Itho Spider and HGI80 message decoding and control

[DanD]

Hi,

I've been spending the last few days helping another user who's trying to connect the Itho Spider to Domoticz via the HGI80 868Mhz usb device which was also provided by Itho. We've managed to use some of the functions in the Domoticz Evohome code to decode the messages and we're starting to see MQTT type messages. Has anyone attempted to connect the Spider or other Itho device to Domoticz and control via MQTT?

If some of the code's ( log) needed i can proved them so you can read / "decode" them

Some success to report! We've managed to get the HGI80 to communicate with the Spider via Domoticz and it responds to the SYSINFO and ZONE_TEMP requests. Other startup commands are ignored. The next challenge is to try and control the setpoint.

Hi Dan,

Any further news regards the Itho Spider and HGI80? Have you been able to get the setpoint working?

Cheers, Vincent

Nope, not at this moment @Dan did you found something new?

With cosmicgate's help we've made some progress with communicating to the Itho Spider using a HGI80. We've begun trying to send each possible RQ command (0x0001, 0x0002 etc) to the Spider to see if we get a response. Here's a list of the 4 successful responses which have been returned so far (0x0008, 0x0150, 0x01FF and 0x042F):

Code: Select all

045 RP --- 21:049244 18:011808 --:------ 0008 002 0100


045 RP --- 21:049244 18:011808 --:------ 0150 003 010000


045 RP --- 21:049244 18:011808 --:------ 01FF 026 01802B2B2F50008000143C28400000C10480800280FF80040000


045 RP --- 21:049244 18:011808 --:------ 042F 009 0100050009000E1120

I've not attempted to decode these responses yet which is the really difficult bit .

Are there any other Domoticz Itho Spider users who are interested in helping with this? In particular, if you also have the Itho gateway it would make this process a lot easier, although you'd need another HGI80 or similar device to capture the messages between the gateway, the Spider and other devices.

Maybe @stuntteam could help us, they decode a lot for the RFlink software

Hi Dan and others,

Since last week I've got an used Spider with gateway (Fifthplay) and HGI80. Did you get any results? I am offering my help to get this thing to work.

Unfortunately, no. I don't have any of the necessary devices so can't really help progress this much further. I've not seen any info on other forums either where people have attempted to capture and decode any of the messages between the Spider and other heating devices.
