setting evohome room temp setpoint depending on an dummy thermostat value

[Lebo2d9]

Hi,

I have a honywell evohome system and i set the room temperature with a virtual switch.
on_action http://127.0.0.1:8080/json.htm?type=set ... &used=true
off_action http://127.0.0.1:8080/json.htm?type=set ... &used=true
This is working great.
Now I want that the setpoint is controlled with a virtual thermostat(idx=55) but i don't know how to refer to the idx value.

Can someone help me?

Kind regards

Koen

Depends on what you want....

A setpoint is the temperature you want the room or zone to be.
The evohome has switches to change to different comforts like normal eco etc.

You can feed the temperature from a temp-sensor if you like, but thats not the setpoint you want. As the temp drops, your setpoint also

What's the bigger picture your trying to build???

Reread your post.... Sorry....

You need the GET the value from the Thermostat first, within a script, and that needs to be fed into the switch....

Like the following script i'm getting the setpoint from the thermostat and livingroom temperature from the real thermostat, and feed this into the combined sensor temp-setpoint (which is a virtual one created from the EvoHome (which i don't have).

Code: Select all

pi@domoticz:~/scripts$ cat update_heat_zone_living.sh
#!/bin/bash
#### Description of get_watermeter.sh
#### Purpose:           To read and write Current Living Temp and Thermostat Setpoint from/into Domoticz

#### Functionalities:   Read current temp and setpoint from Domoticz  {curl/json/grep/awk/sed}
####                    Write into combined Zone sensor to Domoticz  {curl/json/grep/awk/sed}
#### This script needs {Unix-style} execute rights (755 - rwx r-x r-x)
#### Declare temporary variables for read/calculate/write
declare    CurrentLiving_Temp
declare    CurrentLiving_SetPoint
declare -i CurrentLiving_Temp_IDX
declare -i CurrentLiving_SetPoint_IDX
declare    HeatZoneLiving_Value
declare -i HeatZoneLiving_IDX

declare DomoURL
DomoURL=$(echo "http://domoticz.internet.address:port")

CurrentLiving_Temp_IDX=468    ### Temperature Sensor (Temperature Tab)
CurrentLiving_SetPoint_IDX=467   ### SetPoint Device (Utility Tab)
HeatZoneLiving_IDX=401      ### Your Zone Device (Temperature Tab) or modify url below the rebuild for the switch!!!!

#### read and calculate current temp and setpoint
CurrentLiving_Temp=$(echo $(curl -s "$(echo $DomoURL)/json.htm?type=devices&rid=$(echo $CurrentLiving_Temp_IDX)" | grep "Data\"" | awk '{print $3}' | sed 's/\"//g' | sed 's/\,//g'| sed 's/\.000//g' ))
CurrentLiving_SetPoint=$(echo $(curl -s "$(echo $DomoURL)/json.htm?type=devices&rid=$(echo $CurrentLiving_SetPoint_IDX)" | grep "Data\"" | awk '{print $3}' | sed 's/\"//g' | sed 's/\,//g'| sed 's/\.000//g' ))

HeatZoneLiving_Value=$(echo $(curl -s "$(echo $DomoURL)/json.htm?type=devices&rid=$(echo $HeatZoneLiving_IDX)" | grep "Data\"" ))

echo $CurrentLiving_Temp
echo $CurrentLiving_SetPoint
echo $HeatZoneLiving_Value

echo "HeatzoneLiving_Value needs to look like....:"
HeatZoneLiving_Value=$(echo $CurrentLiving_Temp";"$CurrentLiving_SetPoint";0;")

echo $HeatZoneLiving_Value
##echo "Electra: "$(echo $M_E_Curr)" kWh    Gas: "$(echo $M_G_Curr)" m3     Water: "$(echo $M_W_Curr)" m3"
curl -s "$(echo $DomoURL)/json.htm?type=command&param=udevice&idx=$(echo $HeatZoneLiving_IDX)&nvalue=0&svalue=$(echo $HeatZoneLiving_Value)"

This has to be run on the commandline or cronjob... But is also implementable in the on/off scriptboxes....

Hope this solves your question better..
