Domoticz

I've made my own motion sensors for enabling motion based lights and I'd like to share my project with you guys!
Using ESP8266, HC-SR501 MQTT and Domoticz I've been able to create these sensors for under €5/piece, including a simple project box.

Please let me know what you think!

Hi, i have read your project and it looks very nice. But i'm a newbie in case of esp8266 and Mqtt. I think i'm going to buy the hardware and in the time it is send i will find out how Mqtt is working.

ciao,
good job!
Just wish to contribute with with 2 notes:

You use a specific node to store the last-seen value (timestamp)... why don't use context data instead and pass the value as it is?

the esp will send a new telegram ONLY if value changes.... your flow will switch off if it does not get a 1 anymore for 15min...
but if you still have movement... your node does not send 1 anymore and you get the flow switch off the variable even if it is not true...
I would suggest to keep the 1 and 0 values from the node and act by consequence, have then domoticz handle the time difference operation

ciao
