I would be interested to learn what you hear from BGE. For what it’s worth, I reached out to Rainforest last summer about the compatibility of their energy gateways with BGE smart meters. Rainforest responded that, although their EAGLE-200 energy gateway is compatible with the model of smart meter that BGE uses, BGE has not yet enabled their smart meters to connect to third-party monitoring devices like those made by Rainforest. If was unclear if or when BGE intended to enable that functionality.
It’s painful that we as consumers are paying for these ‘smart meters’, but it seems for a large number of the utilities, water, gas, electric, the only benefit is to the utility to reduce their cost to bill us!!!
Just an FYI, the Rainforest EMU-2 units seem to be readily available from Amazon. The more expensive devices from Rainforest and Vue seem to be out of stock quite a bit. Back on soap box here, I struggle with the ‘value’ of these more expensive devices that upload your usage data to their servers. In theory to give you back more insights to your usage or possible to control HVAC or electrical load via their (it appears) proprietary wifi or zigbee devices. For being here in a self done Home Automation forum, IMHO it is much better to just get the raw whole house power usage and do your own analysis and control.
I hope you all find a way to get this data into Home Assistant, I have found it very useful.
Good hunting!
I reached out again to Rainforest to ask whether there has been any progress with BGE. They reported that they have had “good meetings” with BGE over the past few months, and they expect to start a pilot program for BGE customers soon. Fingers crossed!
I have yet to get any reply whatsoever from BGE. If I do ever receive a message from them, I’ll post it here.
I have the same meter and reached out to my provider (SMUD)
The response was “We don’t provide the capability for third-parties to sync with the device for security reasons”
Anyone come up with any kind of solution for BGE Electric and Gas meters?
I have not, yet. I’ll probably just get an IoTaWatt this year. I don’t have BGE gas at this house, so I’m not sure about that.
Checking in about a year and a half later… @ha.fan have you heard anything from BGE or come up with a solution for real-time data otherwise?
I have this exact same meter in my house and am trying to figure out the easiest way to get usage info into HA.
Bumping again, interested in doing same thing. Looking for options.
- Esp32
- 2x 100/200 A CT clamps
- 1x ads1115
- 2x 10k resistors
- 1x 10uf capacitor
- proto board
Solder together a small esp setup to monitor your power.
The other option is to buy a ready made system. I know the emporia vue 1 and 2 are able to be flashed to esphome. Idk for sure about vue 3, but I imagine it’s flashable too. I saw a post where someone confirmed the vue 3 esp32 isn’t bootloader locked.
This way you never have to rely on your service provider to enable and maintain the zigbee setup, everything will be local and if anything breaks or goes wrong, you can fix it yourself without needing to call the service provider.
You describe the parts for a current meter - how would you measure (AC) power with this setup? 
You can either guesstimate using what your mains voltage should be (120 for Canada here), or you can use a zmpt-101b to actually measure the mains voltage directly at the load, or use a transformer to drop your mains to x V for measurement. The other option is something like a zigbee plug or similar that measures the mains voltage.
Then it’s as simple as x A * y V = watts for active power.
Photovoltaics will need a different setup, usually the controller has facilities for this.
Esphome example of my voltage reading for the moment (screenshot as I can’t copy n paste on mobile from esphome or vscode):
I guessed 
Not in my world
Amperage multiplied by Volt equals Volt-amperes which is (only) the apparent power.
A * V = VA = watts for apparent power 
And for real world scenarios (residential usage/billing for example) the apparent power doesn’t matter because only active power is metered and billed 
It seems my signature doesn’t need an update after all 
I’ve seen you around and notice this is your schtick. You seem to have a superiority complex and believe you’re a genius.
I think you should spend your time working on your ego and mental health rather than trying to feel superior by dumping on people offering other people real world solutions.
Have a great day!
Edit: also, maybe take a look at the community guidelines if you care about your fellow Hass forum user. As hard as this may be for you to comprehend, the world doesn’t revolve around you.
…just pointed out that your “solution” isn’t any for a real world scenario
Instead of building a current meter it’s easy enough to just build a power meter 
A pzem004tv3 and any esphome capable MCU is all that’s needed 
You’re way too cool for me to be replying bud
Don’t be sad. You will learn from your failures, as did others before you
And for sure you will not be the last person on earth (or this forum) which doesn’t get the difference between current and power meters
And to repeat the thing you don’t want to hear (or why your solution is waste time/life) 
Waiting for my custom pcbs and my atm90e36 ic’s. I find esphome and emonlib too slow to do the phase shift calcs.
Congrats 
Finally a real power/energy meter 
This way you will be finally able to have accurate active power and not (useless) apparent power readings.
Now this should cover some “real world scenarios” finally
Thanks, any other advice sweetheart? Or are you done stroking your ego?
