Multiple PID Termostats - MariusB - 22.10.2020

Hello

I'm a total newbie on scripting, but i'm trying to learn, so please bear with me Smile

I want to add more than one PID termostats. Can i put more than one PID in one Resident skript?

The case is:
I have 2 bedrooms with one temp sensor, and one heater controlled by a KNX in each room. The heaters should only be controllable by visualization.

This is the code for one heater, and it works great, but where can i put in the code for the second heater?

Code:
-- init pid algorithm
-- Panelovn Mikkel
if not p then
  p = PID:init({
    current = '2/2/0',
    setpoint = '2/2/7',
    output = '2/2/6'
  })
end

-- run algorithm
p:run()

I have tried to put it in on the bottom of the code, and inside before p:run()

Only the first one works. The codes are identical for both heaters (except group adresses)

Thanks! Big Grin

Use different variable name for each PID. Do a full script restart via disable/enable after making changes.

Code:
if not p1 then
  p1 = PID:init({
    current = '2/2/0',
    setpoint = '2/2/7',
    output = '2/2/6'
  })

  p2 = PID:init({
    current = '3/2/0',
    setpoint = '3/2/7',
    output = '3/2/6'
  })
end

-- run algorithm
p1:run()
p2:run()
