HA: moisture sensor ValueError: could not convert string to float: '2.1.1'
-
I am attempting to incorporate a moisture sensor into HA but getting could not convert to float errors in the logs. The sensor does show up in mysensors.json but not in the gui.
Home Assistant 0.94.4
I am using a simple FC-28 moisture sensor: VCC, Gnd, D0 connected to D6 of the UNO and A0 connected to D7.

@mrhutchinsonmn - values in mysensors json looks very strange.
"values": { "37": "3" }Not sure what else. did you try to stop HA and remove the node from mysensors json and preesnt it again?
-
Yes, I removed mysensors.json and restarted. I just finished doing a new install of HA in case it was simply a version issue. I have more info now from the logs. What do you make of this output?:```

Could the error comes from the unit of measurement is not mentioned for S_MOISTURE type of sensors? -
I actually have the same problem and do not know where it is coming from.
I tried several time to delete mysensors.json file and restart AH to try to troubleshoot it without success.This is the errors I get exactly:
2020-02-25 19:07:32 ERROR (MainThread) [homeassistant.components.mysensors.device] Error updating Grow monitor 30 3 Traceback (most recent call last): File "/usr/src/homeassistant/homeassistant/components/mysensors/device.py", line 108, in update await self._async_update_callback() File "/usr/src/homeassistant/homeassistant/components/mysensors/device.py", line 134, in _async_update_callback await self.async_update_ha_state(True) File "/usr/src/homeassistant/homeassistant/helpers/entity.py", line 284, in async_update_ha_state self._async_write_ha_state() File "/usr/src/homeassistant/homeassistant/helpers/entity.py", line 330, in _async_write_ha_state unit_of_measurement = self.unit_of_measurement File "/usr/src/homeassistant/homeassistant/components/mysensors/sensor.py", line 85, in unit_of_measurement float(self.gateway.protocol_version) >= 1.5 ValueError: could not convert string to float: '2.3.2'I checked the file mentioned in the last line here: https://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/mysensors/sensor.py
I see that V_LEVEL doesn't have a S_MOISTURE corresponding it to (line 32).
Could the error comes from the unit of measurement is not mentioned for S_MOISTURE type of sensors?@Meach
I guess there's only one way to find out: Add theS_MOISTUREdefinition on line 36 insensors.pymanually, restart HA and give it a try."V_LEVEL": { "S_SOUND": ["dB", "mdi:volume-high"], "S_VIBRATION": ["Hz", None], "S_LIGHT_LEVEL": ["lx", "mdi:white-balance-sunny"], "S_MOISTURE": ["%", "mdi:water-percent"], },Since the measurement in your sketch seems to be tensiometric, I'm not certain if % is the correct unit to choose here, but I guess in general people would assume that
S_MOISTUREis a volumetric measurement representing the percentage of water per volume in the soil. So you might want to change it to[None, "mdi:gauge"]or[kPa, "mdi:gauge"].It's weird though that the logs from both of you complain about the MySensors version string, which of course, isn't a valid float and can't be converted with
float(varString). -
Out of curiosity, I just setup a node with the sketch that @mrhutchinsonmn posted in the first post, but uploaded dummy data instead of measuring actual values (shouldn't be a problem, I just don't have a soil moisture sensor at hand). I also tried the latest version of the SoilMoistSensor.ino sketch.
Unfortunately, I was unable to reproduce the issue. Serial output is fine, the HA log shows no errors, the sensor value is displayed in the GUI. So I doubt that the change mentioned above will have any effect. It's most likely just used to display a default unit and icon in the GUI. If there's no matching sensor type, as is the case with
S_MOISTURE, it will default to a unit-less display. At least that's my understanding.I used MySensors 2.3.2 and Home Assistant 0.105.5 (in Docker).

That particular error went away with a new HA install 0.103.6. However, I continue to get data type and child unknown errors:

I get the "not a valid message" error when I switch back to the old 1.4 protocol, which is still the default in HA.
So I suspect that you are using the old protcol version. Please have a look at your
configuration.yamland see if you specified the current version withversion: '2.0'or even 2.3. It should look something like this:mysensors: gateways: - device: mqtt persistence_file: '/config/mysensors.json' topic_in_prefix: 'mysensors-out' topic_out_prefix: 'mysensors-in' optimistic: false persistence: true retain: true version: '2.0'@Meach's issue might be down to an old HA version then, if an update fixed this particular error.

Yes!! That worked for me!
Thank you!
