Danfoss Eco bluetooth valve thermostat

Jacob_Hansen · August 18, 2021, 3:09pm

hi. and thank you very much for responding. well.

i am using hassio on a older dell desktop PC

from my own logic i have found that the bluetooth link must be working because i can retrieve the mac adress and the key.
i am not too sure if i have it all setup correctly. from the log etrv2mqtt it tells me i am connected to mqtt.
this is the full log etrv2mqtt log - Pastebin.com
i am not 100% sure if i have the correct values in the configurations.
here is my setup (think i got what is important) danfoss hassio setup - Pastebin.com
general error log gives me a great deal of errors. but i think they are related to the fact that i am unable to retrieve any data from the danfos device hassio errors - Pastebin.com

i was wondering if you are using raspberry pi 4 with built in bluetooth ?

Jacob_Hansen · August 18, 2021, 4:04pm

by the way. i did skip this step

sudo apt install bluez-tools bluez bluez-firmware bluez-hcidump pi-bluetooth

because it is not installed on a raspberry pi. perhaps that is the issue.

i am now trying to install it. but im pretty sure it is not possible because “apt” is not installed on this build.

(currently creating backup)

Hi Jacob,

In the etrv2mqtt log: it connects to the MQTT server but fails on trying to connect to the thermostat

2021-08-18 16:48:16.275 | DEBUG    | libetrv.device:connect:54 - Trying connect to 00:04:2f:94:95:5b
2021-08-18 16:48:23.206 | ERROR    | libetrv.device:connect:68 - Unable connect to 00:04:2f:94:95:5b. Retrying in 100ms

Traceback (most recent call last):

I am not sure but I guess it uses Bluetooth to poll the device.

In the main log I can see you have errors related to all your Danfoss sensors but with the same reason like this

2021-08-17 23:11:41 ERROR (MainThread) [homeassistant.components.climate] Platform mqtt does not generate unique IDs. ID 00_04_2f_94_95_5b_thermostat already exists - ignoring climate.sovevaerelse_thermostat

So this looks like something wrong with the generated mqtt messages.

Regarding configuration:
I had earlier that mqt section in my configuration.yaml but I commented this out, it is not necessary.

Another difference is that in my Mosquitto broker config, I have an additional option:

anonymous: true

But I don’ think this causes your errors.

Please check the mqtt log maybe it reports more relevant details.

Also enable debug logging of the mqqt messages into the general log, by adding the following lines to your configuration.yaml

logger:
  default: info
  logs:
    homeassistant.components.mqtt: debug

Then we will be able to see details of the received messages. like the following from my log:

2021-08-19 23:08:50 DEBUG (MainThread) [homeassistant.components.mqtt] Received message on homeassistant/sensor/etrv/00_04_2f_4E_B8_30_rep_name/config (retained): b'{"name": "danfossstue Reported name", "unique_id": "00_04_2f_4E_B8_30_reported_name", "state_topic": "etrv/danfossstue/state", "value_template": "{{ value_json.name }}", "device": {"identifiers": "00:04:2f:4E:B8:30", "manufacturer": "Danfoss", "model": "eTRV", "name": "danfossstue"}, "availability_topic": "etrv/state", "payload_available": "online", "payload_not_available": "offline"}'

this might help us figure out why they are not considered unique.

Jacob_Hansen · August 19, 2021, 9:57pm

i get a ton of log from the mqtt. but it does still not seem to work.
my bluetooth reciever is located with a pretty weak signal. (from the scan its RSSI=-81dB)

yes i do and previously rpi3 and that worked too

ghassan · August 20, 2021, 10:51pm

This looks fine I guess
are the errors gone from the log?
But your sensors are still unavailable?

ghassan · August 23, 2021, 10:10am

I noticed that your sensors get discovered several times and ignored. logging “Already discovered”

Jacob_Hansen · August 23, 2021, 11:27pm

hi. and thak you very much for your assistance.

i did try to comment out the MQTT part of the configuration. but nothing happend.

further. i just tested it on a raspberry pi 3 model B. and i get the exact same error. well. almost. some of the hex decimals are different.

wich leads me to think that either

there is a module or pice of software that i am mising, or not configured correctly.
or.
the configuration on my setup is not correct.

Jacob_Hansen · August 23, 2021, 11:30pm

or.
3. the thermostat has got new firmware and no longer compatible wuth the script.

ghassan · August 24, 2021, 7:16pm

I am running:

Hardware-revision B4
Firmware-revision: 2.08
Radioprotokolversion: 4.2
which works fine.

Are your versions different?

Jacob_Hansen · August 25, 2021, 12:18pm

Mine has the same values. so that should not be the problem.

Jacob_Hansen · August 26, 2021, 5:07am

do you have some other addon that is bluetooth related ?

ghassan · August 30, 2021, 4:01pm

No other Bluertooth rekated add-on but custom componenets.
try to put the mqtt log level to info, we might get more details

i got it to work. im not too sure what made the difference. but i did a reset

all while pushing the clock button
you pull out battery (disconnect one end)
put it back in
release clock button when a red light is lit.

ghassan · August 31, 2021, 7:56am

Hi everybody,

Just discovered an error that i wanted to warn you about.
I added a new valve and that caused the etrv2 addon to crash with a long error message ending by this:

File "/usr/local/lib/python3.8/site-packages/libetrv/fields/string.py", line 18, in from_raw_value
return raw_value.decode('ascii').strip('\0')
│ └ <method 'decode' of 'bytes' objects>
└ b'Sovev\xc3\xa6relset\x00\x00\x00'
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 5: ordinal not in range(128)`

After some research, I figured out that the error happened because the name of the valve in the Danfoss app, included a Danish letter “soveværelset” that could not be decoded. I changed the name to “Sove” and it did not crash any more.

So be aware of that, and don’t include none English letters

Hi everyone,

I failed to google any reasonable explanation on what “code: 17, error: Invalid Index” means and how to get around it, so I was wondering, someone here might have faced similar issue already and can advise something.

Here are my setup details:

Ubuntu 20.04.3 LTS
Docker version: 20.10.7
