Hello, I use DS2438 to measure tensions ( AD), but I do not manage to post(show) the values under Domotiga.
Thank you in advance for your answers.
Cordially.

Hi, do I feel some tension there?
Can you tell me which 1-wire interface you use, and supply some debug log info (when debug enabled).

Hello, I use the Digitemp module with a DS9097.
With this command (under Digitemp "ludo@ludo:/usr/bin$ digitemp_DS9097 -s/dev/ttyS0 -i -a -A ")
i can see : " Apr 09 08:22:50 Sensor 4 VDD: -1.00 AD: 10.23 C: 19.03 "
I need the value AD which is used to measure one electrical power.
With Domotiga,just the measures °C and H% seem readable.
Cordialy

The last version now stores all three values of a DS2438 sensor.
Where do you use your tension sensors for? Just curious...

Hello,
I use a current transformer with an output 0 .. 10 volts to measure the power consumed by my heat pump.
