Hello,
I’m in the UK and my water supply company, Severn Trent have just fitted me with a smart water meter. I can login on line and view readings but anyone have a clue on how I can integrate this with the energy dashboard in HA please?
Same one as me. I rang back and they said:
“While you now have a smart water meter, we need to get a reciever fitted in your area to collect the data” 
I also asked about an API to collect the data, but the guy didn’t know what I meant.
I’ll keep the thread updated.
Cyble 5 is the meter
This may be a good link to look at : Domotizes the Itron water meter with esp and cc1101 in ha for 10€ - Haade.fr
Would need to change 4 find the right frequency for your CC1101 transmitter
as the STW looks like its using 868mhz, also not sure as long as Severn Trent have not done anything odd.
I am still waiting on my smart meter which is due in 1 week…
If you do manage to get something working keep me updated.
I can now login to the Severn Trent portal and view hourly water consumption but no idea now to get this data pulled into HA. I presume there is some sort of API url but now idea how to find this.
interestingly my Severn Trent meter is using 433Mhz. Im going to attempt the above to get mine working, will report back if I get it going!
Also here, in Italy, the water company installed a Cyble 5. Any idea how to collect data? The protocol is LoRa 868 MHz?
Hey
Did anyone get any further with this one for Severn Trent Water in UK?
I have exactly the same meter.
Did anyone make any progress on this at all?
It looks as though Severn Trent have plans to roll this out wider: Smart Metering Project | Green recovery | Wonderful on Tap | Severn Trent Water
I had a conversation with them in Jan:
[07/01/2025, 13:24:52] Steve Baxter: So an API i a way of querying billing data automatically. In this case I would like to pull the billing and usage data into Home Assistant (I use this for controlling lots of things around the house). Octopus have this for energy usage for example.
[07/01/2025, 13:25:13] Steve Baxter: For example, other people are asking here Severn Trent Smart Water Meter
[07/01/2025, 13:25:34] Steve Baxter: This is a technical query and probably needs to go to whoever maintains your billing and usage system.
[07/01/2025, 13:25:48] Steve Baxter: (they will know what I mean by an API)
[07/01/2025, 14:34:20] Severn Trent: Apologises for the delay in response. I am currently looking into this for you.
[07/01/2025, 14:54:47] Severn Trent: I’ve spoken with one of our Project Managers I have been advised it isn’t something Severn Trent currently offer unfortunately, is there anything else I can assist you with today ?
[07/01/2025, 15:09:04] Steve Baxter: Thanks. Can I request that this is something you look at?
[07/01/2025, 15:10:43] Severn Trent: Sorry this doesn’t appear to be something Severn Trent is currently in the process of actioning.
