DS18B20 with Tasmota on ESP-01S

[Superpedro (Peter Busch)]

Hello I´ve a working ESP01 with Tasmota and a connected DS18B20. Tasmota is showing the temperature.

How is the correct way to connect it to Openhab, so I could see the temperature in the panel?

I have a DHT22 connected to a Tasmota device. I use MQTT to communicate between Tasmota and openHAB. Here’s my setup:

[OH2] Tasmota flashed Sonoff Basic with DHT22 via MQTT

Overview I have a number of Sonoff Basic R2 switches around the house, attached to desk lamps, floor standing lamps, or spliced into the wiring for the outdoor porch light. As I already had the ESP8266 inside the Sonoffs at various locations, why not try and add a temperature sensor to them?! Note that whilst I used a DHT22, Tasmota supports a number of different sensors. Just ensure you choose the correct sensor within Tasmota’s Module parameters, and ensure that the name of the sensor is corr…

Thanks, but when I´m using your Thing code, it says:

missing EOF at ‘Type’

Probably best to continue discussion over on that thread.

However, I’ve just re-factored that page (as in, in the last half-hour), so you may want to completely re-do the copy/pasting!

And just to check: what version of openHAB are you running?

Thank you it´s working now

Great! Could you post your Things file below? I’m interested in what your transformationPattern is for this sensor…!

Channels:

	Type number : temperature "Temperature" [

		transformationPattern="JSONPATH:$.DS18B20.Temperature"
	]

}

Hello,

after a reboot of the rasp with openhab, the thermometer sensor show NULL in panel and - C at the basic UI.

Do I have to activate it again?

Thanks4help

You will need to wait up to 5 minutes until the next tele message arrives…

[Superpedro (Peter Busch)]

I don´t know whats wrong.

Only thing - I install a tasmota wemeo d1 with 4 Relais

temperature isn´t show anylonger

[hafniumzinc (T)]

So you have added a second ESP device via MQTT? I presume they have different Client and Topic settings within the Tasmota MQTT parameters? What does your new Things file look like?

Install MQTT Explorer and use it to see whether your MQTT system is working in the first place. Then move back to openHAB.

Thanks for help - looking to the MQTT Editor, everything looks fine. Tasmota 009027 is sending the Temp information and Tasmota D60060shows the actions at the relais Power1 to Power 4

I´m looked in the Terminal and get this warning:

@Superpedro

not supported by type ‘OnOffValue’

The WARN comes from a switch-type channel most likely. The channel settings are looking at some MQTT message that it cannot process correctly.

@Superpedro

Tasmota 009027 is sending the Temp information

Perhaps if you share that we can match it up with your channel config.
