Good morning,
I’m new to Home Assistant but I’m looking for a solution if it’s possible.
They installed photovoltaic panels with the “Fronius” inverter, the Emmeti boiler with the “Febos Energy” system (https://emmeti.com/en/products/air-conditioning/residential-inverter-air-to-water-heat-pumps/air-to-water-heat-pump-mirai-smi-febos-4-0/febos-energy) and the “Febos Crono” (https://emmeti.com/en/products/air-conditioning/residential-inverter-air-to-water-heat-pumps/air-to-water-heat-pump-mirai-smi-febos-4-0/febos-crono) from where you can see all the energy of the house and also that of the panels. I saw in the manual that the Febos Energy communicates with the Febos Crono via the Modbus RS465. My question is: is it possible to make everything communicate with the Home Assistant? See the electricity produced by the panels, consumed by the house and consumption in real-time.
Thank you
hi. have found any solution for this?
I’m also looking for such an integration.
I made such an integration using the Febos WebApp
Using some curl, jq, and a shell script to dump all parameters to json; and that json is ingested in HA.
Script runs every 30s and updates the dashboard.
This will require some coding skills. Maybe this will give you some ideas. Don’t want to share the code since I am not adhering to the ToC of the service…
How do you do?
Can you share the code and how to do it?
No, as said before I am ‘abusing’ the website to pull the data. If you can code, you can figure it out. if you cannot code, you should not be running this as it requires understanding of what you are doing.
I am working on a solution that does not require the online components. I intent to listen to the modbus communication (the ‘wires’ between the febos crono and the heatpump) and sending that data to HA using MQTT. Once I have a working prototype I will share the code.
Thanks for that. Looking forward to it
Got some part running, but unfortunately the “internal” status (like room temperature) is not exposed on the modbus. And some values do not make sense atm.
That’s great news, do you still have to test it or can you share the code?
how do you do this?
i have a rs485 adapter connected to the end of the bus. the program i use to read the data is “modscan32” but i can’t read anything.
I don’t have it connected to the end of the bus, but rather in the middle (connected two extra wires to my Febos Energy. I removed R7 from the RS485 adapter per these instructions: RS485 sniffer
I then compiled this code: modbus-sniffer/README.md at 8720c4649a29e2090f9a7d363eed15cdc9a5f5ab · alerighi/modbus-sniffer · GitHub. (all Linux and Raspberry Pi)
Speed of the bus is 9600 baud, no stop bits, theoretically Even parity. Ensure that you have connected the A and B wires correctly to the converter, and power it with 3.3 volts only (otherwise you will damage your Pi or ESP32).
– EDIT –
Also, modscan32 per it’s website is a Client device. You cannot have 2 clients on a Modbus (the other being your Febos Crono). If you insist on running a 2nd client device, ask the heatpump (id 3) for a register value (e.g. 8986, outside temperature).
These are all the registers I pulled from the website and other sources. Some of these registers are never exposed on the modbus as they are internal to the Febos Crono:

but does this solution also work with Febos Energy or do you always need a separate/additional modbus?
Thanks
There is only ONE modbus. The modbus communicates between the Febos Crono and the heatpump. The Febos Energy is an optional add-on. It was an easy point for me to connect the modbus device to. But you don’t need it.
I think it is wise to read up on how modbus actually works before connecting things to it. Otherwise things might break… See for instance this link (RS485 sniffer), chapter HW setup. This explains a bit about ModBus
ok, I’m not an expert on these things, so I didn’t understand one thing, if I have the Febos Energy what do I have to do to connect it to the home assistant?
Thanks
edit:
I have this device, could it be useful to me? USB to RS485
I still haven’t been able to connect to the bus. However, at the IP address of the Febus Crono I was able to find this file: emmeti-374-config.json
There are all the values present with the unit of measurement, the type of data and other parameters indicated.
I also checked the website of the app “emmeti.aq-iot.net” and the parameters that can be modified, at least in my case, are only the following:
8683 = season = boolean = 0/1 = 0 cold water for summer = 1 hot waret for winter
8676 = manual presence = boolean = 0/1 = 1 not present = 0 present
8685 = comfort time (summer) = integer = number value for time (ex: 540 mean 09:00)
8687 = attenuation time (summer) = integer = number value for time
8689 = comfort time (winter) = integer = number value for time
8691 = attenuation time (winter) = integer = number value for time
8684 = comfort temp (summer) = integer = number for temp (ex: 251 mean 25.1°C)
8688 = comfort temp (winter) = integer = number for temp
8686 = attenuation temp (summer) = integer = number for temp
8690 = attenuation temp (winter) = integer = number for temp
8660 = humidity for summer = integer = number for humidity
8661 = humidity for winter = integer = number for humidity
16384 = heat-pump On/Off = boolean = 0/1 = 0 off = 1 on
8692 = boost = boolean = 0/1 = 0 off = 1 on
16497 = domestic hot water holding temp = integer = number for temp
16494 = temp domestic hot water t1 = integer = number for temp
16496 = temp domestic hot water t2 = integer = number for temp
16493 = time domestic hot water t1 = integer = number value for time
16495 = time domestic hot water t2 = integer = number value for time
I have the same device. This to be exact. I tried to connect to various points of the bus but without success. I also tried to remove the febus-crono but I still can’t read any value.
You’re on the right way. Use a bit of curl, get the token, call the webservice, and be golden…
You have to listen to the modbus. Do not inject reads or whatever. Just listen, the Crono will retrieve registers from the heat pump and optionally Febos Energy.
With this code I am able to sniff the bus and get the results like this:

This is for instance an interesting one: 01 03 23 18 00 0E 4F 8D
Decode it using Online Modbus RTU Parser & Modbus TCP Parser and find that this is the client (Crono) reading (0x03) server 01 (the heat pump) for register 8984 (0x1218), quantity 14 (0x000E).
The response: 01 03 1C 01 48 00 F8 01 A1 01 7B 02 29 7F FF 7F FF FF A2 00 00 00 00 00 00 7F FF 7F FF 00 00 65 F6
gives the values for the registers: 0x0148 (328), 0x00F8 (248), 0x01A1 (417), 0x017B (379), 0x0229 (553), 0x7FFF (32767), 0x7FFF (32767), 0xFFA2 (65442), 0x0000 (0), 0x0000 (0), 0x0000 (0), 0x7FFF (32767), 0x7FFF (32767), 0x0000 (0)
Now the 2nd value is register 8986 (outside temp) which was at the time of the scan 24.8 degrees (I verified this with the website). This is how I am trying to play with this.
