I added a dht22 to the system but was unable to graph the results, all entries disposed of for bad parsing. On investigation my dht22_log (adding throught the sesors modular gui was outputing in log format:
which didn't match the expected format in the graphing script. I made it work by editing the graph script switching the order of temp/ time and adding in some new lines to parse the above format.
try:
item = logitem[curr_line]
item = item.split(">")
date = item[date_pos].split(".")
date0 = date[0]
if "=" in date[0]:
date0 = date[0].split("=")[1]
date = datetime.datetime.strptime(date0, '%Y-%m-%d %H:%M:%S')
if not oldest_allowed_date == "all":
if date < oldest_allowed_date:
print("Stopping reading log at " + str(oldest_allowed_date))
break
temp = item[temp_pos]
if "=" in temp:
temp = temp.split("=")[1]
temp = float(temp)
if temp_unit == 'f':
temp = (1.8*temp) + 32
log_temp.append(temp)
log_date.append(date)
curr_line = curr_line - 1
also changed for humidity section.
was there a better way to do this? modifying log creation commands?

Hi,
I added a dht22 to the system but was unable to graph the results, all entries disposed of for bad parsing. On investigation my dht22_log (adding throught the sesors modular gui was outputing in log format:
time=2020-09-27 19:22:02.292349>humid=44.9>temperature=29.8
which didn't match the expected format in the graphing script. I made it work by editing the graph script switching the order of temp/ time and adding in some new lines to parse the above format.
try: item = logitem[curr_line] item = item.split(">") date = item[date_pos].split(".") date0 = date[0] if "=" in date[0]: date0 = date[0].split("=")[1] date = datetime.datetime.strptime(date0, '%Y-%m-%d %H:%M:%S') if not oldest_allowed_date == "all": if date < oldest_allowed_date: print("Stopping reading log at " + str(oldest_allowed_date)) break temp = item[temp_pos] if "=" in temp: temp = temp.split("=")[1] temp = float(temp) if temp_unit == 'f': temp = (1.8*temp) + 32 log_temp.append(temp) log_date.append(date) curr_line = curr_line - 1
also changed for humidity section.
was there a better way to do this? modifying log creation commands?
thanks for the hard work
