Hey I wanted to share my ESPhome configuration for floodlight.
To begin with previously I was not able to find any floodlight that is sealable after playing around with its guts but now I have found one. It is the Brennenstuhl WF2050P, and it requires removing 4 rubbber cover and 4 screws from top and you are good to go (but You do not have to if you manage to “cloud cut” it) with ESPhome (since libreTiny branch was merged).
This one is not cheapest one but …
Anyway next problem was to template chip. I believe there is space for improvement, so feel free to adjust my code.
My aim was to provide same capabilities as regular app assuming it should be still functional without connection to HA … and I have added few switches to ease adjusting for You use-case.
So:
Action mode: self explanatory
Action mode fallback: time after which manual mode will switch to auto - You probably will forget abut that after party .
Ambient light threshold: level of ADC input used by ambient sensor to determine light conditions - you can tweak voltage levels on code level
Luminance: RAW value of ADC voltage corresponding to current light conditions - i do not know which sensor is used so i did not bother to convert it to lux since it would require me to guess.
Duration after movement: how long led will be on after detecting movement - during being on if PIR sensor will be triggered duration time will reset to this value.
Motion delayed PIR: this is variable responsible directly for switching light
Motion sensor: this is sensor connected directly to Your PIR - You can use it to adjust PIR sensivity
PIR sensitivity: this is PWM output that determines how sensitive PIR is - you can tweak voltage levels on code level
Set Automatic manual mode: if this is on it will switch manual mode if you manually enable light without PIR being True
Set PIR based fallback to auto mode: if this is True it light will switch it mode from manual to auto if PIR is triggered
Set Time based fallback to auto mode: if this is True It will automatically switch to auto mode after being in manual mode for time stated in Action mode fallback, this option is set in code to default as it will be probably most commonly used.
WF2050P Floodlight - light itself
WF2050P WiFi Signal Sensor - I left this because i may have to add external antenna at one point.
If you want to you can dig into code I have added ## adjust.. comment in potentially every place that regular users may be interested.
Probably you will want to turn off loggers.
It should be easy adapting this to any other tuya light only differences probably will be light type and PWM output for PIR adjustment.
Edit:
-
If You are all new to this my post is explaining how to handle
#placeyoursmarked values. Also it contains guide on how to flash it by wire but instead of using ESPhome web flasher refer to next point. -
Also as @amphibitus pointed out in his post to be able to flash esphome for the first time by wire, you will have to use Itchiptool.
