Hi @Audra,
Late to the topic, but I would not say that IoT is a tired topic in the industry. I'm an active member of the IoT Alliance Australia, and regularly (monthly) attend a forum of water utilities discussing IoT in the water sector here in Australia and we are not even talking about digital metering as it's a tired topic :-) because it's 'been done' to death, and every utility here in Australia is either rolling them out, or about to roll out, or completed their pilot.
There are various IoT use cases being deployed, piloted or in the POC/POV process. These include IoT being used for water quality monitoring (in dams, creeks, etc.) flood level monitoring, sewage pipe inspection, etc.
The water sector here is developing an IoT guideline for the entire Australian water sector (it is also based on an IoT guideline/tool that I have developed for a utility prior as well as a Digital Reference Framework for the Water Sector, again based on an IoT Ref Framework which I also helped develop). And happening most recently, an IoT Water Hub has been set up to help develop/create IoT value for the water industry, which comprises of Academia, industry partners, and organisations like the IoT Alliance Australia.
But I must say the take-up of IoT-based projects is still nascent in the water sector, as there is still much to be done/educated. There is still a SCADA vs IoT mentality (and will be for a while), as IoT is still seen as not being secure enough (rightly or wrongly) to be used for control purposes (as in controlling actuators). I would say each Water Utility would have a different maturity approach to IoT.
In the Energy sector, my involvement is only scratching the surface at the moment, but I have seen presentations from energy generation companies using IoT as a complimentary solution mostly for monitoring the environment, especially in the case of renewable energy.
I have been involved in reviewing cybersecurity in the Microgrid space, and I treat DERS (Battery systems, EV charger, solar PVs, etc.,) as IoT endpoints. I recently found out that NIST 'classifies' DERs (in microgrids) as Industrial IoT (so I was most happy).
I'm currently 'trying' to see how IoT can be applied in (what we call in Australia) Renewable Energy Zones (REZ)s. If you're interested, you can search for REZs in Australia.
