Overview Shelly Plus 1

The Shelly Plus 1 is the successor of the Shelly 1 and also switches a potential-free contact. The function block switches the relay via MQTT and reports the state of the relay and of the connected push-button. With the optional Shelly addon, temperature and humidity sensors can be read in addition. As this is a device of the second generation, the topic is entered without shellies/.

Inputs
S1 Switch Switches the relay. The effect depends on the corresponding parameter, see below.

Outputs
S1 Switch 1 status State of the push-button or switch connected to the device.
R1 Relay 1 status Actual state of the relay in the device. Is also updated when switching via the Shelly app or the push-button at the device.
T1 Addon temperature 1 Temperature of the first DS18B20 sensor, or of the DHT22 if that one is selected. Only present when the addon is enabled.
T2 Addon temperature 2 Temperature of the second DS18B20 sensor. Only with the setting "+Addon DS18B20".
T3 Addon temperature 3 Temperature of the third DS18B20 sensor. Only with the setting "+Addon DS18B20".
F1 Addon humidity in % Relative humidity of the DHT22 sensor. Only with the setting "+Addon DHT22"; the output then takes the place of T2.

Parameters

MQTT topic Topic of the device, exactly as in the MQTT settings of the device. Example: shelly1-AABBCCDDEEFF

Switch Behaviour of the corresponding input. Toggle (rising edge) for push-buttons: every change from 0 to 1 toggles the relay. Toggle (1/0) for switches and for control from the program: the value is applied directly.

Addon Evaluation of the optional Shelly addon. None hides the additional outputs. +Addon DS18B20 shows three temperature outputs, +Addon DHT22 one temperature and one humidity output.
In addition to the outputs listed, the command generate addresses creates an address named timeout. It is set to 1 when the device has not sent a message for a longer period of time.
