Hi,
I am running version core-2021.3.4 on a Linux machine and is pretty new to this. I have a couple of homebuilt ESP8266 sensors to monitor humidity and temperature that are configured for mqtt discovery that work fine. I would like to monitor some temperatures using a couple of DS18B20 connected to one ESP8266 and my problem is to get the (currently) three temperatures to be picked up properly by Home Assistant.
I get no warnings but only one temperature show up (value is zero). The debug info from Home Assistant is as follows:
Topic: homeassistant/sensor/98b/MULTI_DS18B20_98b_T/config
Payload:
device_class: temperature
name: Temperature_35593
state_topic: multi_t/sensor/98b/state
unit_of_measurement: °C
unique_id: T_98b
value_template: >-
{{ value_json.temperature1 },{ value_json.temperature2 },{
value_json.temperature3 }}
device:
identifiers: T_98b
manufacturer: DIY
model: DS18B20
name: ESP8266 Multi Temperature Sensor
sw_version: 1.0.0
platform: mqtt
Subscribed topics:
multi_t/sensor/98b/state
* Received 18:03:10
* QoS: 0
* Payload:
temperature1: '23.06' temperature2: '23.00' temperature3: '23.00'
(and so on)
I have used a mix of decimal and hex representation of the last part of the MAC-address to make each ESP8266 name unique and also some other creative naming.
It is probably a simple thing to correct but most things google find are the non-discovery mqtt integrations.
Any help would be appreciated!
