Smart Meter and Home Assistant

    I use Home Assistant to control things such as my lights, Thermostats and other things.

    Home Assistant received an update which includes a Energy Management component (2021.8).

    To utilize this there is two products one which utilizes the P1 port and the other for systems that do not have a P1 port.

    Presently we have the anaolg meter.

    Does the smart meter have a P1 port ?

    ESB recently upgraded our meter - the model they installed was a Kamstrup 8660 which, as far as I can see, doesn't have a P1 port.

    For power monitoring, I've been using a Shelly 3EM which is overkill on a single-phase system (but I liked the DIN format). However, I haven't yet investigated if/how this will work with the new HA Energy Management component...

    Hope that's useful and let me know how you get on 😊

    Finally received a reply from ESB:

    ESB Networks does not provide this. Some suppliers do offer a unit from time to time, so it may be worth contacting your supplier directly.

    Do any of the ROI smart electricity meters allow local access, or will any data have to be collected from a cloud service? Are any of the ROI electricity providers exposing any of this data to consumers yet?

    I'd find it hard to see them being able to justify refusing access to one's own data.

    I've a smart plan with EI, and they allow you to download your data in CSV format from your online account page.

    Very interested in this.

    There is an interesting project based on the same meter using an ESP8266 to publish the data to MQTT.

    I cannot post links but Google:

    "Using ESP8266 to monitor Kamstrup Omnipower" and you should find it.

    The "HAN" port on my meter has a tamper seal on it, is it an offence to remove the seal?

    Hi Capt. Insano,

    Thank you for getting in touch.

    it is illegal to tamper with a meter.

    ESB Networks maintain the electricity network for all electricity suppliers. We recommend contacting ESB Networks directly if you wish to ask them about the tamper seal. Their contact number is 1800 372 757 for geneeral queries and their email is [email protected].

    Kind regards,

    So, just to clarify, Aoife - you're saying that we would need to speak to ESB about getting a P1 port unlocked?

    But ESB have said that we would need to contact our supplier directly (which sounds like they mean Electric Ireland) as they can't help...?
