Good day to all!
I have z-wave floor thermostat, raspberry z-wave controller and openhab 1.7.1. I installed need addons (binding, zwave, exec) and created item with bind, sitemap and persistance.
Item: Number Temp_kitchen_floor “Температура пола [%.1f °C]” { zwave=“8:command=sensor_multilevel,sensor_type=1” }
Persistance: Strategies {
default = everyChange
}
Items {
Temp_kitchen_floor : strategy = everyChange
}
Floor temperature is shown right. But once. On system start. Then it’s not update. When I create everyMinute strategy in exec persistance, I get error in log:
