Hello,
I have been learning to use MQTT on HAOS after using Homeassistant in container mode. I had RTL_433 working fine by and using MQTT to obtain information, as well as adding in sensor in configuration file. Now I am trying to switch to HAOS, and so learning with using ‘add-ons’. I have now add RTL_433 and Mosquito addon in this manner, and configured it. Whilst I have managed to get three of 5 of my values from Mosquito, the two remaining are not playing ball, plus I get error messages, which I can’t think why, plus I have removed the offending string i.e. INT and STR. It still shows up in the log, and so formula that was working using value_json under container mode previously now doesn’t, but found I had to change it to ‘value’ instead and this gave me further result, but not for the other two which I want as well.
So here are the error messages that are showing in the homeassistant log:-
2022-06-08 15:55:51 ERROR (MainThread) [homeassistant.util.logging] Exception in message_received when handling msg on ‘rtl_433/74930c0d-rtl433/devices/Oil-SonicSmart/684266245/depth_cm’: ‘95’

Here are the extract of the script from configuration.yaml:-

Obtain number of Litres left in Tank

unit_of_measurement: 'cm'
Apologies I am not quite advanced on scripting as I am calling same state_topic four times, basically ‘depth_cm’ are my main number to work with, this is read as 95 or 96, which is correct, but I can’t get ‘Bar Oil Percent’ and ‘Bar Oil Tank Litres Left’ but the other two are working OK, even though it has INT in it! Everytime time I get an update (approx every 30mins) I get this errors in the log. So is it the formula or is it MQTT that are causing issue? I am on Home Assistant Core 2022.6.1 (hence the different MQTT sensor layout as advise). I have also check configuration is valid and restart it, I have also done a full shutdown. The error in the log still persists.
MQTT Explorer shows up the follow values:-
Any help would be appricated to ‘fix’ this!
