Calculate Delta T of two temperature sensors with lua

Mela 5 Oct 2022, 10:06 last edited by Mela 5 Oct 2022, 10:07

Hi,

Is there an lua expert that can help me, with this?

In domoticz I have 2 temperature sensors, and a dummy Delta-T, I like to make a lua script that uses the two temperature sensors to calculate Delta-T and show me the calculated value in my Dashboard.

I have no lua experience, I always used Blockly to make things work, but blockly have no calculation possibilities.

Thank you.

Advantage of this sensor is fast and easy installing by the non qualified personal. The sensor is designed for large agriculture facility with many greenhouses where is needed to be controlled temperature and humidity, the atmospheric pressure is for control the motor of air inlet and outlet. With help of the sensor installed outside the greenhouse provide information about positive/negative pressure inside the greenhouse. Finlay the software read accurate temp/humid value of the Si7021, and only atmospheric pressure of BMP180, the temperature sensor inside the BMP180 is used only by the sensor itself to provide accurate atmospheric pressure measurements. The sensor can be used also for home automation, and drone applications where is needed correction of the UAV barometric sensor compared to the ground barometric sensor, also humidity measurement can help the pilot to calculate more accurate flying time.

I have added a device editor to the server. It uses the sensor types as a group and the sensor variable as the control. Group (sensor): Control (sensor variable): This will be my last post here because my controller has got it's own controller page

Updated the ESP-IDF from 4.4.0 to latest 5.1.1 and rebuild. Framework updated automatically to framework-arduinoespressif32 @ 3.20004.220825 (2.0.4) Test with 2 sensors on the same pin : Works fine. However there are two no blocking error messages: E (1275) gpio: gpio_isr_handler_remove(480): GPIO isr service is not installed, call gpio_install_isr_service() first Complete startup messages: 163 MCO:BGN:INIT GW,CP=R-NGF---,FQ=240,REL=255,VER=2.3.2 168 MCO:BGN:BFR 169 NM:INIT:VER=1.9-dev 171 NM:INIT:INO=Testcontroller v1.0 174 NM:INIT:LIB VER=2.3.2 CP=R-NGF--- 178 NM:BFR:INIT 1310 GWT:TIN:CONNECTING... 1313 GWT:TIN:IP: 192.168.68.28 1317 MCO:BGN:STP 1335 NM:STP:ID=0 M=0 1340 NM:LOOP:RELAY(1):SET t=2 v=0 1359 NM:MSG:SEND(2) t=42 p=2864B875D0013C99 1392 NM:MSG:SEND(3) t=42 p=28920675D0013CB4 E (1275) gpio: gpio_isr_handler_remove(480): GPIO isr service is not installed, call gpio_install_isr_service() first E (1276) gpio: gpio_isr_handler_remove(480): GPIO isr service is not installed, call gpio_install_isr_service() first 1407 NM:STP:HW V=0 F=240 M=49480 1421 NM:LOOP:RELAY(1):SET t=2 v=0 3424 MCO:REG:NOT NEEDED 3426 MCO:BGN:INIT OK,TSP=NA 3429 NM:MSG:SEND(1) t=2 p=0 3968 NM:LOOP:2864B875D0013C99(2):SET t=0 v=22.75 4537 NM:LOOP:28920675D0013CB4(3):SET t=0 v=22.19 4542 NM:MSG:SEND(2) t=0 p=22.75 4545 NM:MSG:SEND(3) t=0 p=22.19

@Samuel235 I am looking at a CO sensor too, do you have any updates on the ones you are using? What is the exact model?
