Sonoff TH Origin (16A) with THS01 (SI7021) sensor

[maxnorth]

I can't figure out what node server yaml entry to use for this setup. I tried the types "analog" and "Temp", but the resulting node device does not show any temps. My tasmota config identifies the Sonoff THS01 temp/humid sensor as a SI7021, and that config is working fine in the Tasmota web setup. It show readings. I am using "SI7021" in the node server as the sensor ID.

From the Tasmota web console:

"18:08:48.992 MQT: tele/sSonoff_THR316/SENSOR = {"Time":"2025-05-18T18:08:48","SI7021":{"Temperature":68.7,"Humidity":51.3,"DewPoint":50.0},"TempUnit":"F"}

I also have a "switch" device for the TH Origin. It is working fine in the node server and the switch device appears in order after the sensor device. Below is an example:

 

- id: "sSonoff_THR316Sens"
  type: "Temp"
  name: "AtticSwTemp_145"
  sensor_id: "SI7021"
  status_topic: "tele/sSonoff_THR316/SENSOR"
  cmd_topic: "cmnd/sSonoff_THR316/power"
- id: "sSonoff_THR316"
  type: "switch"
  name: "AtticSw_145"
  status_topic: "stat/sSonoff_THR316/POWER"
  cmd_topic: "cmnd/sSonoff_THR316/power"

To answer my own question, the correct type to use is "TempHumid." This is working now.

It might be helpful to update the configuration help to list the SI7201 sensor as an acceptable sensor for TempHumid.

Hi @maxnorth,

Glad you figured it out. I will add this to the to-do list for an update. Need to read up on the .MD format as well. As I recall there are/were some compatibility issues with the way PG3 displays more complex layouts...
