@Ranjib I would really like it if you would look into updating Tasmota drivers.Somewhere i saw you mention possible adding ESP32 to Reef-Pi if that the case and your serious about it then you really need to take a good look at Tasmota it is the easiest thing i have found for config ESP32/8226 boards and smart devices with those chips. I have 3 NodeMcu/8226 each with 16 GPIO pins but i can only use 1 pin on each NodeMCU but the driver will only allow you to use one GPIO pin, but you can use multiple NodeMCU because each has it own IP addresses. Just think about it with a few line of code add to the Reef-pi driver to able to interpret and few line of code from Tasmota i could have 48 possilde inputs or outputs wireless inputted into Reef-pi. This would open up a whole word of opportunities to reef-pi espicall with people with multiple tanks and the coast of pi's these days. you can by a NodeMCU or ESP 32 for under 12.00us on Amazon and even cheaper if you buy multiples at on time. Config these boards is simple enough that most people including myself cane figure out. So please i beg you take a look at Tasmota. I would be willing to be a beta tester i have 2 pie and there tank, on just being a quarantine tank with on fish that if the whole system cashed because of a new Reef-Pi config/driver it would mater there would be no lose its the perfect test tank.Please let me know i'm sure once more people found out about the uses and possiblily of using Tasmota and ESP32/8226 and the doors it opens you will get alot more request.
