I got from a forum an universal infrared remote controller SMART IR RSH-IR01. Later discovered that this particular version is capable of RF433+RF315.
In due course dismantled for recognizing the inner parts and found the two coil antennas for RF and 6 transmitting leds, one receiving led.
Next surprise was a SHT30 sensor, later recognized as analog Temp sensor.
It has a ESP module of TYWE3S and a chip MRT17S22A16 and one more chip with 4 x 5 pins.
I was spending an evening trying out to flash it with tuya convert method but no success with it.
There are 2 lines, of 6 pinouts each, near the MRT17S22A16 marked as J1, J3 but no other identification.
Eventually installed an Tuya app in an android tablet and I did initiation.
After that, there is no any interaction with HA and I’m wondering if it will be possible to do something useful with it. From what I’ve seen in the net, there is limited quantity of information and mostly for a version without the temp sensor and RF parts.
Any clue how to proceed?
