water companies, in the main, don’t yet have).
