Scripting

[mariosp]

Hello mariosp

You should create event script with tag, and this tag should be for two group addresses
for actual temperature object and for temperature set point

Code:

local actual_temp = grp.getvalue('12/0/5')
local setpoint = grp.getvalue('3/1/1')
local pwm_addr = '4/1/1'

local zone0 = 0
local zone1 = 25
local zone2 = 50
local zone3 = 75
local zone4 = 100

local temp_diff = setpoint - actual_temp

--log(temp_diff)

if temp_diff >= 1 then
  grp.write(pwm_addr, zone4)
elseif temp_diff >= 0.7 then
  grp.write(pwm_addr, zone3)
elseif temp_diff >= 0.5 then
  grp.write(pwm_addr, zone2)
elseif temp_diff >= 0.3 then
  grp.write(pwm_addr, zone1)
else
  grp.write(pwm_addr, zone0)
end
