Domoticz

#!/bin/bash
php70 -f tado.php > /dev/null &

the PHP script has a 'while true' loop, so it runs indefinitely (unless there is a problem - haven't added any code to deal with this yet) and a variable declared in the start of the script

$sleep_time = "60";

means that it 'sleeps' for 60 seconds each time (i.e. runs once a minute). There is little/no point running more frequently, as Tado does not update more frequently, unless there is a >2% change

It would be nice to have this added to Domoticz as a built-in hardware.

They've introduced 'client_secret' requirement, so the code has been modified (I think the client_secret is the same for all users and linked to the app/client). The code on GitHub has been updated and is working again.

At least I'm getting the actual temp now, great

I wish to use the tado api to find out whether or not tado is current calling for heat and use this to toggle a virtual switch. The end goal is to make 2 set's of electric underfloor heating systems 'smart' by leveraging the power of tado geofencing and heating demand management.

So far I have identified the variable I require and added to the latest version of the script to parse this out as an 'On' or 'Off' variable. However I'm having trouble updating a virtual switch. I added a function to update a switch device but the domoticz switch itself doesn't update.

Below are all my modifications in case it helps someone, maybe @rjblake can incorporate them into his script once we have them working if others will find this useful?

Code: Select all

$tado_heatdemandIDX = "120"; // Your Domoticz DeviceID for the current Tado Heat Demand

$tado_heating_status = get_heating_status($token_file, $home_id, $zone_id);

$DOMO_update = update_switchdevice($tado_heatdemandIDX, $tado_heating_status, $DOMOIPAddress, $DOMOPort, $Username, $Password, $DOMOUpdate);

function get_heating_status($token_file, $home_id, $zone_id) // Gets Status (Heat Demand On/OFF) for ZoneID
{
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, "https://my.tado.com/api/v2/homes/$home_id/zones/$zone_id/state");
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");

	$file = file_get_contents($token_file, true);
	$headers = array();
	$headers[] = "Authorization: Bearer $file";
	curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

	$parsed_json = json_decode(curl_exec($ch), true);
	$heatdemand = $parsed_json['activityDataPoints']['heatingPower']['percentage'];
	if ($heatdemand > 0)
		{$heatingstatus = 'On';}
	else
		{$heatingstatus = 'Off';}
	
	if (curl_errno($ch))
		{
		    echo 'Error:' . curl_error($ch);
		}
	curl_close ($ch);
	return $heatingstatus;	
}

function update_switchdevice($idx, $switchstate, $DOMOIPAddress, $DOMOPort, $Username, $Password, $DOMOUpdate) // Updates Domoticz Devices
{
	if ($DOMOUpdate == 1)
	{	
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($ch, CURLOPT_URL, "http://$Username:$Password@$DOMOIPAddress:$DOMOPort/json.htm?type=command&param=switchlight&idx=$idx&switchcmd=$switchstate");
		curl_exec($ch);
		curl_close($ch);
	}
}

UPDATE 18-9-17

Not sure what I did but it works now. So the script queries tado api to find out whether or not there is currently a demand for heat and uses this to toggle a DOMO virtual switch. I plan to use that virtual switch to trigger sonoff relays. I've also added a check within the script so that it only updates the switch if the demand has changed, rather than continually updating it, therefore I can use logic like - if switch is off and last update was > 10 mins etc etc etc
