Control Honeywell Evohome thermostats

IMPORTANT NOTICE If you are upgrading from version 1, you will need to re-enter your username and password in the app settings. Otherwise the app will not work. Also you might need to restart the app once after saving your username/password. Honeywell Evohome With this app you can manage your Evohome and other systems that connect via Total Connect Comfort from within Homey. It is using the unofficial API of Evohome. Supported devices The following devices are known to work with the app: Control systems: - Evohome ( + gateway RFG100 ) - Evohome Wifi - Round Wireless ( + gateway RFG100 ) Thermostats (always in combination with Control system) - HR92 Not in the list? It still could be supported; as long as your thermostat can be controlled via the Total Connect Comfort app, it should be controllable by the Homey app. Feedback is appreciated, so I can adjust the list. Settings After installing the application, first visit the Homey Settings and navigate to the ‘Honeywell Evohome’ application. Fill in your username (email address) and password and press save. Then, go to Devices and add a Honeywell Evohome device. Press thermostat and select which devices you’d like to add into Homey. Flow support Triggers - When temperature changes: triggers a flow when temperature changes - Via device card: individual temperature changes - Via Evohome card: any temperature measurement changes - When target temperature changes: triggers a flow when the target temperature setting changes - Via device card: individual target temperature settings changes Conditions No conditions defined at this moment Actions - Set temperature ; this will set the individual temperature on a device. Attention: there is no way yet to cancel this setting other than setting another temperature or using the Evohome app/system. - Reset temperature: Cancel individual device setting - Cancel all adjustments: Cancel all individual thermostat settings - Execute QuickAction ; these are the generic settings of your Evohome. You can choose between: - Auto: this is the normal mode, Evohome will follow the set program - Economy: this is the economy mode, normally 3 degrees lower than Auto - Heating Off: This will turn your heating off ( with a lower limit of 7 degrees to protect the system from freezing ) - Away: This will set the Evohome system to Away mode - Day Off: This will set the Evohome system to ‘Day off’ mode - Custom: This will set the Evohome system to ‘Custom’ mode; whatever you configured in Evohome itself - Execute QuickAction (manual entry); with this card you can enter the quickaction yourself. This is usefull if you have stored a quickaction value in a variable in Homey, this can be used e.g. to restore a previous setting. e.g. door open, set quickaction for heating off, then when door closes, set quickaction with variable where the previous status was stored (e.g. Auto). All actions are currently on ‘permanent’ mode. In the future there might be timers (e.g. set Economy for two hours). If you need that now, using the Homey built in-timers or the CountDown app to trigger a timed event.

If you have multiple Evohome systems, send me a message, so I can hook you up with a specific second location app. ToDo in order of my priority (donate to change priority ;-) ) - Add multiple location support - Cancel all adjustments in an intelligent way to limit calls to Honeywell - Add target temperature triggers - Low battery detection - Add hot water device support - Check when heating mode is changing ( e.g. following schedule , permament, etc) - Clean-up code - Time limits on quick Actions - Time limits on temperature heatSetpoint - Add timeout to code if Evohome service doesn’t respond - Add error checking in code - Translation to NL Known bugs In order of priority: - When access token of Honeywell expires, the first login might give an error when reading status. Unsure if this also affects when updating; statistically changes are higher with the 5 minute interval. That’s probably why I only see it during the regular_update.
