Instead of using netcat, you could use the MaxCmdSend function of the lua time script

Hello, I don't know why, it doesn't run,
I've explored the scripts, and test the MaxCmdSend but only the manual function run properly, Auto and Boost are not recognized ('maybe?)

I was using your script (crontab version) for some time and I was very happy with it. Yesterday I've added two additional "window open sensor" and your script stooped working. (I've added some debug code to it). Could you please help me?

    room_num = string.format("%02X", Room_nums[adr])

print(room_num .. ' ' .. name .. ' ' .. adr .. ' ' .. dtype)

Peggy wrote:Hello,

I've been looking at the market for a while, I saw two options for controlling my 8 radiators :

- Zwave Danfoss popp or LC13
- This Max! solution

Can you tell me whether it is still a good option to go with ELV Max! products starting from scratch?
Because price does matter, I'm ok to spend a bit more time for setting up the Max! solution if all gets perfectly stable and reliable then. Is the cube radio range is enough to control a two storey house?

My current setup is :
- Windows Server
- Domoticz
- Eventghost for my Python scripts/scenarios rather than domoticz, when possible.

Last question : which item should I buy? I can see three. I would prefer the more silent / more efficient.

Thank you by advance for your help, winter is coming

Peggy wrote:- You talk about "Max!'s own web based configuration tool". You did'nt talk about max!buddy. I'm a bit confused, I thought this one was mandatory as a gateway between max! cube and domoticz

Peggy wrote:- You talk about a crontab script, but I'm under windows, I don't know if it is possible to set up a crontab in windows.

Peggy wrote:- About the wall thermostat, I can get the max! one for 27€, so the price is ok. But I already have a temp sensor in the most important rooms (I have 4 bedroom, 2 verandas, 2 living room, 2 kitchen, 2 bathrooms etc.), and a home made custom touch screen in the living room that will evolve with heating control options in the future (see picture under). I you think that a max thermostat brings better comfort (for instance changing temperature), I'm listening to you (you talked about manual override, this is a good reason, but I have so many rooms...).

I'll dig into this story of LUA. To be honnest, unitl now I've been working away from LUA, all my scripts and scenarios are executed in pure python, in an "event based python engine" called Eventghost. This app discusses with domoticz as well as with almost all my gateways (DS18B20, rflink, broadlink, etc.).

I'll look at your lua script (if I'm not too lost, the last version is located here), but maybe I would save time by working directly with a max! python library.

By the way, until now I did'nt understand what you all meant by "switch the boiler", because I didn't imagine it would be a good idea to start/stop the boiler before reading about this. I just discovered how to switch on/off my boiler using a relay, so I'll add this feature in my setup.

Peggy wrote: ↑Monday 18 September 2017 11:36 mvzut,

Your script is interesting, I wish it was in python, but anyway (I won't have time to convert it).
Can you explain this logic?

Code: Select all

if tonumber(setpoint_Domoticz) ~= setpoint_MAX then
    if age(LastUpdate) > interval * 60 then -- Domoticz thermostat value must be updated
		blah
	elseif setpoint_Domoticz ~= setpoint_DoorOpen then -- MAX! setpoint must be updated
		blah

What I understand :

Code: Select all

if domoticz setpoint is different from max setpoint then
    if domoticz setpoint was not changed recently
	     update domoticz setpoint using max value
	else if domoticz setpoint is different from "Door open" setpoint
		update max setpoint using domoticz value

Why isn't there the third condition : "else update max setpoint using door open value" ? Maybe because it is directly managed by the cube?

Peggy wrote: ↑Monday 18 September 2017 11:36 Another thing, in the function ReadThermostat you wrote :

Code: Select all

result, statuscode, content = http.request('http://127.0.0.1:'..DomoticzPort..'/json.htm?type=devices')
  r,e = json:decode(result)

This means you request and parse all Domoticz devices once for each max! device (Domoticz will return 400+ devices in my setup). This call should be outside the ReadThermostat function, called only once.

Peggy wrote: ↑Monday 18 September 2017 11:36 Furthermore, I wonder how to use an external temperature sensor. In your script I see we can send the setpoint to the valve, but not the actual temp. Is it possible to emulate the WMT and send the actual temp to the valve?

Peggy wrote: ↑Monday 18 September 2017 11:36 One last thing, how do I force the valves to "holiday", boost?
