Starting a new thread as this was getting lost in the Hints, Tips & Troubleshooting thread.
Post details of your integration with Home Assistant etc.
Just on the SDM230.
My main consumer unit is on my house and I have a sub unit in my garage, which is where the inverters are. If I install the SDM230 to the sub unit and wire Live/Neutral IN from the sub board breaker and OUT to the Inverter Rcb0 will that work?
Or do I need to install the SDM230 next to my main 80A MCB on the main consumer unit, in which case I'd have to run both network cable and power OUT to the garage
I should mention my Meter is on my garage wall, so it was easy for me to connect the CT and run it into the garage
I believe you need to pass the L/N from your main breaker (the one going to the esb meter) through it so it can read this correctly, no different than you're supposed to install the CT
Deye support said to use the V1 of the SDM230.
@unkel can confirm, he installed one. I need to do the same soon
The CTs on my emontx are spot on. It matches what the smart meter download reports anyway.
The small transients you'll never cut out, but won't amount to much anyway.
New heatpumps are inverter driven so they ramp up nicely Vs starting with full power from the word go.
SDM230 seems harder to locate locally (unless you have a link). The V2 is more widely available, will this work?
Yep pass main L/N through the meter, then just two wires RS485 connected to meter and the other end (RJ45 connector) into the inverter
I used the V2 Eastron from Amazon:
well now, I don't hate this, but also, thinking about just creating a shower time reminder...
FYI this is working as I'm using it myself. The new HA update has hidden the "aux heat" button in climate though. Ie the boost. But I worked around using an automation and a button on the dashboard
Thanks, can you tell me how you got it working. I pasted the code in the configuration.yaml file, put in my email and password. What else is needed?
My config is just this (I have my emberpassword in a secrets.yaml
climate:
- platform: ephember
username: <email for ember >
password: !secret emberPassword
Then add the "Thermostat Card" to your dashboard, there should be one for each zone you have.
if still no dice then update home assistant as it is definitely working with any of the 2024 versions
Much appreciated, thanks.
Anybody got a recommendation for an electrician serving the Dublin area who could install a Shelly EM on my heat pump circuit? Please DM me with details...thanks!
Location?
Sorry Dublin.
I could send you pics of mine one wired if that helps _ fairly straight forward?
That would be great thanks :)
I did a bit of a write up on installing the ShellyEM back in 2022 here is the link to it....all I woudl say its pretty simple if you have a bit of knowledg (which is a dangerous thing 😉)...but you are messing about in your main board and you do have to be VERY careful and if you are not comfortable then get a sparky in. Turn the main fuse even in your meter box.
Here is the write up anyway
Power / Electricity Apps? — boards.ie - Now Ye're Talkin'
Have a few panels and Hoymiles micro inverter to set up but have got Opendtu running on an ESP32 with display, a lot cheaper than Hoymiles own DTU.
MQTT enabled so can feed the data back to Loxone for any automations and data retrieval.
Hi folks,
I'm looking for a recommendation for a temperature sensor with probe that I can use on my pre insulated hot water cylinder. One that easily integrated with home assistant..I have a plug nearby so a mains powered one or battery thats WiFi enabled etc I have a sensor at the top and bottom of the tank via the eddi but would like to keep an eye on the water temps as water is used.
Cheers
Mick
The eddi add on board can take two temp probes. The probes themselves are easy to get and cheap, got mine on Amazon.
Yeah I'm using those two already Unkel just want to add a third
Esp8266 running tasmota (or esp home) and a ds18b20 temperature sensor. Will integrate easily with home assistant. It's a DIY job though
Thanks looking as this.. seems to work

Thought I'd share my setup for anyone that's interested.
It's a fairly simple and basic but has worked well over the winter months.
Basically I look at my predicted usage tomorrow during peak period (8am to 11pm for winter), solar forecast and SOC at 10:55pm. If there is a shortfall, I set the time 23:00 to 8:00 and set the current to what's required to make up the shortfall. If there's no shortfall, no charge will be required.
I found with the above though, when no charge was required, the battery would drain over night and I'd end up importing in the morning at peak rate till the sun came up. So I introduced a boost charge function. I normally leave this set at 0.5kW, (settable 0-10kWh) it just adds that value to the current SOC at 11pm. Bit crude but it works, no discharge overnight.
Summer toggle just changes the time to midnight to 9am.
Next mod I'd like to make is to automate the usage tomorrow figure to be an average of the previous 7 days house usage during peak hours. Haven't a clue how to go about it but will figure it out.
I've got all this working using the wave share devices and the Solax integration. I poll every 15 seconds for HA and still have full usage of the solis app.
On the coding side I used the jevjev setup as a starting point but have pretty much modded that completely to suit my own needs.
Also posted over in the IoT forum, but Lidl have their ZigBee Smart Plugs (with energy monitoring) back in stock from today.
I have HA with energy monitoring via myenergi (also have a shelly EM set up).
What is the easiest way to switch a smart socket based on export ?
Set up an automation to monitor the myenergi grid CT and add a trigger to fire when the value is above a threshold for X mins, switch on smart plug. Add another trigger for when the grid ct is importing or below a certain value to turn off the plug.
Other way to do it is to let the eddi do the export monitoring and use the add-on board to trigger a relay when exporting and feed that into HA using an esp32 or something.
Ha,
Much easier than expected. Quick google showed all sorts of shite
Did a quick test there and all working as expected.
Thank you.
Hi there, I am looking for some control of my inverter and close to real-time usage graphs from my Sofar (5.5 KTL-EP) HYD 3K~6K-EP inverter with Wi-Fi data logger (LS3_15_270A_1.68).
Do I need to purchase additional hardware needed to successfully connect my inverter to Home Assistant?
I have been advised to buy a LSE3 Datalogger but I just want to make sure I need it before I make the purchase.
The main reason I need this is to force discharge of my batteries before my charging window at 2.00am starts.
Thanks :)
Best option is to get / build a "sofar2mqtt". Google search is your friend.
Thank you, I'll take a look now.
