timeout of requests

[mph070770]

Can anyone please advise. I have the following crash, which seems to be due to requests, and I'm not sure why:

Traceback (most recent call last):

This is my simplified code:

print ("connecing")
wh = wiserHub.wiserHub(wiserip, wiserkey)
p = pyprowl.Prowl('xxxxx')

try:
	p.verify_key()
	print("Prowl API key successfully verified!")
except Exception as e:
	print("Error verifying Prowl API key: {}".format(e))
	exit()

print("-------------------------------")
print("starting up")
print("-------------------------------")
print ("Model # {}".format(wh.getWiserHubName()))

heating = wh.getHeatingRelayStatus()
hotwater = wh.getHotwaterRelayStatus()

while 1:
    wh.refreshData()
        
    if not (hotwater == wh.getHotwaterRelayStatus()):
        hotwater = wh.getHotwaterRelayStatus()
        print(datetime.datetime.now().time().strftime('%H:%M:%S'), end = ' ')
        print("Hot water status {} ".format(hotwater))
        sendWaterNotification(datetime.datetime.now().time().strftime('%H:%M:%S') +' '+ hotwater)
        

    if not (heating == wh.getHeatingRelayStatus()):
        heating = wh.getHeatingRelayStatus()
        print(datetime.datetime.now().time().strftime('%H:%M:%S'), end = ' ')
        print("Heating status {} ".format(heating))
        sendHeatingNotification(datetime.datetime.now().time().strftime('%H:%M:%S') +' '+ heating)
                
    time.sleep(30)   

The error occurs after a random amount of time - minutes to hours. Any help would be appreciated, thank you.

not 100% sure, could be a networking thing (is this running on a WLAN?) or just the hub becomes busy..

You could try modifying the TIMEOUT constant, on line 39 of wiserHub.py , its currently set to 5s, you could increase it to something like 30 for custom code.

BTW the code was specifically written to support Home Assistant , you should check it it out in https://github.com/asantaga/wiserHomeAssistantPlatform , might be useful as it supports a UI and HA also supports notifications.

Let me know hows this goes
