Is there an actuator based on 5V? Something what can run on battery?
I have already read through Any TRV suggestions? - #38 by Confused but nothing mentioned of there as well.
So far I find only DIY tutorials:
- Open-Source Thermostatic Radiator Valve (OpenTRV) - Earth Notes
- Smart Radiator Valve With Home Assistant: 8 Steps (with Pictures)
The temperature can be measured using wireless sensors such as:
- A Low-Power Battery-Less Wireless Temperature and Humidity Sensor for the TI PaLFI Device
- XZ-TP10 Low Power Consumption Wireless Temperature Sensor-WIRELESS-TAG TECHNOLOGY CO.,LTD.
- White Paper: Zero Power Wireless Sensors Using Energy Processing - WP-Zero-Power-Wireless-Sensor.pdf
