Python plugin: ELV/EQ-3 MAX!

[mvzut]

That would indeed be great to start with.
...
I'm now waiting on a small voltage supply (220V acdc converter) to power the ESP8266 module to switch the boiler. As soon as I have this, and you have a script ready I can run a test.

I found out it is pretty complicated to switch arbitrary Domoticz devices from within a Python plugin. Therefore, I am working on a plugin version which creates it's own boiler switch. You can then couple this switch to your own "real" boiler switch using it as slave device. The plugin is actually ready, but I want to test it a bit before releasing it.

[mvzut]

I have released an update of the plugin again on Github (version 0.6.0).

This version has an option to create a "Heat demand" switch, which will be turned on when at least one valve requires heat (i.e. if it is open for more than 25%). This 25% is not configurable at this stage, nor is the amount of valves that need to be open before the "Heat demand" switch is turned on. I may add this configurability later. However, since Domoticz plugins do not support more than 6 user-configurable parameters, this will only be possible if I remove other configurable parameters (e.g. the optional creation of certain devices). Actually, I already had to remove one of them (the optional creation of temperature devices) to make this new option possible.

You can use the new "Heat demand" switch to control your boiler. The exact execution of this will differ per situation, since all boilers work differently. You may have to send a command via http, or switch on another device that controls your boiler's thermostat. You can achieve this by creating (Blockly) scripts or configuring other devices as slave of the "Heat demand" switch.

Let me know if this works for you!

P.S. Please restart Domoticz after updating the files with the git commands mentioned in earlier posts. After restarting, go to Devices and set the parameters (again). This is necessary because I made some major changes there.

Interesting! Apparently you don't have to switch to Boost mode per se, any mode switch will do. You could do that by this (slightly modified) Lua time-based script:

Code: Select all

commandArray = {}
valves = {"Mode valve 1","Mode valve 2","Mode valve 3"}
if tonumber(os.date('%M')) == 0 then
  for n, device in pairs(valves) do
    setting = otherdevices_svalues[device]
    if setting == 0 then tempsetting = 10 else tempsetting = 0 end
    table.insert(commandArray, {[device] = "Set Level " .. tempsetting})
    table.insert(commandArray, {[device] = "Set Level " .. setting .. " AFTER 30"})
  end
end
return commandArray

I'll check for a few days if this really works (be my guest to try it as well!). If it does, I'll have a look if I can build something like this into the Python plugin (as a selectable option).

I have this running for a while, seems to update temperature more often now. Have others tried it? If it works well for more people, I might consider adding this functionality to the plugin.

I'm about to try the last update of the plugin and I also want to test the script that acts on the valves every hour, I can use the domoticz editor to include it, or it is necessary to write the file in the folder ~ \ domoticz \ scripts \ lua

No, the internal editor is also fine, just make sure you set it to time-triggered.

Ok gracias...

Después de actualizar el plugin encontrarte algunos errores en el log.

Could it be because I do not have thermostats?
I think you activate the option unintentionally

Sorry, I forgot to explain that after updating the files, Domoticz needs to be restarted completely, not just the plugin. After restarting, you have to go to Devices and set the user configurable parameters of the plugin again. This is because I changed the order & meaning of the parameters.

I expect this will solve your error messages.

Opss ok hahaha ... solved thank you very much.

[AurelioF]

my cost more than expected solve the problem, delete all devices and restart domotiz, but continue the problem, finally change the names in MAX and there are no error messages, although the demand for continuous heat was even with more than one valve in heats greater than 25%

[mvzut]

Ok, I'm not sure I completely understand... Is it working now? And does the heat demand switch work as expected?

The heat demand switch does not work, it always remains OFF

I can start a clean installation, for the moment I am still doing tests.

Mmm... strange. It's working fine here. It seems it's reading "None" as your valve position, don't know why. I've updated the code again with one minor edit, may help to make it at least not crash in those situations. Can you try this, and put debugging on? This will show more status updates in the log.

The last 4 lines are repeated periodically.

The last 4 lines are repeated periodically.

Are the valve percentages updated correctly? And did everything work correctly in the previous version? Somehow (one of) your valves report "None" as percentage. I could send you a version with even more logging to find out what's going wrong. But this will have to wait until tomorrow, no time today. In the meantime, you could try the Lua test script from the Domoticz EQ3 Wiki, and check if all valves report their values correctly.

Until the last update, the operation of the valves was correct, the problems began with the update.
Today I plan to start from the beginning, I will keep you informed.
Thank you

[AurelioF]

I started a clean installation, I'm using Domoticz V. 4.10111, Python Version: 3.5.3, the installation of the plugin worked fine, but after a few minutes it gave an error message.

2018-10-27 20: 57: 19.660 Error: hardware eQ3 (2) thread seems to have ended unexpectedly

After this, no more errors appear, I work all night correctly, but the Heat demand switch never worked, not once.

It seems that - Heat demand does not respond to the heat demands of the valves.
