Outside Temperature

[PvdGulik]

Hello,

Would be nice if your client can set Outside temperature over MQTT by choosing a temperature device from Domoticz. And a field to send other commands.

Just like in the build-in OpenTherm Gateway with LAN-interface in Domoticz.

Thanks!

I was looking into that. Have to find a good way to add this. Because you cannot add a setup page in the hardware page from a python plugin afaik. So would probably be a custom page.

I use the following script that is run from crontab every 15 minutes :

#!/bin/bash

#fetch outside temp (use jq to parse JSON object correctly)
TEMP=`curl -s "http://127.0.0.1:8282/json.htm?type=devices&rid=312"  | jq '.result[0].Temp'`

#post using curl to API
curl -s -H "Content-Type:application/json" -d "OK"  http://10.0.1.196/api/v1/otgw/command/OT=$TEMP

Getting the outside temperature from domoticz on the local host/port, make sure to replace 312 with your device ID, and posting it to OTGW. Use the correct IP address in your situation.

Thanks for the script, was looking for something to add the outside temp.

Hello,

I also try to send the outdoor temperature to the OTGW, but I can't get it to work.

I'm using an odroid N2 with ubuntu and domoticz. Domoticz receives the OTGW value's with MQTT. The only thing I can't get working is sending the OT to the OTGW.

I've edited the bash script with the correct ip-addresses and port. I saved the script in a OT_script.sh file and made it executable with chmod +x OT_script.sh After that I got an jq not recognized error, but I solved that by installing jq. When I run the script now (./OT_script.sh) I get an OK as response, but I don't see the outdoor temperature value on the OTGW webinterface or my thermostat. Can you maybe give me a hint on how to get this working?

What is the ID of your outdoor temp sensor in Domoticz ?

[ocmeros]

The ID of the sensor in Domoticz is 2956.

`

!/bin/bash

fetch outside temp (use jq to parse JSON object correctly)

TEMP=curl -s "http://127.0.0.1:8080/json.htm?type=devices&rid=2956" | jq '.result[0].Temp'

post using curl to API

curl -s -H "Content-Type:application/json" -d "OK" http://192.168.2.21/api/v1/otgw/command/OT=$TEMP ` I also just did a tcpdump on my odroid, and I capture the following message:

15:33:12.303011 IP odroid.home.60844 > otgw.home.http: Flags [P.], seq 1:156, ack 1, win 29200, length 155: HTTP: POST /api/v1/otgw/command/OT=4.8 HTTP/1.1 15:33:12.314155 IP otgw.home.http > odroid.home.60844: Flags [P.], seq 1:84, ack 156, win 1989, length 83: HTTP: HTTP/1.1 200 OK

So I looks like the correct url was send and an OK reply was returned, but no value on the OTGW web interface or thermostat.

Only thing I can think of that to have the temperature visible you need an unsupported code in the exchange so the OTGW can replace that code with the temperature code.

If you change the last line in to curl -X PUT http://otgw.local/api/v1/otgw/command/OT=$TEMP it could work, you can change otgw.local to you ip address if needed. Also check if the url in line four is working.

It worked, but I have to use TO for Outside Temperature instead of OT
