HD-38

PROBLEM DESCRIPTION

A clear and concise description of what the problem is.

I recently purchased a few HD-38 moist sensors. Or atleast, that's what is says on the board:

I have tried literally all options on my ESP8266 with Tasmota, I have used D6 and A0 as pin. No result whatsoever. Any ideas on this, or is it possible to add this sensor?

Wired correctly, you can select between digital and analog outputs. If you want analog, you need to make sure that ADC on ESP8266 gets a voltage in the supported range, 0-1V, not more. Dev boards will normally have a voltage divider to accept up to 3.3V on A0. If correctly setup, and configured on the analog pin (gpio17), Tasmota will be able to show a number, and you have AdcParam to enable extra analog features.

Thanks for your reply. The A0 does give me a value (range). So that’s good.

Next I would like this to be pushed to Domoticz, however, in the domoticz configuration on Tasmota, the range of the sensor is not being pushed to domoticz since there is no option for that. I tried all fields with a dummy idx, but it’s not coming through.

Any thoughts on this?

Use rules. Example.

Use rules. Example.

Not sure how to use this, via console? And do you have an example for A0: ADC Range to Domoticz IDX?

[sfromis]

Well, you need a bit of a learning curve to get started with Rules.
