    I use powerpal for this. Getting it to work with homeassistant was very hard, this looks like the pay-to-win option

      if you could share how did you integrate with HA? I guess you used esp32 for Bluetooth proxy but how did you get api from powerpal?

      • shiggaz on 02/12/2024 - 10:53

        It was very hard. You are right, I used an esp32 with Bluetooth and poll the powerpal for data. That gets pushed. I'll find my config for you

        • Gaggy boy on 02/12/2024 - 10:58

          please and thanks.

          So curious what you using the shellypro for?

          Also did you install it into switchboard yourself?

    Single phase

      actually, not really - this 3 Phase can be used for 3 seperate 1 phase circuits….
      i.e. Solar production, Grid consumption and 'one other' (could be house consumption and grid, then math in home assistant to show self consumption vs grid)

      Shelly Pro EM-50 is a single-phase, two-channel energy meter. It includes 2x 50A CT clamps.

      Shelly Pro 3EM is a three-phase, three channel energy meter. It includes 3x 120A CT clamps.
      This can also be setup to monitor three individual circuits on a single-phase power board.
      ^^This is is my use case.

    • MKBHD on 02/12/2024 - 11:04

      Does this have RCM tick?

      • inrover on 02/12/2024 - 12:28

        The ones sold in Australia do.
        I expect this is applied per model so may be applicable

      • helldoodle on 03/12/2024 - 21:27

        the german one, no, i have one in my spares box due to a miss buy last year

  • guidedlight on 02/12/2024 - 10:48

    Does this have a RCM mark to demonstrate it is compliant with Australian regulations?

    Personally I wouldn’t purchase something from Germany and install it in a meter box in Australia, it’s just asking for trouble.

    Also nowhere on the description does it mention it is for 3-phase only.

    • Man10United on 02/12/2024 - 20:18

      Yeah, the other day, this was being asked on the HA AU/NZ facebook group that is it alright to import this product (or any shelly) from other countries. There was mixed answers, but mostly vaguely said no don't. Personally I think it's identical to the one you could buy locally. But need someone to actually confirm it has the tick logo…

  • MKBHD on 02/12/2024 - 11:05

    Looking for something similar to control my hot water but single phase with an RCM tick. The dumb timer is no good due to low FIT and unpredictable rains.

    • bleugh on 02/12/2024 - 12:08

      you'd need to also order a contactor of a suitable rating to be driven from the 'dry contact' outputs of the SHelly device

      i have for example a 4.8kW hot water sysem (20A)…
      i'd need at least a 30A capable contactor which is de-rated for our Auzzie hot weather

      So, This device + contactor + sparky to fit, perfect

      don't forget also if you have a Controlled load plan, you can't switch your own hot water out of the circuit
      if you want controlled load AND solar…….you need a tank with a fancy two element system, OR use a solar diverter / solar aware relay system that lets controlled load take over

      • MKBHD on 02/12/2024 - 12:20

        Thanks for the headsup about the rating, didn't think of that but will keep that in mind.

        I did have the hot water on controlled load but after installing solar, I got a separate sparkie come in to rewire the hot water cirtuit to the mains and install a dumb timer alongside the breaker for a few hunderd dollars. The CL line/meter now sits there not disconnected but I still pay for its supply charge ~12c a day or sth like that. I have read its costly to have the CL meter removed by energex. Now I wanna replace the dumb timer with something with WiFi that supports home assistant (catch power doesn't support HA yet)

        • bleugh on 02/12/2024 - 12:23

          there's solar diverters - Paladin, Solardiverter and catch, a little more expensive, but send EVERY watt to the hot water. the issue with standard relays is they're programmed to only send extra excess solar to the hot water…..i.e. 2.4kw, THEN you'll heat hot water…every kW before then gets dumped to grid!

          • MKBHD on 02/12/2024 - 13:40

            @bleugh: would that also need a special water heater tank to support EVERY watt? The one I currently have seems to be about 15Amps but I am not sure if I can run it any lower with those devices, this is very exciting.

            • bleugh on 02/12/2024 - 13:58

              @MKBHD: not really, most are resistive element. YOu just gotta watch with old ones as they may not like it much

  • glitch23 on 02/12/2024 - 13:03

    I see Shelly relays and this Power Monitor.
    Is there anything from Shelly that does both Power Monitoring and Power Control Relay?

    • bleugh on 02/12/2024 - 13:07

      yes

    • bleugh on 02/12/2024 - 13:08

      Shelly PRO 4PM Relay Switch is ONE example of the multiple products in the Shelly range

      • glitch23 on 02/12/2024 - 13:09

        thanks, will check it out

        • bleugh on 02/12/2024 - 13:12

          it's by far the best value one….I had 4 of them in my basket last year to buy,
          BUT, only rated to 40 Degrees…
          so, not suitable for use in my outside distribution box :-( and too expensive to move the box, so….no central power control for me! (I use an IotaWatt for monitoring though)
